FV520B Stainless Steel





China JT Metal is the supplier of FV520B round bar, diameters. A precipitation hardening stainless steel with excellent anti galling characteristics. FV520B offers good corrosion resistance, weldability and is capable of being hardened by low temperature treatment. It has better resistance to intergranular and pitting corrosion that other precipitation hardening grades such as 17/4PH stainless. With corrosion resistance comparable to 304 stainless it is often used in industry and marine environments where rusting rate is low.

Applications

Typical applications include pump shafts, impellers, fasteners, fans, valves, hydraulic equipment used in oil and gas industries, petrochemical, marine and nuclear engineering, and aircraft components such as steam turbine blades.

Corrosion Resistance

FV520B has useful corrosion resistance in modest corrosion environments having similar characteristics to that of austenitic stainless steel grades. It has useful resistance to some acid conditions and has low rusting rate in marine and industrial atmospheres.

Welding

FV520B has good weldability characteristics when using standard techniques. Oxy-acetylene welding is not recommended due to the possible pick up of carbon. We recommend you contact your welding consumables supplier who should provide you full assistance and information on welding FV520B stainless steel.
