PH13-8 Mo H950
PH13-8 Mo Stainless Steel (UNS S13800) is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, superior toughness, and good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. The alloy is produced by vacuum induction melting (VIM) followed by electro-slag remelting (ESR). As a result of this melt practice, excellent macro- and microcleanliness is achieved, and tight compositional control is implemented.
The strengthening mechanism (precipitation hardening in a martensitic matrix) makes it possible to achieve uniform strengthening in heavy sections. Strength and ductility levels can be tailored to the application by varying the aging temperature
Heat Treatable to H950
PH 13-8 Mo Precipitation Hardening Alloy is produced in the annealed condition. This is also called the solution heat treated condition, or Condition A. Solution treat from 1675 to 1725°F (910 to 940°C) for 15 to 30 minutes at temperature. Air cool or oil quench to below 60°F (15°C) to effect complete transformation to martensite. Aging is normally carried out from 950 to 1150°F (510 to 620°C), depending upon the desired final properties. Heat treatment is usually performed in air. Heat treatment of brazed components may be done in inert atmospheres. Reducing atmospheres should not be used because of the potential for hydrogen contamination.
