NM450 Grade equivalent

    
    The new steel grade NM450 is an advancement on the existing NM400 grade steel. This grade is a hot rolled steel, which is heat treated and wear resistant. It has a high yield strength, excellent weldability, and excellent formability. It is suitable for applications such as shafts, axles, and general engineering components.
    
    NM450 is an advanced high strength steel which has been developed specifically for weldable applications. This grade has higher yield strength than traditional mild steels, allowing for parts to withstand higher loads and stresses. It is a very tough steel, with excellent toughness, fatigue, and wear resistance properties. Its tensile strength of between 670-1120 MPa (mega-pascals) is ideal for a range of engineering applications. It is also formable, providing users with customization options.
    
    NM450 has a good yield strength of 630-660 MPa and has excellent weldability and formability for fabrication. In addition, it has an improved resistance to temperature-dependent cracking which makes it suitable for high temperature applications. It has an impressive tensile and yield strength, combined with an exceptional fatigue strength. The properties of this steel grade make it ideal for applications such as mining machinery, vehicle construction, tools, and bridges.
    
    NM450 is a versatile and cost-effective material that is widely used in a range of engineering applications. It is suitable for a variety of uses thanks to its high fatigue strength, wear resistance, and weldability. It also has a good workability and formability, making it suitable for fabrication as well. As such, NM450 is an ideal material for constructing heavy-duty structures such as bridges and ship hulls.
    
    Overall, NM450 grade steel is an advanced high-grade steel which is suitable for a wide range of applications, building on the foundation set by NM400 grade steel. It has good welding, forming, and cutting properties, making it a popular choice for many engineering jobs. It also has high yield, fatigue, and wear resistance making it suitable for heavy duty applications such as load bearing structures. Finally, despite its impressive toughness and strength, this grade of steel is still cost-effective and easy to work with.
