The XCMG loader swing frame (400703743) is typically fabricated from high-strength low-alloy (HSLA) steel, selected for exceptional load-bearing capacity, fatigue resistance, and durability under heavy operational stress.
Heat Treatment: Post-machining, components undergo quenching (850–900°C) and tempering (200–300°C) to achieve a hardness of 28–32 HRC, balancing toughness and wear resistance.
Surface Enhancement: Shot peening is applied to stress-relieve surfaces, followed by electrophoretic coating (20–30μm) or zinc-nickel plating for corrosion protection in harsh environments.
