We manufacture and supply high-quality ASTM A182 F304 and F304L stainless steel flanges for piping, process equipment, pressure vessels, petrochemical plants, oil & gas facilities, chemical processing plants, food processing, pharmaceutical applications, water treatment systems and general industrial piping.
ASTM A182 F304 and F304L are forged austenitic stainless steel grades based on the widely used 18% chromium / 8% nickel stainless steel family. F304L is the low-carbon version of F304 and is particularly useful where welding and resistance to sensitization/intergranular corrosion are important considerations.
Our F304/F304L flanges can be supplied in various flange types, pressure classes, face configurations, sizes, bore schedules and international standards, subject to the applicable specification and customer requirements.
