Production Introduction
What are wear-resistant aluminum alloy steel plates?
1, there are kn60, nm360, or nm400, nm500, nm550 and other models. Choose kn60 model, the carbonization hardness is very high, and the service life can reach more than 10 times that of ordinary steel plate. Because the chromium content in it is relatively high, the wear resistance will be more prominent, and the wear resistance of the plate itself is relatively high.
2, their thickness is large and small, such as thin can reach 3 mm. The thickness can reach 150 mm, and the width size also has a lot of room to choose from between 1500 mm and 2200 mm.
Specific brand: According to the search results, The specific grades of wear-resistant alloy steel also include HARDOX400, HARDOX450, HARDOX500, HARDOX600, SB-50, SB-45, XAR400, XAR450, XAR500, XAR600, Dillidur400, Dillidur500, QUARD400, QUARD45 0, QUARD500, FORA400, FORA500, Creusabro4800, Creusabro8000, RAEX400, RAEX450, RAEX500, JFE-EH360, JFE-EH400, JFE-EH500, WEL-HARD400 WEL-HARD500, KN-55, KN-60, KN-63, etc
Specifications and Application
The series of Abrasion wear-resistant steel combined the properties including high strength, high hardness, high wear resistant, weldable, bendable and mainly applied in:
- Edge of loaders in loader industry
- Wear-resistant lining plate in crusher industry.
- Slat type conveyer in colliery mechanical industry.
- Lining plate of coal pulverizer in power industry.
- Lining plate of hopper for heavy handling truck.
