Definitions
- the present invention relates to a high strength and high formability steel sheet suitable for application to a steel sheet for easy open ends, and a manufacturing method thereof.
- a steel sheet referred to as a double reduced (DR) material may be used for lids, bottoms, bodies of three-pieced cans, drawn cans, or the like.
- DR double reduced
- SR single reduced
- the cold rolling performed again after annealing causes work hardening, and thus although a thin and hard steel sheet can be manufactured, its formability is less than an R material.
- EOEs easy open ends
- steel sheets as materials for manufacturing cans are required to have strengths according to sheet thicknesses, and as for the DR material, a tensile strength of not lower than about 520 MPa is necessary to ensure an economic effect due to thinning thereof. It is difficult to ensure for conventional DR materials both of formability and strength as mentioned above and thus the SR material has been used for EOEs.
- demands for applying the DR material to EOEs also are currently increasing in terms of cost reduction.
- Patent Literature 1 discloses a steel sheet for easy open cans lids excellent in rivet formability, characterized in that its carbon content is not greater than 0.02% and its boron content is in a range of 0.010 to 0.020%, and a manufacturing method thereof, characterized in that second cold rolling is performed with a rolling reduction ratio of not greater than 30%.
- Patent Literature 2 discloses a DR material characterized in that its average Lankford value after an aging treatment is not greater than 1.0, and describes that the DR material is excellent in EOE rivet formability.
- Patent Literature 2 achieves the good rivet formability by reducing the average Lankford value.
- this method exerts its effects only when a rivet is formed by column-like bulging, and when a rivet is formed by sphere-like bulging, the rivet formability becomes insufficient. Therefore, provision of a high strength and high formability steel sheet having a tensile strength of not lower than 520 MPa and an Erichsen value of not less than 5.0 mm has been desired.
- the present invention has been made in view of the above problems, and its object is to provide a high strength and high formability steel sheet and a manufacturing method thereof, which are able to provide a high strength and high formability steel sheet having a tensile strength of not lower than 520 MPa and an Erichsen value of not less than 5.0 mm.
- the inventors of the present invention have found that it is effective, for achieving both formability and strength of a steel sheet, to ensure strength by increasing a nitrogen content while preventing deterioration of formability by restricting a carbon content to an appropriate range, and to restrict a second cold rolling reduction ratio after annealing to an appropriate range. Moreover, the inventors of the present invention have found that it is necessary to restrict also a coiling temperature to an appropriate range because, when the coiling temperature after hot rolling is high, precipitated cementite becomes coarse and local elongation deteriorates. Furthermore, the inventors of the present invention have found that rivet formability by bulging is remarkably improved by providing a resin film layer having an appropriate thickness on a side to be an inner surface of a can.
- a high strength and high formability steel sheet according to the present invention includes, in mass%: greater than 0.020% and less than 0.040% of C; not less than 0.003% and not greater than 0.100% of Si; not less than 0.10% and not greater than 0.60% of Mn; not less than 0.001% and not greater than 0.100% of P; not less than 0.001% and not greater than 0.020% of S; not less than 0.005% and not greater than 0.100% of Al; greater than 0.0130% and not greater than 0.0170% of N; and a remainder being Fe and inevitable impurities, wherein the high strength and high formability steel sheet has: a resin film layer at least on a side to be an inner surface of a can; a tensile strength in a rolling direction of not less than 520 MPa; and an Erichsen value of not less than 5.0 mm.
- a thickness of the resin film layer is preferably in a range of 5 to 100 ⁇ m.
- a method of manufacturing a high strength and high formability steel sheet according to the present invention includes: forming a slab by continuously casting a steel including, in mass%: greater than 0.020% and less than 0.040% of C; not less than 0.003% and not greater than 0.100% of Si; not less than 0.10% and not greater than 0.60% of Mn; not less than 0.001% and not greater than 0.100% of P; not less than 0.001% and not greater than 0.020% of S; not less than 0.005% and not greater than 0.100% of Al; greater than 0.0130% and not greater than 0.0170% of N; and a remainder being Fe and inevitable impurities; performing hot rolling at a slab reheating temperature of not lower than 1150°C; coiling at a temperature of not higher than 600°C; thereafter performing first cold rolling; thereafter performing continuous annealing at a soaking temperature of 600 to 700°C for a soaking period of 10 to 50 seconds; thereafter performing second cold rolling at a reduction ratio of 8.0 to 15.0%; attaching a
- the high strength and high formability steel sheet and the manufacturing method thereof of the present invention it is possible to obtain a high strength and high formability steel sheet having a tensile strength of not lower than 520 MPa and an Erichsen value of not less than 5.0 mm. Further, as a result, it is possible to manufacture a lid with a DR material having a small thickness, without cracking upon EOE rivet formation, and thus to achieve thinning of a steel sheet for EOEs to a great extent.
- the high strength and high formability steel sheet of the present invention can be applied to a steel sheet for easy open ends having tensile strength of not lower than 520 MPa and an Erichsen value of not less than 5.0 mm.
- a steel sheet can be manufactured with steel having carbon content of less than 0.040%, by setting a coiling temperature after hot rolling and a second cold rolling reduction ratio to appropriate conditions, and attaching a resin film on a side to become an inner surface of a can.
- the component composition of the high strength and high formability steel sheet of the present invention is described.
- the high strength and high formability steel sheet of the present invention exerts high formability by suppressing carbon (C) content to small.
- C content When the C content is not less than 0.040%, a steel sheet becomes excessively hard, thus making it impossible to manufacture a thin steel sheet by second cold rolling while ensuring formability.
- the upper limit of C content is set to be less than 0.040%.
- the tensile strength of 520 MPa that is required to obtain significant economic effects resulted by thinning of a steel sheet cannot be obtained.
- the lower limit of C content is set to exceed more than 0.020%.
- the silicon (Si) content exceeds 0.100%, there occur problems of deterioration of surface treatability, deterioration of corrosion resistance, etc.
- the upper limit of Si content is 0.100%.
- the lower limit of Si content is set to be 0.003%.
- the preferable Si content is in a range of not less than 0.003% and not greater than 0.035%.
- Manganese (Mn) has functions of preventing red shortness during hot rolling due to sulfur (S) and of refining crystal grains, and is an element necessary for ensuring the desirable quality of a material.
- S sulfur
- Mn has functions of preventing red shortness during hot rolling due to sulfur (S) and of refining crystal grains, and is an element necessary for ensuring the desirable quality of a material.
- the addition of at least 0.10% or more of Mn is required in order to exert such effects.
- the upper limit of Mn amount is therefore set to be 0.60%.
- the preferable Mn content is in a range of not less than 0.19% and not greater than 0.60%.
- Phosphorus (P) is a harmful element that hardens steel, and deteriorates formability, and in addition, deteriorates also corrosion resistance.
- the upper limit of P content is set to be 0.100%.
- the lower limit of P content is therefore set to be 0.001%.
- the preferable P content is in a range of not less than 0.001% and not greater than 0.015%.
- S exists as inclusions in steel, and is a harmful element causing deterioration of formability and deterioration of corrosion resistance.
- the upper limit of S content is therefore set to be 0.020%.
- the S content is set to be less than 0.001%, the cost for desulfurization becomes excessively high.
- the lower limit of S content is therefore set to be 0.001%.
- the preferable P content is in a range of not less than 0.007% and not greater than 0.014%.
- Aluminum (Al) is an element necessary as deoxidizer in a steelmaking process.
- Al content is small, deoxidation is insufficient, and inclusions increase, thus deteriorating formability.
- the Al content is not less than 0.005%, it can be considered that deoxidation is performed sufficiently.
- the Al content exceeds 0.100%, the frequency of occurrence of surface defects due to alumina clusters, etc. is increased.
- the Al content is therefore set to be not less than 0.005% and not greater than 0.100%.
- N Greater than 0.0130% and not greater than 0.0170%
- N content is increased, instead of reducing C content, to ensure strength.
- the strengthening using N has small effects on bulging formability, and thus it is possible to strengthen a steel sheet without deteriorating an Erichsen value.
- N content is not greater than 0.0130%, the strength necessary for a can lid cannot be obtained.
- the upper limit of N content is therefore set to be 0.0170%.
- the balance other than the components described above is iron (Fe) and inevitable impurities, and may include component elements normally contained in a known steel sheet for welded cans.

- JIS Z 2247 Method of Erichsen cupping test defined in the document "JIS Z 2247".
- the processing form applied on a steel sheet is bulging, which can be regarded as tensile deformation toward all directions parallel to a sheet surface.
- the evaluation of deformability of a steel sheet by such processing requires a test by similar bulging, and the deformability cannot be evaluated with a total elongation value or a Lankford value by the simple uniaxial tensile testing.
- the rivet formation is performed by bulging, and processing for bulging toward the outer side of a can is performed.

- the thickness of a resin film is preferably set to be in a range of 5 to 100 ⁇ m.
- the thickness of a resin film is smaller than 5 ⁇ m, the resin film is fractured in bulging, and it is more possible that the effects are not exerted sufficiently.
- the thickness of a resin film exceeds 100 ⁇ m, the effect of increasing a deformation amount of a steel sheet becomes greater, and a crack of the steel sheet will occur more easily.
- the high strength and high formability steel sheet of the present invention is manufactured, with use of a steel slab having the above composition manufactured by continuous casting, by performing hot rolling at a slab reheating temperature of not lower than 1150°C, coiling it at a temperature of not higher than 600°C, performing first cold rolling, performing continuous annealing at a soaking temperature of 600 to 700°C for a soaking period of 10 to 50 seconds, performing second cold rolling with a reduction ratio of 8.0 to 15.0%, forming a surface treatment film by an electrolytic process, and then attaching a resin film at least on a side to become an inner surface of a can.

- an isophthalic acid copolymerized polyethylene terephthalate film having a copolymerization ratio of 12 mol% was laminated on the both surfaces, and thus a resin coated steel sheet was obtained.
- the laminating was performed in such a manner that a steel sheet heated to 245°C and a film were nipped by a pair of rubber covered rolls so that the film was fused to the metallic sheet, and the laminate was cooled with water within one second after it passed the rubber covered rolls.
- a feed rate of the steel sheet was 40 m/min

- the obtained resin coated steel sheet was subjected to Erichsen test.
- the Erichsen test conforms to Method of Erichsen cupping test defined in the document "JIS Z 2247”, and an Erichsen value (a bulging height at which a penetration crack occurred) was measured using a test piece of 90 mm x 90 mm.
- a rivet for attaching an EOE tab was formed using the obtained resin coated steel sheet, and the rivet formability was evaluated.
- the rivet formation was performed by three phases of press working, and processing for reducing a diameter was performed after bulging to form a spherical-head-formed rivet having a diameter of 4.0 mm and a height of 2.5 mm.

Furthermore, even if the rivet formation is performed, no crack or necking in a thickness direction occurs.
- each of the steel sheets of Comparative Examples No. 7 and No. 9 has such small C and N content that they are lacking in tensile strength.
- the steel sheet of Comparative Example No. 8 has such large C content that the formability is deteriorated by second cold rolling, resulting in the lack in Erichsen value and thus causing a crack in rivet formation.
- the steel sheet of Comparative Example No. 10 has such large N content that a slab crack has occurred in continuous casting.
- the local elongation deteriorates because the coiling temperature after hot rolling is too high, resulting in the lack in Erichsen value and thus causing a crack in rivet formation.
