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
