wear-resistance of nm500 technical parameters

After adding phosphorus, copper, chromium, nickel and other trace elements to the steel, a dense and highly adherent protective film is formed on the surface of the steel, which hinders the spread and development of rust and protects the substrate under the rust layer to slow down its corrosion rate. The amorphous spinel-type oxide layer with a thickness of about 50μm-100μm formed between the rust layer and the substrate is dense and has good adhesion to the substrate metal.

The wear-resistant layer of wear-resistance of NM500 wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy wear-resistance of NM500 carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

Non-destructive flaw detection of steel plates is a test method for inspecting the wear-resistance of NM500 surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used wear-resistance of NM500 steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
