FV520B Stainless Steel
FV520B is a martensitic precipitation hardening stainless steel that is capable of being hardened by low-temperature treatment. The alloy boasts superior corrosion resistance when compared to standard martensitic grades. Corrosion resistance compares favorably with 304 stainless steel, and as a result, the use of the product in marine atmospheres is typical as the effects of rusting are relatively low. FV520B offers improved corrosion resistance in specific environments and also improved intergranular and pitting corrosion characteristics when compared to 17/4PH. While difficult to machine, the alloy does provide good weldability, although the use of matching consumables is advisable.
