Cold Rolled Steel Sheet Tensile Strength

The product is available in five strength levels.

Cold rolled steel sheet tensile strength.

In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. However when cold rolled the tensile strength can increase to 85 000 psi with a yield strength of 70 000 psi. For this reason steel sheets with tensile strength ts of 980 mpa and higher are frequently used in the cabin structure. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel.

The steel s strength is obtained by water quenching from an austenitic temperature resulting in a martensitic microstructure. The yield strength and tensile strength of cold rolled will be higher than hot rolled. 780 1470 n mm grade cold rolled ultra high tensile strength steel sheet. Cold rolled super high tensile strength steel sheet with the level forming formability is at the top level in the industry.

As an example a hot rolled steel product may have a yield strength of 235 mpa. 1 1 this specification covers a cold rolled ultra high strength carbon steel sheet in coils or cut lengths. 2 cold rolled steels product description. Ductility is the extent to which a material can undergo plastic deformation specifically how far a material can be plastically deformed before fracture.

Press hardenable steels phs press hardenable steel phs commonly referred to as mn22b5 or 15b22 is available as cold rolled full hard or annealed and tempered. Yield strength tensile strength and ductility values for steels at room temperature. Jfe steel has developed continuous annealing equip ment1 3 which is necessary in the manufacture of high strength steel sheets and was among the first to com mercialize and expand the use of ultra high strength. 780 1470 n mm grade cold rolled ultra high tensile strength steel sheet.
