Definitions
- 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%.
- 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 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 tensile strength of the high strength and high formability steel sheet of the present invention is set to be not lower than 520 MPa.
- the tensile strength is therefore set to be not lower than 520 MPa.
- the above tensile strength can be measured by Metallic materials-Tensile testing defined in the document "JIS Z 2241".
- the steel sheets of Inventive Examples No. 1 to No. 6 are excellent in strength, and achieve tensile strength of not lower than 520 MPa that is required as an ultrathin steel sheet for cans. Moreover, they are also excellent in formability, and have an Erichsen value of not less than 5.0 mm that is required in EOE processing. 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.
