Non-destructive flaw detection of steel plates is a test method for inspecting the hot rolled NM450 wear resistant sheet surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used hot rolled NM450 wear resistant sheet 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.
The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable hot rolled NM450 wear resistant sheet steel products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the market and has strong competitiveness.
For the hot rolled NM450 wear resistant sheet construction industry, the largest consumer sector of the steel industry and the least affected industry in the EU this year, it is estimated that hot rolled NM450 wear resistant sheet steel consumption will account for 35% of the EU steel consumption market this year. Uestf forecasts that the output of the construction industry will decline by 5.3% in 2020 and rise by 4% in 2021.
Advantages of NM360 wear-resistant steel plate: NM360 steel has high strength: generally its yield strength is above 300MPa. 2. High toughness: The elongation is required to be 15% -20%, and the room temperature impact toughness is greater than 600kJ / m ~ 800kJ / m. For large welded components, high fracture toughness is also required. 3. NM360 steel plate has good welding performance and cold forming performance. 4. Low cold and brittle transition temperature.
