ASTM A213 304L stainless steel tubing is a 300 series austenitic stainless steel with at least 18% chromium and 8% nickel. It is a standard "18/8 stainless steel", also known as WNR 1.4306 pipe. TP304L stainless steel pipe has a maximum carbon content of 0.035%, which can reduce intergranular corrosion during welding. S30403 material is mainly used in high temperature and high pressure applications, such as boilers, heat exchangers, and pipes and containers in chemical equipment.
