These Stainless Steel 904L Nippo Flanges are martensitic stainless steel that provides good corrosion resistance plus high strength and hardness. A wide range of properties can be developed in our Stainless Steel 904L Spectacle Blind Flanges with different heat treatments and by means of ultimate tensile strengths. Due to its excellent hardenability, these SS 904L Orifice Flanges is capable of being through hardened depending upon carbon content and section size. Exposure of our Stainless Steel 904L Ring Joint Type Flanges to chlorides in everyday type activities is generally satisfactory when proper cleaning is performed after exposure to use. A major use for these Stainless Steel 904L Lap Joint Flanges of heat treatable stainless steels is in cutlery. Our SS 904L Threaded Flanges is tough and form draggy chips with heavy build-up. These SS 904L Socket Weld Flanges displays maximum corrosion resistance when it’s been hardened, tempered, and then polished. Our Stainless Steel 904L Weld Neck Flanges is a 12 % chromium martensitic stainless steel plate that can be heat treated to obtain a wide range of mechanical properties.

 

LIST OF STAINLESS STEEL 904L FLANGES

These Stainless Steel 904L Blind Raised Flanges is generally used for applications which involve mild corrosion, high strength, and heat resistance. Our SS 904L Slip On Raised Flanges are less resistant to corrosion when compared to that of austenitic grades. We are a known producer of SS 904L Flanges, which is irresistible in all environments.
