Alloy Seamless Steel Tube is a type of seamless steel pipe. Alloy pipes are divided into structural seamless pipes and high-pressure heat-resistant alloy pipes. alloy pipe contains more Cr in chemical composition, and has high temperature resistance, low temperature resistance and corrosion resistance.
