301 Stainless Steel: Datum Tension

Grade 301 stainless steel is an extra hard austenitic stainless steel alloy with exceptional shape control when laser cutting and etching. Type 301 (1.4310) offers high strength and good corrosion resistance at ambient temperatures.

With nominal composition of 17 percent chromium and 7 percent nickel 304 ss is suited to applications that require a high tensile strength of up to 1800 Mpa, to produce tempers ranging from 1/16 Hard to Full Hard.

301 is commonly used in welding, forming and drawing and is ideally suited to component parts that have to withstand great mechanical force. At Datum we can supply thin 301 foils to your required length, we also offer processing services and produce laser cut precision parts directly from coil.


301 is used for parts in a wide variety of industries and applications including:

  • Stencil printing
  • Dental & medical instruments
  • Scrapers and shims
  • Structural components for rail industry
  • Component parts for Aerospace industry
  • Springs & clips for household appliances e.g toasters, ovens
  • Component parts for vehicles & trailers
  • Food production
  • Conveyor belts
  • Wheel covers
  • Automotive trim
