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).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties. 4140HW Alloy Steel Technical DataYield strengths range from 110 ksi through 140 ksi, but we can temper it to other strength levels. When compared with standard 4140 heat treated to the same tensile and yield strengths, 4140HW achieves significantly higher toughness, as measured by impact strength (see Figure 9). 4140HW combines medium carbon content with high-end chromium, AISI 4140 42CrMo4 1.7225 SCM440 - Xingsheng Special AISI 4140 is defined as a low alloy steel which has 1% Cr-Mo as strengthening alloy elements.Compared with AISI 4130, it has a higher carbon content with good balance of strength, toughness ,abrasion and impact resistance and heat treatment capabilities,but poor in weldability characteristics.AISI 4140 is generally supplied in quenched and tempered condition with hardness 28-32HRC.
