>> Premium Materials for Durability and Strength

• High-quality steel is usually used, such as 40Cr or 45# steel. 40Cr has good hardenability. After quenching and tempering, it can obtain high strength, high toughness and good wear resistance, and can better withstand the large alternating loads and impact forces that the pin shaft of the excavator is subjected to under complex working conditions. 45# steel has high strength and good cutting performance. After appropriate heat treatment, such as quenching and tempering, it can obtain good comprehensive mechanical properties, which can meet the requirements of the pin shaft to withstand certain loads and frequent movement friction during work.

• Raw material preparation: Select suitable steel such as 40Cr or 45# steel, inspect the appearance, chemical composition and mechanical properties of the material, and cut the material with cutting equipment.

• Forging processing: Heat the blank to the appropriate temperature, forge it with forging equipment, improve the internal structure, and then perform shaping.

• Machining: First, rough machining to remove most of the excess, then fine machining such as fine turning and grinding, and finally drilling and milling.

• Heat treatment: Quenching to obtain martensitic structure to improve hardness and strength, then tempering to eliminate internal stress and adjust performance.

• Surface treatment: Nitriding or hard chrome plating can be performed to improve surface hardness, wear resistance and corrosion resistance.

• Quality inspection: Dimensional accuracy, surface quality, hardness are tested, and internal defects are detected with flaw detection equipment.

• Assembly and packaging: Clean qualified pins, assemble with related components, and then package according to needs.
