FV520B 1.4594 S45000 Stainless Steel Round Bars Hot Rolled / Forged
FV520B is a martensitic precipitation hardening stainless steel.
It is similar to the more common PH grade 17-4PH.
It combines moderate corrosion resistance with high strength and moderate toughness.
FV520B stainless grade combines the following characteristics:
FV 520B, like 17-4PH, develops its high strength from the precipitation of copper particles in its martensitic matrix.
The supply of this grade is complicated by the mismatch between the “traditional” heat treatment conditions
and those laid down in the EN standard. For example, age hardening at 450°C has long been considered to
give the maximum strength in this grade. Yet, no such heat treatment is recognised in EN 10088-3.
The aerospace standards S143/144/145 are closer to established heat treatments.
The combination of high strength and good corrosion resistance finds uses in:
Pump shafts, impellers, fasteners, fans, valves, hydraulic equipment, turbine blades, aerospace,
nuclear transport flask, medical devices.
