>> Premium Materials for Durability and Strength

• Core Material

• - High-grade Alloy Steel

• - Common base materials include 4140 or Cr-Mo alloy steels such as 42CrMo/35CrMo (Chromoly steel); these are the standard choices for pins and shafts in heavy construction machinery.

• - These steel grades possess excellent strength, toughness, and fatigue resistance, making them suitable for operating conditions involving heavy loads, impact forces, and repetitive bending stresses.

• Heat Treatment and Hardness

• -Induction Hardened: The surface undergoes a high-frequency induction hardening process.

• - Surface hardness typically reaches a minimum of HRC 56 (with a hardened layer depth of approximately 1 mm or greater).

• - The core hardness is maintained at approximately HRC 22–25, ensuring overall toughness (thereby preventing brittle fracture).

• - This treatment method significantly enhances wear resistance, scratch resistance, and service life, while the core retains sufficient impact toughness.

• Surface Treatment

• - Chrome Plated / Chromed: The outer surface is typically coated with a thin layer of chrome (approximately 0.02–0.03 mm in thickness).

• - Function: To further improve corrosion resistance and oxidation resistance, reduce the coefficient of friction, and enhance surface finish.

• Key Features Summary

• - Material Combination:Alloy steels (e.g., 4140 / 42CrMo) + Induction Hardening + Chrome Plating.

• -Design Purpose: To provide exceptional wear resistance, impact resistance, and corrosion resistance in high-wear, high-load applications—such as loader bucket linkages and hydraulic cylinder pin eyes—thereby extending replacement intervals.
