Stainless steel type S
TECHNICAL DATA SHEET
General notes:
» Martensitic higher carbon steel (Material number 1.4034, DIN X46Cr13, AISI number 420)
» contains from 12.5 to 14.5 wt% chromium
» magnetizable
» can be hardened by heat treatment, forming should be done in the annealed condition
» less resistant to corrosion than the austenitic or ferritic grades
» used where strength and/or hardness are of primary concern and where the environment is relatively mild from
a corrosive standpoint
» typical applications include tweezers and cutting tools for the electronic industry, watch-makers, jewelers and
laboratory and medical applications in mild aggressive chemical environments
