Description

Bake hardened steels(BH)

BH steel is made from IF steel, which means that it has less Nb and Ti. The interstitial atoms in BH steel don’t have a big effect on the stamping performance of this type of steel. Furthermore, BH steel is mainly used to make automobile shells, so it doesn’t need to be painted or baked after stamping. The time period for this process is relatively short.
