Definitions
- the present invention relates to hot rolled steel with very high resistance, and to a method of manufacturing strips of this steel, the structure of which is bainito-martensitic and can contain up to 5% of ferrite.
- Very high strength steels have been developed in recent years, in particular to meet the specific needs of the automotive industry, which are in particular the reduction of the weight and therefore of the thickness of the parts, and the improvement of safety. which involves increasing the resistance to fatigue and the impact resistance of the parts. These improvements must not further deteriorate the formability of the sheets used for the manufacture of the parts.
- the improvement of the impact resistance of shaped parts can be achieved in different ways and, in particular, by using steels having on the one hand a significant elongation A and, on the other hand, a ratio
- the fatigue resistance of the parts defines their service life according to the stresses undergone, and can be improved by increasing the tensile strength Rm of the steel.
- the increase in strength deteriorates the formability of the steel, thus limiting the workpieces, in particular as regards their thickness.
- very high strength steel in the context of the present invention, a steel whose tensile strength Rm is greater than 800 MPa.
- a first family of very high strength steels is known, which are steels containing high proportions of carbon (more than 0.1%) and manganese (more than 1.2%) and whose structure is entirely martensitic. They have a resistance of more than 1000 MPa, obtained by a quenching heat treatment, but have an elongation A of less than 8% which prohibits any shaping.
- a second family of very high strength steels is made up of so-called dual phase steels, with a structure comprising around 10% ferrite and 90% martensite. These steels have very good formability, but resistance levels not exceeding 800 MPa.
- the object of the present invention is to remedy the drawbacks of the steels of the prior art by proposing a hot-rolled steel with very high resistance, suitable for shaping, and having improved fatigue resistance and impact resistance.
- the invention has for first object a hot rolled steel with very high resistance, characterized in that its chemical composition comprises, by weight:
- the chemical composition also comprises, by weight:
- the structure of the steel according to the invention consists of 70 to 90% of bainite, 10 to 30% of martensite and 0 to 5% of ferrite, and more particularly preferably , 70 to 85% bainite, 15 to 30% martensite and 0 to 5% ferrite.
- the steel according to the invention can also include the following characteristics, alone or in combination:
- the second object of the invention is also a process for manufacturing a strip of hot rolled steel with very high resistance according to the invention, in which a slab is hot rolled, the composition of which comprises:
- the rolling temperature being less than 950 ° C
- the strip thus obtained is cooled to a temperature less than or equal to 400 ° C, maintaining a cooling rate greater than 50 ° C / s between 800 and 700 ° C, then said strip is wound at a winding temperature less than or equal to 250 ° C.
- composition of the slab is as follows:
- the strip of hot-rolled steel is coated with zinc or a zinc alloy, by immersion in a bath of zinc or of molten zinc alloy, at the end of the winding and after being unwound and then annealed.
- the method according to the invention consists first of all in hot rolling a slab of specific composition, in order to obtain a homogeneous structure.
- the rolling temperature is less than 950 ° C, and preferably less than 900 ° C.
- the strip thus obtained is cooled to a temperature less than or equal to 400 ° C, maintaining a cooling rate greater than 50 ° C / s between 800 and 700 ° C.
- This rapid cooling is carried out so that less than 5% of ferrite is formed, the presence of which is not desired, since the titanium would preferentially precipitate in this phase.
- This cooling rate is preferably between 50 ° C / s and 200 ° C / s.
- the method then consists in winding the strip at a winding temperature less than or equal to 250 ° C. We limit the temperature of this step in order to avoid causing an income from martensite, which would decrease the mechanical strength and raise the elastic limit, resulting in a poor E / Rm ratio.
- composition according to the invention comprises carbon at a content of between 0.05% and 0.100%.
- This element is essential for obtaining good mechanical characteristics, but must not be present in too large a quantity, because it could generate segregations.
- a carbon content of less than 0.100 makes it possible in particular to have good weldability, and an improvement in shaping properties and endurance limit. It also includes manganese at a content between 0.05% and 0.100%.
- the composition also includes chromium at a content of between 0.50% and 1.0%. A minimum content of 0.50% promotes the appearance of bainite in the microstructure. Its content is however limited to 1.0% since a high chromium content would favor the increase in the amount of ferrite formed beyond 5%, due to its alphagenic character.
- the composition also includes silicon at a content of between 0.05% and 0.3%. It greatly improves the yield strength of steel while slightly reducing its ductility and deteriorating its coatability, which explains why its content is limited.
- the composition also comprises titanium at a content of between 0.05 and 0.1%. This element makes it possible to significantly increase the mechanical characteristics by a phenomenon of precipitation during rolling and cooling. It does not increase hot hardness due to its moderate content. Its content is limited to 0.1% to avoid degrading the impact resistance properties, the hardness when hot, as well as the ability to fold.
- the composition may also include phosphorus at a content of less than 0.05%, since beyond it could cause problems of segregation during continuous casting.
- the composition also comprises aluminum with a content of less than 0.07%, which occurs during the calming of the steel during its production at the steelworks.
- the rest of the composition consists of iron and unavoidable impurities resulting from processing.
- Rp0,2 elastic limit in MPa
- A elongation, measured in%
- the microstructure of test 1, according to the invention is bainitomartensitic, while the microstructure of tests 2 and 3 is ferrito-martensitic. It is found that a cooling rate between 800 and 700C of less than 50 ° C / s, induces the presence of ferrite in a proportion greater than 5%. The titanium will then precipitate in this ferrite, which no longer makes it possible to obtain the level of mechanical characteristics sought, in particular a high Rm. Furthermore, a winding temperature above 250 ° C, associated with a cooling rate between 800 and 700 ° C below 50 ° C / s, increases the elastic limit without increasing the mechanical strength. The E / Rm ratio is therefore too high.
- the steel according to the invention has a good ability to be coated by immersion in a bath of molten metal, such as zinc or a zinc alloy, or only aluminum or one of its alloys.
