422 Stainless Steel - Power Plant Services (PPS)

Chemical Composition

422 Stainless Steel

PPS offers 422 stainless steel which is widely used for conditions where temperatures are raised up to 1200°F. The 422 stainless steel can be heat-treated to different high strength levels, depending on the section, form, and application involved. The 422 stainless steel also has good resistance to scaling and oxidation and excellent creep-rupture properties. It contains a balanced composition that consist of a microstructure that is essentially fully tempered martensite after heat treatment.

Common Trade Names for 422 Stainless Steel

  • 422SS
  • Alloy 422
  • 422 Stainless Steel

Applications of 422 Stainless Steel

  • Steam and gas turbine parts
  • Balance chamber
  • Fasteners
  • Studs
  • Bushing
  • Blades

422 Stainless Steel Shapes Available

  • Round
  • Ring
  • Rectangular

422 Stainless Steel Size Range

  • 0.188″ – 30.00 Diameter
  • MAX OD=30.5″
  • Please inquire for size

Chemical Composition

410 Stainless Steel

Our 410 stainless steel can be hardened, straight-chromium stainless steels which combine superior wear resistance of high carbon alloys with the excellent corrosion resistance of chromium stainless steels. It is a martensitic stainless steel that is air or oil hardened and responds perfectly to hardening and tempering operations. In addition 410 stainless steel offers excellent combinations of strength and firmness depending on degree of heat treatments. In the annealed condition, it is a ready choice for forming and cold heading.

Common Trade Names for 410 Stainless Steel

  • 410SS
  • Alloy 410
  • AISI Type 410

Applications of 410 Stainless Steel

  • Steam and gas turbine parts
  • Bushing
  • Fasteners
  • Valve Parts

410 Stainless Steel Shapes Available

  • Round
  • Ring
  • Plate
  • Sheet

410 Stainless Steel Size Range

  • 0.25″ – 17.00″ dia.

  • 1.00″-2.50″ THK
  • 0.30″-1.88″ THK
Stainless Steel Turbine Blades – Application of 403 or 410

Chemical Composition

Stainless Steel 403 Chemical Composition

403 Stainless Steel

The 403 stainless steel is a martensitic alloy, very similar to stainless type 410, except for a slightly lower maximum silicon content and a slightly lower maximum chromium content. Good levels of strength, toughness and ductility may be obtained with this alloy.

Common Trade Names for 403 Stainless Steel

  • 403SS
  • Alloy 403
  • Stainless Steel 403

Applications of 403 Stainless Steel

  • Steam and gas turbine parts
  • Rings
  • Blades
