What is wear-resistant steel plate?
Wear-resistant steel plate refers to a specialized plate product designed for use in conditions subject to extensive wear. Currently, commonly used wear-resistant steel plate is manufactured by applying a thick, hard, and wear-resistant alloy wear-resistant layer to the surface of ordinary low-carbon or low-alloy steel, which exhibits good toughness and ductility, through a cladding process. Other types of wear-resistant steel plates include cast wear-resistant steel plates and alloy-hardened wear-resistant steel plates.
In industrial manufacturing, the choice of wear-resistant steel plate directly impacts equipment lifespan and operating efficiency. Many people assume that harder steel plates are better, but this is not the case. Different materials are suitable for different working conditions. For example, 65Mn manganese steel plate offers excellent elasticity and wear resistance, making it suitable for use in applications with high impact loads. High-strength wear-resistant steel plates such as NM400 and NM450 are more suitable for high-wear environments, particularly in mining and construction machinery.
Differences Between NM400 and NM500 Wear-Resistant Plates
NM400 and NM500 are two common types of wear-resistant steel plates. Their main differences are as follows:
- Hardness
- The Brinell hardness of NM400 wear-resistant steel plate is typically between 360 and 440 HBW.
- The Brinell hardness of NM500 wear-resistant steel plate is typically between 470 and 530 HBW. NM500's significantly higher hardness than NM400 gives it a greater advantage in terms of wear resistance and allows it to withstand greater friction and impact.
- Mechanical Properties
- In terms of strength, the yield strength of NM400 is typically above 800 MPa, and the tensile strength can reach approximately 1000 to 1200 MPa.
- The yield strength of NM500 is typically above 1000 MPa, and the tensile strength can reach approximately 1200 to 1400 MPa. NM500 has higher strength and can withstand greater external forces and impacts, making it more suitable for use in high-load and high-wear working environments.
- Wear Resistance
Due to differences in hardness and strength, NM500 exhibits superior wear resistance to NM400. In practical applications, NM500 wear-resistant steel plate is suitable for applications with more severe wear conditions, such as equipment components subjected to long-term, severe wear in industries like mining, cement manufacturing, and port loading and unloading.
NM400, on the other hand, is suitable for applications with less severe wear or more cost-sensitive requirements, such as wear-resistant components in general engineering and construction machinery.
- Processing Performance
NM400 has a relatively low hardness and is relatively easy to process. It can be formed into various shapes through cutting, welding, bending, and other processing methods, resulting in relatively low processing costs.
NM500, due to its higher hardness, is more difficult to process, requiring higher requirements for processing equipment and processes. This requires specialized tools and process parameters, resulting in increased processing costs.
- Applications
NM400 wear-resistant steel plate is widely used in construction machinery, mining machinery, environmental protection machinery, coal mining machinery, and other fields. For example, in applications such as excavator buckets, loader blades, and crusher liners, NM400 can meet wear resistance requirements to a certain extent while also balancing cost and processability.
NM500 wear-resistant steel plate is primarily used in applications requiring extremely high wear resistance, such as mine chutes, crusher hammers, cement mill liners, and port grabs. In these environments, equipment is subject to severe wear, and NM500's high wear resistance effectively extends equipment life and reduces repair and replacement costs.
