FV520B is similar to 17-4PH and combines high strength and toughness with superior corrosion resistance.
FV520B is a martensitic precipitation hardening stainless steel which is capable of being hardened by low-temperature treatment. The alloy boasts superior corrosion resistance when compared to standard martensitic grades. Corrosion resistance compares favourably with 304 stainless steel, and as a result, 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.
Commercial applications for this engineering material include:
We stock FV520B in flats, round bar and square bar.
Our knowledgeable staff and resident metallurgists will be pleased to assist you further on any technical topic. Smiths Metal Centres Limited also boasts an in-house UKAS Accredited Testing Laboratory which is unique within the multi-metal and plastic stockholding sector. We believe this underlines our total commitment to quality and our ethos of being the complete service provider.
