Strengthen aluminum forgings, optimizing steel and secondary heat treatment of steel, the overall structural strength is improved by 15% compared with the original product in all aspects (mainly shear resistance, tensile, swing fatigue test, pull-off force test, long-term high-intensity test in extreme environments such as saline-alkali mud)
Ball joint: The balljoint steel is national standard 40CR, which has the best comprehensive mechanical properties; the hardenability of this steel is higher than 45 steel (a high-quality carbon structural steel) and is suitable for high-frequency quenching, flame quenching and other surface hardening treatments.
