Abstract
The present invention discloses a 500MPa grade steel for construction machinery and a manufacturing method thereof. The steel grade comprises the following components by mass percentage: C: 0.12-0.23%, Si: 0.10-0.60%, Mn: 0.80-1.90%, P: <0.018%, S: <0.010%; and one or more of Cr: 0-0.50%, Ni: 0-0.60%, Mo: 0-0.45%, Cu: 0-0.40%, Nb: 0-0.060%, V: 0-0.15%, Ti: 0-0.12%, B: 0-0.0030% and Al: 0.010-0.050%; with the balance being Fe and unavoidable impurities. Its metallographic structure is a uniform and fine martensite high-temperature tempered structure, with good mechanical properties and fatigue properties. Its fatigue life is significantly improved compared with existing engineering machinery steel grades.
