General remarks:

  • AISI 304 is an austenitic stainless steel (DIN 1.4301, X5CrNi 18-10) and is the most common type of stainless steel
  • Contains 18 – 20 wt% Chromium and contains significant amounts of Nickel as additional alloy component
  • Normally non-magnetic, but becomes slightly magnetic when cold worked
  • Can not be hardened by heat treatment
  • Can be work hardened, annealing is recommended for stress relieving
  • Good corrosion resistance to most solvents, salts and moderate acids
  • Generally used where corrosion resistance is a requirement
  • Typical applications include tweezers for microscopy, electronic industry, fine mechanics and laboratory
