TECHNICAL CARD 42CrMo4 PRINCIPAL APPLICATION FIELDS Heat treatable steel: Alloyed heat treatable steel with a typical tensile strength of 900 -1200 N/mm². Used for highly stressed components, where the combination of high strength with tenaciousness is of utmost importance.
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 , 42crmo4 hardness
AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.
Working hardness: 27 (min. hardness / delivery condition) - 48 HRC. Applications The Heat-Treatable Steel AISI/SAE 4140+QT is suitable for the following applications: Machine construction, machine parts, axes, knuckles, connecting rods, crankshafts, gear shafts, pinions, gears, bandages, base plates, assembling parts.
42CrMo4 grade steel is a versatile low alloy steel that possesses good tensile and shock resistance properties combined with ductility. Its resistance to wear can be considerably increased by flame hardening or nitriding (for maximum wear and abrasion resistance).

Hardening and tempering anvil and die steel. 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. The following table is extrapolated from a hardness graph given in Brinell, 42crmo4 hardness
However, A514 is a quenched and tempered steel. You will be affecting its properties. More preheat means slower cooling rate which may increase ductility but reduce hardness and strength. To properly answer this question we need to understand the service requirements of the A514 in terms of hardness, toughness, strength and ductility.
