16-50Mn, 27SiMn, 40Cr, 12-42CrMo, A333, 12Cr1MoVG etc. alloy seamless steel pipe from China

Alloy Seamless Pipe is mostly made by high-grade steel materials, which contains higher chromium content than carbon seamless steel pipe. The increased chromium content in the pipe means enhanced ability to resist high temperature, low temperature and corrosion. 
The production process of alloy seamless pipe is same as carbon seamless pipe: hot-rolled and cold drawn.
