|4140 High Tensile Steel, SCM440, 42CrMo4, ASSAB 709, 7225, EN19, SCM4|
|4140 is a 1% chromium – molybdenum medium hardenability general purpose high tensile steel – generally supplied hardened and tempered in the tensile range of 850 – 1000 Mpa (condition T).
AISI 4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
Pre hardened and tempered 4140 can be further surface hardened by flame or induction hardening and by nitriding.
1.7225 is used extensively in most industry sectors for a wide range of applications such as:
