NM400 steel is a high-strength, wear-resistant steel grade with exceptional hardness and toughness. Here are the key properties of NM400 steel:
Hardness: NM400 steel typically has a hardness range of 360 to 440 HBW (Brinell Hardness), which indicates its resistance to indentation, abrasion, and wear. The high hardness makes it suitable for applications involving sliding or impact abrasive wear.
Yield Strength: NM400 steel exhibits a minimum yield strength of 1000 MPa (megapascals). This high yield strength indicates its ability to resist deformation or plasticity under applied loads, contributing to its structural integrity and durability.
Tensile Strength: NM400 steel typically has a tensile strength of approximately 1250 MPa. The high tensile strength ensures the material's ability to withstand heavy loads and provides excellent resistance to mechanical stresses.
Impact Resistance: NM400 steel possesses good toughness and impact resistance, allowing it to withstand sudden shocks or impacts without brittle fracture. This property is crucial in applications where the material is subjected to dynamic loading or impact forces.
Wear Resistance: NM400 steel is specifically designed to offer exceptional wear resistance. It resists surface wear caused by contact with hard particles, ensuring prolonged service life and reducing the need for frequent maintenance.
Weldability: NM400 steel is weldable using conventional welding techniques. However, it is important to follow appropriate welding procedures and use compatible consumables to maintain the material's properties and performance during the welding process.
Formability: NM400 steel retains reasonable formability despite its high hardness and wear resistance. It can be shaped, bent, and formed into various complex geometries using standard fabrication techniques.
NM400 steel is commonly utilized in industries such as mining, construction, agriculture, and earthmoving equipment, where components are subjected to severe abrasive wear conditions. It offers a cost-effective solution for extending the service life of machinery and equipment, reducing downtime, and improving productivity.
It's worth noting that the specific properties of NM400 steel may vary slightly depending on the manufacturer and production processes. Consulting suppliers or manufacturers can provide more precise information on the properties and capabilities of NM400 steel for your specific application.
