316/316L Stainless Steel

UNS S31600/03 | ASTM A182 | ASTM A276 | ASTM A479

Stainless Steel 316 or 316L stainless steel is a Chromium-Nickel stainless steel with added molybdenum to increase corrosion resistance and mechanical properties.

It is non-magnetic in the annealed condition and not hardenable by heat treatment. Please contact Progressive Alloy for more information about how 316 SS can best suit your specific application. We also distribute a variety of other grades of stainless steel, including 410 Stainless Steel.

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
