FV520B is a precipitation hardening stainless steel with excellent antigalling characteristics. FV520B has useful resistance to some acid conditions and rusting rate in marine and industrial atmospheres is low. FV520B is subject to pitting corrosion under marine organism growths and crevice corrosion on prolonged immersion.
