NM450 Wear Resistant Sheet

NM450 wear-resistant sheet is made by refining steel with a high-temperature treatment process and then adding alloying elements such as chromium and manganese to improve its durability and strength. The sheet is typically used in heavy-duty equipment where harsh working conditions cause wear and tear. Some common applications of NM450 wear-resistant sheet include mining machinery, construction equipment, and agricultural machinery. With its ability to withstand heavy physical impact and wear, NM450 wear-resistant steel sheet is an ideal choice for demanding industrial applications.

The chemical elements present in NM450 wear-resistant sheet are:

- Carbon (C): 0.35%

- Silicon (Si): 0.70%

- Manganese (Mn): 1.70%

- Phosphorus (P): 0.025%

- Sulfur (S): 0.010%

- Chromium (Cr): 1.50%

- Nickel (Ni): 1.50%

- Molybdenum (Mo): 0.50%

- Vanadium (V): 0.06%

NM450 wear-resistant sheet quality inspection involves a series of tests to ensure that the product meets the specified requirements and performs well in its intended applications. The inspection process typically consists of the following steps:

1. Visual Inspection: The first step is a visual inspection to ensure that the product has no defects, such as cracks, porosity, or surface irregularities.

2. Hardness Testing: The hardness of the material is tested using a Brinell or Rockwell hardness tester to ensure that it meets the specified requirements.

3. Chemical Composition Analysis: The chemical composition of the material is analyzed to ensure that it meets the specified requirements. This is typically done using spectroscopy or chemical analysis techniques.

4. Microstructure Examination: The microstructure of the material is examined using a microscope to ensure that it does not have any defects or impurities that could affect its performance.

5. Mechanical Property Testing: Various mechanical properties of the material, such as strength, toughness, and fatigue resistance, are tested to ensure that it can withstand the intended applications.

6. Surface Inclusion Testing: This involves checking the surface of the material for any inclusions or foreign particles that could cause cracks or other defects.

7. Dimensional Inspection: The dimensions of the material are checked to ensure that they meet the specified requirements.
