Ferrium® S53

UNS #S10500

Ferrium® S53* alloy is a corrosion resistant, ultra-high-strength steel with mechanical properties equal to or better than conventional ultrahigh-strength steels such as 300M and SAE 4340 with the added benefit of general corrosion resistance and improved resistance to stress-corrosion cracking (SCC). Ferrium® S53 utilizes an efficient M2C strengthening dispersion precipitated through tempering while avoiding other carbides. This maximizes strength, wear resistance, and toughness resulting in a unique combination of mechanical properties for a corrosion-resistant steel. The alloy uses a passive oxide film to provide corrosion resistance similar to 440C stainless steel. It also has high hardenability, permitting less severe quench conditions for a given section size and resulting in less distortion during heat treatment. *Manufactured and sold under license from QuesTek Innovations LLC.
