Our unique technology enhances the wear and corrosion resistance of stainless steel, which was not achievable with conventional methods.
Not a surface treatment like coating ☆★Introduction to Special Hardening Treatment☆★ Key features include: ● Improved surface hardness ● Enhanced corrosion resistance ● Increased fatigue strength ● Improved galling resistance ☆☆Expanite Low-T☆☆ This is a low-temperature treatment process using nitrogen and carbon gases. It significantly improves surface hardness (1200HV) and wear resistance, and also enhances corrosion resistance. ☆☆Expanite High-T☆☆ This is a high-temperature treatment process using nitrogen gas. It greatly improves corrosion resistance and also increases surface hardness (750HV). Additionally, it enhances wear resistance. ☆☆Super Expanite☆☆ A hybrid process combining Expanite High-T and Expanite Low-T. This process takes the best aspects of each treatment to significantly improve corrosion resistance, surface hardness, and wear resistance. Expanite treatment offers optimal processes tailored to the user's applications and objectives. Please check the detailed materials that can be treated after downloading.
