(PDF) Fatigue behaviour of 42CrMo4 steel under contact

For each hardness (28 HRc, 45 HRc and 54 HRc) multiple m easurements were carried out. Fig. 2. (a) experimentally determ ined for 42CrMo4 steel at 28 Hrc, 45 HRc and 54 HRc. As this material 1.7225 Material 42CrMo4 +QT Steel Chemical Composition 42CrMo4 +QT Steel (1.7225 Material) 42CrMo4 material (1.7225 steel) is an European standard alloy steel, the delivery condition of this steel is mostly tempered and quenched, it has high strength, high toughness, good hardenability, temper brittleness, high fatigue limit, good impact resistance after quenching and tempering, and good low temperature impact toughness.

42CrMo4 Alloy Steel, BS EN 10250 Engineering Steel

BS EN 42CrMo4 Alloy Steel is a common Chromium-Molybdenum steel. Otai steel supplies prime 42CrMo4 alloy steel which is widely used as engineering steel. 42CrMo4, 1.7225, 42CrMoS4, AISI 4140, 42CD4, 708M40 42CrMo4, 1.7225, 42CrMoS4, 1.7227, AISI 4140 description. Structural steel, strong and hardenable. With this steel one can achieve very good properties on the whole cross-section (while quenching in oil, the max diameter is 70mm, for quenching in water it is 50mm). In the surface hardened condition in achieves a hardness of 54-59 HRC on the 42CrMoS4 +QT (1.7227) Steel 42CrMoS4V Material 42CrMoS4+QT (1.7227) steel 42CrMoS4V material mechanical properties, chemical composition, Rockwell hardness HRC, heat treatment, equivalent, tensile & yield strength

Wear tests were performed using a ball-on-disc tribological tester. In this study, 42CrMo4 steel disc of hardness 40 HRC co-acted with 100Cr6 steel ball with hardness of 60 HRC. Correlation between thermal properties and hardness of end Jul 10, 2008 · The thermal properties, the Rockwell hardness (HRC) and the microstructure of three end-quench bar (Jominy bar) steels (C48, 42CrMo4 and 35NiCrMo16) have been investigated. The thermal properties are determined using photothermal deflection (PTD) technique and the hardness is measured by the Rockwell durometer. Induction Hardening Steel GradesTo achieve the hardness specified for your part with induction heat treatment, the right steel grade must be selected. The greatest hardness range directly correlates to the carbon content of the steel being used. To help you develop accurate parts and specify reasonable tolerances for hardness and case depth results, Zion Industries has created the following guidelines for the maximum surface
