NM400 steel plate is a high-strength, wear-resistant steel plate widely used in industries requiring a combination of strength, toughness, and abrasion resistance. This article delves into the properties, applications, and benefits of NM400 steel plates, providing a comprehensive understanding of why they are the material of choice for many demanding environments.
What is NM400 Steel?
NM400 is a wear-resistant steel grade with a nominal hardness of 400 HBW. It combines high wear resistance with good welding properties, making it suitable for applications requiring durability and resistance to wear and tear. The “NM” in NM400 stands for “wear-resistant” in Chinese (Nai Mo), indicating its primary function.
Properties of NM400 Steel
- High Hardness: The primary feature of NM400 steel is its high hardness, typically around 400 HBW, significantly improving its wear resistance.
- Strength: NM400 has high tensile strength, making it capable of withstanding heavy loads and impacts without deformation.
- Toughness: Despite its hardness, NM400 steel retains good toughness, essential for resisting crack formation and propagation.
- Good Weldability: NM400 steel can be welded using standard welding techniques, ensuring it can be incorporated into various structures without compromising its properties.
- Formability: It can be cut and formed into different shapes and sizes, making it versatile for various applications.
