The Properties and Application Range of NM400 Steel

NM400 is a high-strength wear-resistant steel primarily used for components that require high wear resistance and impact resistance. Its excellent hardness and wear performance make it widely used in industries such as mining, metallurgy, and construction. The high hardness and impact resistance of NM400 make it an ideal material for equipment like stone crushers and buckets, excelling in high-wear environments.

In terms of chemical composition, NM400 contains higher levels of carbon, manganese, and silicon. The carbon content is typically around 0.30%, while manganese ranges from 1.0% to 1.5%, and silicon is used as a deoxidizing agent to enhance strength and wear resistance. Chromium and molybdenum may also be added to improve corrosion resistance. Due to these features, NM400 excels in components that require high wear resistance and corrosion resistance.

NM400 is commonly used in mining machinery, metallurgical equipment, construction machinery, and transportation equipment. It is particularly suitable for high-wear components like buckets, scrapers, bucket-wheel excavators, and scraper conveyors. By using NM400, the durability and production efficiency of equipment can be significantly improved, while maintenance costs are reduced.
