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.
Cromax 42CrMo4 has only limited weldability. Preheating to 200-300C is strongly recommended; the upper limit should not be exceeded because of risk for deterioration of the chrome layer. Cromax 42CrMo4 can be friction welded. However, precautions are necessary so as to limit the formation of undesirable microstructures in the welded zone. MACHINING:
42CrMo4 can be welded by all fusion and resistance methods. But it is not weld able with oxyacetylene welding methods. The yield strength of this grade alloy steel is expressed in Newton per millimeters and it must be at-least 550 N/mm2 (MPa). High grade steel 42CrMo4 has very low weldability.

This analogy is valid for conventional machine-tools, as well as for CNC and high speed machining (HSC) centers. Material
Machinability Machinability of this alloy is good in the annealed condition. In the heat treated and quenched condition machining is best limited to finish grinding. Corrosion Resistance This alloy is a steel and is not corrosion resistant. Protective coating must be used in corrosive, or water, environments.
