Technical Specifications
Product Overview
Metallurgical Composition and Structure
NM600 Extreme is a low-alloy, high-carbon martensitic steel engineered for maximum wear resistance. The carefully balanced chemical composition featuring 0.47-0.54% carbon, combined with chromium, molybdenum, and boron additions, creates a fine martensitic microstructure with exceptional hardness uniformity. The controlled addition of nickel enhances toughness while maintaining ultra-high surface hardness.
Advanced Heat Treatment Process
MetalZenith employs a sophisticated quenching and tempering process utilizing controlled atmosphere furnaces and precision cooling systems. The steel is austenitized at 880-920°C, followed by accelerated cooling to achieve complete martensitic transformation. Subsequent tempering at 180-220°C optimizes the balance between hardness retention and impact resistance, ensuring consistent 570-640 HBW hardness throughout the plate thickness.
Manufacturing Excellence and Quality Control
Our integrated steel production facility features electric arc furnaces with advanced secondary metallurgy, continuous casting technology, and state-of-the-art rolling mills. Real-time process monitoring ensures precise chemical composition control and optimal mechanical properties. Comprehensive quality assurance includes spectroscopic analysis, automated hardness mapping, ultrasonic testing for internal soundness, and dimensional verification using laser measurement systems.
International Standards Compliance
NM600 Extreme meets stringent international standards including EN 10204 for inspection documents, ASTM A514 for structural applications, and JIS G3106 for welded structures. Our ISO 9001:2015 certified quality management system ensures consistent product quality and full traceability from raw materials through final delivery. All products are supplied with comprehensive mill test certificates documenting chemical composition, mechanical properties, and dimensional compliance.
