Project Description

Hot rolling in hot rolled seamless steel pipes is relative to cold rolling, in which cold rolling is rolling below the recrystallization temperature, and hot rolling is rolling at a recrystallization temperature or higher, hot rolled seamless steel pipes The advantage is that it can damage the foundry structure of the steel ingot and eliminate the defects of the microstructure, so that the steel structure is more encrypted and the mechanical properties are improved. WANSTEEL STAINLESS STEEL PIPE TECHNOLOGY CO., LTD. is rich in the manufacture of hot rolled seamless steel pipes. Experience, to ensure product quality, if you are interested, please contact us by email, we will reply as soon as possible
