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.
42CrMo4 High Grade Molybdenum Alloy steelApr 17, 2018 · The elongation property of 42CrMo4 steel varies with the heat treatment process and thickness but it is indicated typically 11%. 42CrMo4 can be welded by all fusion and resistance methods. But it is not weld able with oxyacetylene welding methods.
Description 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).

The purpose of the current investigation is to substitute the polymer solution by a waterair spray in induction hardening equipment for surface hardening spur gearwheels made of 42CrMo4 hardening and tempering steel.
EN19 Steel 4140 1.7225 SCM440 42CrMo4 - OTAI Flame or induction hardening can give a case hardness of 50 HRC or higher. EN19 equivalent material with AISI 4140, DIN 42CrMo4 EN 1.7225, GB 42CrMo, JIS SCM440C alloy engineering steel Mechanical properties of steel EN19 (1.7225) Rm Tensile strength (MPa) (+AC)
Jul 14, 2014 · Tribological behaviour of induction hardened ISO 42CrMo4 low alloy steel was evaluated under unlubricated sliding conditions. The effect of hardening depth and test conditions on the friction and wear properties was investigated. The tribological tests were carried out on a reciprocating tribometer. Cylinder-on-flat contact configuration was adopted.
High Tensile Steel AISI4140 EN19 709 1.7225 High Tensile Steel, AISI 4140, SCM440, 42CrMo4, ASSAB 709, 7225, EN19, SCM4 Pre hardened and tempered steel 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:Adapters, Arbors, Axle Shafts, Bolts, Crankshafts
Induction hardened - HYDRAULICS s.r.o.Jan 11, 2019 · Induction hardening is a form of heat treatment where the rod is inductively heated and then quickly cooled down. This treatment increases hardness of the surface of the rod, but also makes it more brittle. As a result, its abrasion resistance increases and the core of the rod remains tough. Material 42CrMo4-IH.
Bulk hardening and induction surface hardening as two different post-deposition heat treatments are applied on TiN-coated 42CrMo4 (AISI 4140) substrates. The results show great advantages of induction surface hardening because only low distortion appear and the properties of the steel substrates are improved without loosing good coating properties.
Tempering Induction Hardened 42CrMo4 Steel Helical Jul 16, 2013 · During induction hardening of helical gearwheels made of 42CrMo4 heattreating steel using a controlled quenching by means of spray cooling,
Through hardening 42CrMo4. - Gear & Pulley engineering Nov 08, 2006 · RE:Through hardening 42CrMo4. TVP (Materials) 7 Nov 06 15:16 According to ISO 6336-5, the contact stress (1140 MPa) and bending stress (450-600 MPa) are well within the limits of a properly induction hardened gear.
