ASTM A312 TP304, TP304L Stainless Steel Seamless Pipe For Chemical Industry
ASTM A312 TP304 / 304L stainless steel pipe is the most versatile and most commonly used stainless steel on the market. And these grades are austenitic chromium alloy, also known as “18/8” stainless steel, because the composition of the steel is 18% chromium and 8% nickel.
ASTM A312 TP304 and TP304L are both grades of stainless steel that are specifically designed for use in the chemical industry. These grades offer excellent corrosion resistance and high strength, making them suitable for a wide range of chemical processes.The ASTM A312 specification covers seamless, straight-seam welded, and heavily cold-worked welded austenitic stainless steel pipe intended for high-temperature and general corrosive service. TP304 and TP304L are the most commonly used grades for seamless pipes in this specification.
