Wear Resistant Alloys

Today, due to higher performance of equipments and products , more machines are operated in higher speed and higher pressure, and under heat and corrosion resistant conditions. On the other hand, users' demands are becoming more diversified and sophisticated with regard to wear and abrasion, requiring products with longer life cycle, maintenance-free, and reduction of noise caused by detrition , etc..

Based on accumulated technology and various wear resistance data that extend over 40 years on manufacturing and processing of wear-resistant alloys, MMC Superalloy manufactures various wear-resistant alloys and alloy powders, while giving advises and offering various services.

The following list, for reference, is a comprehensive introduction of the various types of alloys regarding wear-resistant alloy. Please note that each data is an average value based on experimental data, and is not a guaranteed value.
