What are the differences between hot-rolled steel plates and cold-rolled steel plates
The carbon content of hot-rolled steel plates is slightly higher than that of cold-rolled steel plates. The density is the same even if the ingredients are not much different. But if the ingredients are very different, for example, the density of stainless steel, regardless of cold-rolled or hot-...Read more -
Why steel pipe quenching needs to be tempered
The main reasons for tempering steel pipes after quenching are as follows: 1. Obtain the required mechanical properties: the strength and hardness of the steel pipe after quenching is greatly improved, but the plasticity and toughness are significantly reduced. Tempering treatment can improve the...Read more -
