FV520B沉淀硬化不锈钢

FV520B是沉淀硬化不锈钢，具有优异的抗磨损性能，是风机部件多选择钢种，比17-4PH各方面性能更加优越。

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.

FV520B is similar to 17-4PH and combines high strength and toughness with superior corrosion resistance.
FV520B Precipitation Hardening Stainless Steel Excellent Anti-Galling Properties.
