Stainless Steel Alloy 301, UNS S30100

Type 301 Stainless Steel, often referred to as UNS S30100, is a popular austenitic chromium-nickel stainless steel that is known for its corrosion resistance. Similar to Type 304, Type 301 has lower levels of chromium and nickel which increases its cold work-hardening range.

Type 301 is readily formed and drawn and is has good weldability. It is utilized for a wide variety of applications and industries including:

  • Aircraft parts
  • Truck and trailer bodies
  • Kitchen utensils and table wear
  • Architectural (trim, drainage products, storm door frames)
  • Automotive (trim, wheel, covers)
  • Conveyor Belts
  • Home and industrial appliances
  • Mass transit systems

To be considered Type 301, a stainless steel must have a certain chemical composition that includes:

  • Cr 16-18%
  • Ni 6-8%
  • C 0.15% max
  • Mn 2% max
  • Si .75% max
  • P 0.40% max
  • S .030% max

Type 301 Stainless Steel has a minimum tensile strength of 185,000 PSI and 140,000 PSI yield strength. All the Type 301 stainless steel we supply meets or exceeds the industry’s toughest standards.
