FV520B 1.4594 Hot Forged And Rolled Stainless Steel Round Bars
FV520B 1.4594 Hot Forged And Rolled Stainless Steel Round Bars
FV520B is a martensitic precipitation hardening stainless steel. It is similar to the more common
PH stainless grade 17-4PH.
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.
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.
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.

Heat treatment
Heat assay temperatures, including amount of heating, cooling and assimilation times will alter due to factors
such as the appearance and admeasurement of anniversary steel component.
Added considerations during the calefaction assay action cover the blazon of furnace, abatement boilerplate
and plan breadth alteration facilities. Amuse argue your calefaction assay provider for abounding advice on
calefaction assay of FV520B stainless steel.
