EMS Technical Data Sheets
Tweezers Style 5TTH
EMS Catalog #78320-5TTH
Stainless steel type SA
General notes:
- -Low carbon austenitic steel (Material number 1.4435, DIN X2CrNiMo18-14-3, AISI number 316L)
- - contains from 16.5 to 18.5 wt% chromium and has important quantities of nickel and molybdenum as additional alloying elements
- - non-magnetizable (80%)
- - good corrosion resistance to most chemicals, salts and acids
- - generally used where corrosion resistance and toughness are primary requirements
- - excellent corrosion resistance to most chemicals, salts and acids
- - typical applications include tweezers for the electronic industry, watch-makers, jewelers and laboratory and
medical applications in moderately aggressive chemical environments
