Technical delivery conditions for steels for quenching and tempering:EN 10250-3:2000 Open steel die forgings for general engineering purposes. 42CrMo4 - Ovako42CrMo4 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 ø60 mm bar diameter. The microstructure of larger dimensions is not fully martensite. The steel is applicable to induction hardening.

High room and elevated temperature strength.Good creep. High notch tolerance. Thermal expansion coefficients compatible with low alloy steel turbine casing materials 42CrMo4 High Grade Molybdenum Alloy steelApr 17, 2018 · High grade steel 42CrMo4 has very low weldability. A process of preheating the base steel to 200 to 300°C is extremely. The temperature should not exceed from this range as it can damage chrome layer. Alloy grade 42CrMo4 can be welded with the help of friction.

AISI 4140 alloy steel round bar sheet plate has high fatigue strength and low notch sensitivity. Low-temperature impact toughness is also very high, no obvious temper brittleness. Evaluation of Varying Ductile Fracture Criteria for 42CrMo

    • AbstractIntroductionExperimental ProcedureFlow Stress BehaviorDamage ComputationComputation ResultsConclusionsFracturing by ductile damage occurs quite naturally in metal forming processes, and ductile fracture of strain-softening alloy, here 42CrMo steel, cannot be evaluated through simple procedures such as tension testing. Under these circumstances, it is very significant and economical to find a way to evaluate the ductile fracture criteria (DFC) and identify the relationships between damage evolution and deformation conditions. Under the guidance of the Cockcroft-Latham fracture criteria, an innovative appParameters on the Microstructure, Hardness, and Strain Apr 26, 2020 · materials Article E ect of Annealing Time and Temperature Parameters on the Microstructure, Hardness, and Strain-Hardening Coe cients of 42CrMo4 Steel Mirosaw Szala 1,* , Grzegorz Winiarski 2, ukasz Wójcik 2 and Tomasz Bulzak 2 1 Department of Materials Engineering, Faculty of Mechanical Engineering, Lublin University of Technology, Nadbystrzycka 36D, 20-618

      Nov 06, 2020 · Elongated carbides precipitated along grain and martensitic lath/packet/block boundaries at low tempering temperatures (500 and 550 °C), then break up, globulize, and finally grow to yield a more uniform distribution as the tempering temperature increases. Hardness varies linearly with the tempering temperature in this 42CrMo4 quenched 42CrMo4 Steel Round Bar / Plate 1.7225 -EN 10083 - OATI DIN 42CrMo4 alloy material also has high fatigue strength and good low-temperature impact toughness.
