ASME SA 53 Seamless Pipes are Low Carbon Steel Pipes with 0.25 % carbon content with combination of 0.95 % manganese, Tiancheng Group export ASME SA 53 pipes in forms of seamless and welded black and hot-dipped galvanized steel pipe of all dimensions. it's also called mild steel pipes which are easy to produce. ASTM A53 pipes are manufactured by ASME Specification. As it belongs to low Carbon Steel, it can only increase surface hardness by carburizing.
