13-8PH Precipitation Hardening Steel13-8PH VAR (AMS 5629)

Precipitation Hardening Stainless Steel Bar

13/8 PH VAR is in a family of martensitic precipitation hardening stainless steel along with 17/4 PH and 15/5 PH.

It is produced as a consumable electrode, vacuum arc re-melted product offering excellent transverse toughness and ductility even in large section. High strength is developed by a simple low-temperature heat treatment. The various ‘H’ conditions indicate the property combination achieved by heat treatment at the temperature shown in degrees F. Due to the chemical composition and controlled melting practise, 13/8 VAR has an essentially ferrite-free microstructure.

This material has a typical density of 7.8kg/dm³.
