Material for EM-Tec high precision anti-magnetic tweezers

Introduction
The material used for manufacturing the EM-Tec high precision anti-magnetic tweezers is a selected grade of low carbon AISI 316L stainless steel.


It is used for the following types of EM-Tec tweezers:


General remarks:

  • AISI 316L is a low carbon austenitic stainless steel (DIN 1.4435,  X2CrNiMo 18-14-3)
  • Contains 17 – 19 wt% Chromium and contains significant amounts of Nickel and Molybdenum as additional alloy components
  • Non-magnetisable
  • Can not be hardened by heat treatment
  • Can be work hardened, annealing is recommended for stress relieving
  • Good corrosion resistance to most chemicals, salts and acids
  • Generally used where corrosion resistance and toughness are primary requirements
  • Typical applications include tweezers for microscopy, electronic industry, fine mechanics, laboratory and medical in moderately aggressive chemical requirements
