1.4057 Stainless Steel

One of the most rounded stainless steel grades on the market, 1.4057 stainless steel is an outstanding engineering material for demanding applications. It is a martensitic chromium alloy with exceptional corrosion resistance and versatile thermodynamic properties. Inherently resistant to salt water and scaling at continuous operating temperatures of 870°C, 1.4057 stainless steel is a widely-used engineering alloy for marine applications.

1.4057 stainless steel maintains its high toughness and tensile properties in the quenched and tempered condition. This makes it ideal for bolt and shaft applications. As with other common stainless steel grades, it is resistant to chemical attack from a range of biological media, organic matter, and various corrosive elements. This makes 1.4057 stainless steel uniquely suited for medical and food contact devices, as well as for complex machinery in shipbuilding applications.

Benefits of Using 1.4057 Stainless Steel

  • Good resistance to seawater and water of varying salt concentrations
  • Easily machined into complex parts
  • Suitable for hygiene-critical applications
