17-4 PH Stainless Steel

UNS S17400 | AMS 5643 | ASTM A564 | ASTM A693 Grade 630

17-4 PH Stainless Steel is a precipitation hardening martensitic stainless steel. Typical usage is seen in applications requiring high strength and a modest level of corrosion resistance. Strength and toughness desired can be manipulated by temperate range in the heat treatment process.

Typical Applications

  • Pump Shafts
  • Oil Patch
  • Mechanical Seals
  • Aerospace

Cronidur® 30 Stainless Steel

Cronidur® 30, a stainless martensitic steel, has greater corrosion resistance then 440c, and is longer wearing. Applications include aviation, medical engineering, industrial applications, precision mechanics, and many more!

Cronidur® 30 is the ideal solution!

  • For tools and machine parts which need high toughness under static and dynamic stresses
  • For tools and machine parts which are in contact with very corrosive fluids or gases even under bad abrasive conditions
  • Compared to the commonly used tool steels 1.2316, 1.4112 and 1.4125 if higher corrosion resistance is requested
  • And/or if there are higher requirements concerning grindability and polishabilty to achieve better surface conditions
