Chapter 2 Fundamentals of the Heat Treating of Steel / 11 Steel,however,is by far the most widely used alloy and for averygood reason.Among layman,the reason for steels dominance is usually con-sidered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be rened from ore Heat Treating 4140 steel FAQ anvilfire How-to.1) 4140 is an OK die steel but is not recommended for radical shaped dies such as narrow fullering,crown and so on.2) Fully hardened 4140 ranges from 54 to 59 HRC.But it should be tempered for any heavy use.3) Tempering recommendations from the ASM heat treaters guide for 4140-4142 is a minimum of 400°F.This leaves near full hardness.How To Weld 4140 Steel WELDING ANSWERSAISI 4140 steel is alloyed with chromium and molybdenum,hence the term chromoly steel.The addition of these alloying elements and its relatively high carbon content (around 0.40%) provide this low-alloy steel with excellent strength to weight ratio and make it a lot stronger and harder than standard 1018 and 1020 steels.
