Technical Data Sheet: Stainless Anti-Magnetic Tweezers Type "SA"

General Notes:

  • Low carbon austenitic steel (Material Number 1.4404, DIN X2CrNiMo17-12-2, AISI Number 316L, Thyssen Steel)
  • Contains from 16.5 to 18.5 wt% chromium and has important quantities of nickel and molybdenum as additional alloying elements
  • Anti-Magnetic
  • Good corrosion resistance to most chemicals, salts and acids
  • Generally used when corrosion resistance and toughness are primary requirements.
  • Typical applications include electronics assembly, laboratory and medical device applications 
    in mild aggressive chemical environments.
