High strength: After appropriate heat treatment, 40Cr alloy steel can obtain higher strength, and its yield strength and tensile strength are relatively excellent. For example, in the quenched and tempered state, its tensile strength can reach more than 980MPa, and its yield strength is about 785MPa. It can withstand large loads and is suitable for manufacturing mechanical parts working in high-stress environments, such as engine crankshafts, transmission shafts, etc.
Good toughness: This alloy steel not only has high strength, but also has good toughness. It can effectively absorb energy and avoid brittle fracture when subjected to impact loads. This allows it to work reliably in some occasions that need to withstand dynamic loads or may encounter instantaneous impacts, such as automobile suspension system components, gears, etc., reducing the risk of damage caused by impact.
