SAE 4140 surface hardening method:
4140 is a 1% chromium – molybdenum medium harden ability general purpose high tensile steel – generally supplied hardened and tempered in the tensile range of 850 – 1000 Mpa (condition T).4140 is now available with improved mach inability, which greatly increases feeds and/or speeds, while also extending tool life without adversely affecting mechanical properties. Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nit riding.
