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). 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). BS EN 42CrMo4 1.7225 Alloy Engineering Steel - QiLu 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 more preferable in terms of material properties. EN 42CrMo4 alloy engineering steel materials have been widely used in automotive driving
C steels having low Mn and Si contents and C contents below 0.30 % can be welded without any special precautions. When the C content exceeds 0.30 %, preheating of the casting prior to welding is advisable. The low temperature preheat (120 deg C to 200 deg C) reduces the rate at which heat is extracted from the HAZ adjacent to the weld. EN 10269 Grade 42CrMo4 quenched and tempered (+QT The steel shows a high resistivity to static and dynamic loading. Lowest working temperature -40 °C Further application for mounting elements at increased and lower temperatures.,Quenched and tempered steel for fasteners with specified elevated and/or low temperature properties Evaluation of Varying Ductile Fracture Criteria for 42CrMo Fracturing 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
