Description
NM600 Wear Resistance Steel Plate
NM600 Wear Resistance Steel Plate is a high-strength, abrasion-resistant steel designed for extreme durability in demanding industrial applications. With a Brinell hardness of approximately 570-640 HBW, this steel plate offers exceptional resistance to wear, impact, and high temperatures, making it ideal for heavy-duty environments such as mining, construction, and material handling. Engineered with a unique alloy composition and advanced heat treatment, NM600 ensures prolonged equipment life, reduced maintenance costs, and enhanced operational efficiency.
Key Features
- Superior Wear Resistance: The alloy wear-resistant layer, with 4-5% carbon and 25-30% chromium, provides wear resistance over twice that of cast alloys with similar composition, thanks to vertically distributed carbides.
- High Impact Toughness: The low-carbon or low-alloy steel base ensures excellent impact resistance, capable of withstanding high-drop hoppers and heavy loads in material conveying systems.
- Temperature Resilience: Suitable for use in conditions up to 600°C, with customized options for temperatures up to 800°C when alloyed with vanadium or molybdenum.
- Versatile Processing: Offers good weldability (with preheating to 150-200°C) and cold-bending capabilities, allowing for flexible machining, forming, and connection methods like welding and bolting.
- High Hardness: Achieves HV1400-1800 hardness, ensuring exceptional durability in abrasive environments.
- Quality Assurance: Manufactured under ISO 9001:2015 standards with rigorous testing, including chemical analysis, hardness mapping, and ultrasonic inspection, ensuring consistent quality and traceability.
