15-5PH Precipitation Hardening Steel15-5PH VAR/ESR (AMS 5659)

Precipitation Hardening Stainless Steel Bar

15/5 PH VAR is a martensitic, precipitation hardening stainless steel containing 4% copper.

It possesses all the advantages of 17/4 PH, including single low-temperature thermal treatment. It also offers excellent transverse notch toughness and ductility and very good uniformity of properties. The mechanical properties in larger sections and forgability are superior to that of 17/4 PH. 15/5 PH VAR is produced by the consumable electrode, vacuum arc re-melted route which enhances ductility and toughness and gives an essentially ferrite-free microstructure.

This alloy has a typical density of 7.8 kg/dm³ and magnetic permeability of 95.
