Hot Rolled Nm500 Hb500 Ar450 Nm450 Ar500 Spa-H Abrasion Anti Nm400 Wear Steel Sheets Resist Wear Resistant Stee
At present, the commonly hot rolled nm500 wearing resisting sheets hb500 domex400 ar500 spa-h abrasion hot rolled nm500 hb500 domex400 ar450 nm450 ar500 spa-h abrasion anti wear steel sheets resist wear resistant steel plate is a plate made of a common wear-resistant layer with high hardness and excellent wear resistance by a surfacing method on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity. product. In addition, there are cast wear-resistant steel plates and alloy hardened hot rolled nm500 hb500 domex400 ar450 nm450 ar500 spa-h abrasion anti wear steel sheets resist wear resistant steel plate.
| Excellent wear resistance The chemical composition of the wear-resistant layer of the alloy has a carbon content of 4 to 5%, a chromium content of 25 to 30%, a volume fraction of Cr7C3 carbide in the metallographic structure of 50% or more, a macrohardness of HRC of 56 to 62, and chromium carbide. The hardness is HV1400 to 1800. The wear resistance comparison with several typical materials is as follows: (1) with low carbon steel; 20 ~ 25: 1 (2) with as-cast high-chromium cast iron; 1.5 to 2.5:1 | |
| Good impact resistance The substrate of the wear-resistant composite steel plate is low carbon steel or low alloy. The toughness material such as stainless steel reflects the superiority of the bimetal. The wear layer resists the wear of the wear medium, and the substrate bears the load of the medium, so it has good impact resistance. Can withstand the impact and wear of high drop hoppers in material handling systems. | |
| Better heat resistance The wear-resistant layer of alloy is recommended to be used under the condition of ≤600 °C. If alloys such as vanadium and molybdenum are added to the wear-resistant layer of the alloy, it can withstand high temperature wear of ≤800 °C. Low-alloy heat-resistant steel sheets (15CrMo, 12Cr1MOV, etc.) substrates are recommended to be used not higher than 540 °C; Heat-resistant stainless steel substrates are recommended for use at temperatures not higher than 800 °C. | |
| Good corrosion resistance The alloy layer of the wear-resistant composite steel plate contains a high percentage of metal chromium, so it has certain rust and corrosion resistance. It can be used to prevent coal sticking when used in coal mining tanks and funnels. |
