Heat treatment of two-layer plates of St. 3 steel cladded with high-chromium stainless steels 0Kh17T and Kh25T

Conclusion The optimal heat treatment for bimetals, guaranteeing the mechanical properties specified in GOST 10885-64 and the possibility of shearing and cold straightening, was a multistage treatment consisting of heating to 830–850°C, soaking 20–30 min, slow cooling to a temperature below Ac₁, and quenching in water. This treatment can be replaced by a double heat treatment consisting of normalization at 830–850°C followed by quenching in water from 650–700°C.TsNIIChERMET, Chelyabinsk Metallurgical Plant.
