ASTM A182 F304， F304L Stainless Steel Socket Weld Full Coupling， Half Coupling B16.11
Stainless Steel 304， 304L is the ideal choice for forged fittings because of its inherent properties. This steel material can withstand high temperatures， making it a good choice for industrial applications. It is also strong， durable， and rust-proof， corrosion-resistant. Stainless steel 304 also has excellent ductility and weldability.
ASTM A182 F304 Stainless Steel Forged Couplings have high tensile strength， so they are commonly applied in condensers， gas pipelines， and nuclear sector. Forging is one of the oldest ways of shaping metal products， and it increases mechanical qualities like impact resistance， fatigue， and corrosion. ASTM A182 F304 Stainless Steel Forged Pipe Fittings come in various shapes and sizes， including elbows， tees， and couplings. They are widely used in industrial and commercial piping systems due to their high strength， good durability， and excellent resistance to corrosion.
