BS EN 42crmo4 Alloy Steel is a common chromium-molybdenum steel that usually used after quenched and tempered, with high intensity, high hardenability. BS EN 42CrMo4 round steel has better performance than 34CrMo4 steel due to the carbon and chromium content is higher. 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 more preferable in terms of material properties. EN 42CrMo4 alloy engineering steel materials have been widely used in automotive driving elements. Otai Steel is able to supply you prime quality of 42CrMo4 alloy steel materials with wide range.
