Key Benefits
Mn13 / X120Mn12 / Mn12 (High-Manganese Austenitic Series) - Work-hardening capability increases surface hardness under repeated impact while maintaining a tough core, making it ideal for buyers needing long service life in heavy impact applications.
NM400 / NM450 / NM500 / NM550 / NM600 (Standard Q&T Series) - Progressive hardness levels from 400 to 600 HBW allow buyers to balance wear resistance, formability, and service life for different abrasion conditions.
NM400Tuf / NM450Tuf / NM500Tuf (High-Toughness "Tuf" Series) - Enhanced impact toughness maintains the same hardness as standard Q&T grades while significantly improving crack resistance in severe impact environments.
NM450SP (Super Wear-Resistant Series) - Optimized wear resistance beyond conventional NM450 extends maintenance intervals for equipment exposed to continuous sliding abrasion.
NMS450-1 / NMS450-2 (Wear & Corrosion Resistant Series) - Combined abrasion and corrosion resistance helps reduce material replacement in wet, acidic, or chloride-containing operating environments.
NM450HiTemp (High-Temperature Wear Series) - Stable hardness at elevated operating temperatures provides longer wear life where conventional wear plates soften under heat.
NM300TP (Concrete Mixer Drum Series) - Controlled hardness with excellent forming performance enables efficient drum manufacturing while improving resistance to concrete abrasion.
