Better corrosion properties than most stainless martensitic steels
This is a high strength, low carbon martensitic stainless steel. In our stock standard condition the steel matrix consists of 80% Martensite, 10% Austenite and 10% Ferrite. This composition allows a low carbon martensitic structure after quenching and tempering.
This grade is designed for applications in slightly corrosive environments, where good fatigue resistance, strength and weldability are required. Specific uses are water turbine parts, propeller shafting, shafting, bolts, shear pins, piston rods and equipment for hydro power stations.
The metallurgy of these steels can be complex and if you need any help concerning usage, heat treatment etc, please do consult our in-house metallurgist for advice specific to your needs.
