Custom Stainless Steel Forgings, Flanges & Fittings

R&M Forge and Fittings manufactures high-quality custom forged stainless steel alloys for a wide range of industries and applications. Our stainless steel material capabilities include duplex and super duplex stainless steel.

stainless steel materialStainless steel was developed to degrade less easily than steel due to a minimum of 11% chromium content. Unlike carbon steel, stainless steel is extremely resistant to corrosive environments and applications such as high humidity, salt water, or frequent rain. Passivation properties of stainless build a protective layer when the material is exposed to oxygen. The forging process increases these properties along with tensile strength, grain uniformity, and other factors. 

Duplex stainless steel was developed by the Swedes to combat corrosion caused by chloride and other aggressive chemicals. It contains equal portions of ferrite and austenite, hence its name. Duplex steels are also known for their higher yield strength than many austenitic stainless steels. Forging these materials further increases yield strength and corrosive resistant properties making this material last for extremely long periods under constant use.

stainless steel materialSuper duplex stainless steel contains an even higher content of chromium that provides even greater resistance to caustic solutions such as acids and acid chlorides. Super duplex steel is heavily used in the pulp & paper, and oil & gas industries thanks to its extreme corrosion resistance meaning parts last longer in high-stress applications.
