4140 HT Alloy TG&P Shafting. Alloy 4140 is widely used as an alternative to carbon steel where strength and fatigue are a concern. It is a general-purpose alloy used where substantial strength, toughness and hardness are required. 4140 Steel Associated Steel CorporationKROMITE® ECONO-FINISH [4140/4142 (modified) Heat Treated, Decarb-Free, Pre-Machined Alloy] This alloy plate product is 100% decarb-free and blanchard ground top and bottom (+.015/+.035 oversize) for final clean-up. Typical hardness is Rockwell C 28/34.
However, the mechanical properties of this steel will be affected if it is welded in the heat treated condition, and post weld heat treatment should be performed.AISI 4140 Alloy Steel (UNS G41400) - Encore Metals - 4140/4142.

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.
