NM450 is a premium wear-resistant steel plate with a Brinell hardness rating of 450 HBW, designed for superior performance in abrasive environments. Known for its high hardness, abrasion resistance, and impact strength, NM450 plates are widely used in fabrication, construction, and mining industries.
Brinell Hardness: 450 HBW for exceptional resistance to wear and abrasion
Excellent Weldability: Can be welded with standard techniques for easy fabrication
High-Temperature Performance: Maintains mechanical properties even under elevated temperatures
Corrosion & Oxidation Resistance: Performs reliably in both reducing and oxidizing environments
Good Formability: Can be cut, bent, and formed without compromising structural integrity
NM450 steel plates are ideal for heavy-duty equipment and high-wear applications, including:
Excavator buckets and dump trucks
Conveyor systems and crushers
Charging cranes and material handling machinery
Demolition tools, cutting blades, and waste recycling equipment
Compared to standard carbon steel plates, NM450 wear plates offer significantly improved wear life and impact resistance, reducing maintenance costs and improving operational efficiency.
To ensure the reliability and performance of NM450 steel, each batch undergoes strict quality control, including:
Positive Material Identification (PMI)
Intergranular Corrosion (IGC) Test
Mechanical and Hardness Testing
Chemical Composition Analysis
Pitting and Corrosion Resistance Tests
We also offer third-party inspection services for complete quality verification and customer peace of mind.
