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
• good corrosion resistance to most chemicals, salts and acids
• generally used where corrosion resistance and toughness are primary requirements
• typical applications include tweezers for the electronic industry, watch-makers, jewelers and
laboratory and medical applications in moderately aggressive chemical environments
