ASTM A403 / ASME SA403 / EN10253-4 WP304 1.4301 STAINLESS STEEL TEE
Overview:
The ASTM A403 specification covers the standard for wrought austenitic stainless steel pipe fittings, including tees, elbows, reducers, and more. The "WP304" mentioned specifies the grade of stainless steel used for the fittings. In this case, WP304 refers to a non-magnetic, 18-8 austenitic stainless steel containing 18% chromium and 8% nickel.
The ASTM A403 WP304 tee is a pipe fitting with a T-shaped intersection, used to connect three pipes together at 90-degree angles. It is made from ASTM A403 WP304 stainless steel, which provides excellent corrosion resistance, durability, and high-temperature strength.
