13-8 PH / 1.4534

13-8 PH is a martensitic precipitation-hardening stainless steel. This alloy is double melted in a Vacuum Induction Furnace followed by Consumable Electrode Vacuum Melt (VIM-VAR); or in some instances the 2nd melt is by Electro slag Re-melting (ESR) as specified by the consumer. This Alloy exhibits excellent strength, high hardness, superior toughness, combined with good corrosion resistance. Good transverse toughness properties are achieved by tight chemical composition control, low carbon content, and vacuum melting. 13-8 PH steel provides a wide range of properties through a single precipitation hardening heat treatment.

 This Alloy can be welded providing the use of an inert gas shielding ,Helium is preferred. Corrosion resistance is similar to 304 Stainless, with the greatest resistance in the fully hardened conditions.

Main fields of application of 1.4534

Applications include aircraft structural parts, landing gear components, shafts, valves, fittings and fasteners. Also used for components in the petrochemical industry.

Alloy 13-8PH Precipitation Hardening Alloy is produced in the annealed condition. This is also referred to 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 martensitic. 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. Reducing atmospheres should not be used because of the potential for hydrogen contamination.
