What material is nm400

    
    NM400 is a high wear-resistant steel with a hardness of 400 HBW (hardness level of Brinell) and a thickness of 16 mm. It was developed by Nippon Steel Corporation and its trademark is NM400. It is an abrasion-resistant steel with a high level of hardness, excellent cold forming properties, and high toughness.
    
    NM400 is a wear-resistant steel with excellent performance. It has 5-8 times the strength of general structural steel and can withstand extremely high impact loads. Therefore, it has a much longer service life compared to mild steel. It is also very resistant to abrasion and corrosion. It can also resist debris and other high-speed particles, which makes it ideal for applications that require high wear-resistance and toughness.
    
    The steel is suitable for production of parts and components that require very high wear-resistance and excellent surface finish. It has been widely used in many industries, such as construction, transport, agriculture, and manufacturing. It is also used to manufacture tools and drilling rigs.
    
    NM400 offers a wide range of advantages over mild steel, such as high strength and resistance to impact, excellent corrosion-resistance, and high wear-resistance. It is also heat-treated for increased durability. It is becoming increasingly popular because of its superior properties, and is often used in place of mild steel for applications that require high strength and toughness.
