42CrMo4 VS 40Cr - Special steel china supplier-OTAI 42CrMo4 steel is an ultra-high strength steel with high strength and toughness. In currentThere are three main materials for drill rods:42CrMo4 steel, 40Cr, C45. 42CrMo4 steel is an ultra-high strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low
42CrMo4 alloy steel has higher strength and hardenability. The 42CrMo4 alloy material also has high fatigue strength and good low-temperature impact toughness. The temper brittleness is not obvious. Although 42CrMo4 steel is more expensive than 41Cr4 steel, it is
Effect of Non-Proportionality in the Fatigue Strength of The purpose of this work is to study the effect of different multiaxial loadings on the 42CrMo4 steel and to improve the understanding about the relation between the fatigue strength and the sequential loading proportionality. The considered loadings were defined with the same history but with different load sequences and equivalent stress.
gue strength (also referred to as the endurance limit) is the stress below which failure does not occur. As the applied stress level is decreased, the number of cycles to failure increases. Normally, the fatigue strength increases as the static tensile strength increases. For example, Fig. 14.2 Schematic of R.R. Moore reversed-bending fatigue
Fatigue Strength of Laser Hardened 42CrMo4 Steel 42CrMo4 0.452 0.221 0.780 0.014 0.021 1.07 0.182 42CrMoS4 0.465 0.219 0.740 0.014 0.020 1.05 0.176 According to the delivery sheets, the steels were heat treated. Since actual strength and hardness corresponded to the declared values, the first stage of the laser treatment and fatigue tests was carried out using the material as received.
Fatigue damage assessments of M10 bolted joint, made of 42CrMo4 heat treatable steel and strength class 10.9, were carried out for different preload forces and variable
High Load Ratio Fatigue Strength and Mean Stress The fatigue strength at a high number of cycles with initial elasticplastic behavior was experimentally investigated on quenched and tempered 42CrMo4 steel. Fatigue tests on unnotched specimens were performed both under load and strain controls, by imposing various

In order to predict fatigue strength of nitrided component of 42CrMo4 steel, a similar approach as proposed by Fathallah and co-workers , has been used. For seek of simplicity and as a first approach, we use the multi-axial HCF criterion of Crossland, which is more appropriate for ductile materials and
Low-cycle fatigue properties of steel 42CrMo4 Request PDFThe main objective of deep rolling of the torsion bar is to increase fatigue strength and life time of the torsion bar. DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive

42CrMo4 is a steel for quenching and tempering, which has a good combination of strength and toughness in the quenched and tempered condition. After the oil quenching, the steel will be through hardened up to 42crmo4 fatigue strength#248;60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.
