Rolling process of SPA-H steel section

How to distinguish between hot rolled and cold rolled process?
The hot-rolled steel sheet has low strength, easy production and processing, and good plasticity. The process performance of the hot-rolled steel plate is poor (air oxidation and low smoothness), but the plastic deformation is good. Generally, it is medium and thick plate, SPA-H steel section, high compressive strength, high strength, and high surface smoothness. Cold-rolled steel sheets have high strength and relatively difficult production and processing, but they are not easy to deform and have high compressive strength.

EN10083-3 42CrMo4 steel plate delivery status: Heat treatment (normalizing, annealing or high temperature tempering) or non-heat treatment delivery status should be specified in the contract. EN10083-3 42CrMo4 steel plate equivalent materials: JIS SCM440, AISI 4140, GB 42CrMo, SPA-H steel section etc. EN10083-3 42CrMo4 steel plate has high intensity, high hardenability, high fatigue strength and good low-temperature impact toughness.
