Household Hot Rolled Wear Resistant Steel Plate NM360 NM400 NM450 NM500

1. Excellent wear resistanceThe chemical composition of the alloy wear-resistant layer is 4-5% carbon content and 25-30% chromium content. The volume fraction of Cr7C3 carbides in the metallographic structure is greater than 50%. The macro hardness is HRC56～62, and the hardness is HV1400～1800. Due to the vertical distribution of carbides along the wear direction, the wear resistance is more than doubled even compared to cast alloys of the same composition and hardness. The wear resistance comparison with several typical materials is as follows: (1) Low carbon steel; 20～25:1 (2) As-cast high chromium cast iron; 1.5～2.5:12. Good impact resistanceThe bottom plate of wear-resistant composite steel plate is low carbon steel or low alloy. Tough materials such as stainless steel embody the superiority of bimetals. The wear-resistant 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 conveying systems.3. Good heat resistanceThe alloy wear-resistant layer is recommended to be used under ≤600℃. If vanadium, molybdenum and other alloys are added to the alloy wear-resistant layer, it can withstand high temperature wear of ≤800℃. The recommended operating temperature is as follows: It is recommended to use the ordinary carbon steel base plate under the working condition of not higher than 380℃; The base material of low alloy heat-resistant steel plate (15CrMo, 12Cr1MOV, etc.) is recommended to be used under the working condition of not higher than 540℃; Stainless steel substrates are recommended for use at temperatures up to 800°C.4. Good corrosion resistanceThe alloy layer of the wear-resistant clad steel plate contains a relatively high proportion of metallic chromium, so it has a certain anti-rust and anti-corrosion ability. When used in coal drop buckets and coal drop buckets, it can prevent coal from sticking.5. Complete varieties and specificationsThe wear-resistant steel plate has complete specifications and varieties, and has been commercialized and serialized. The thickness of the wear-resistant alloy layer is 3-20mm. The thickness of the composite steel plate is at least 6mm, and the thickness is not limited. Standard wear-resistant steel plate can provide 1200 or 3800 × 12000mm, and can also be processed according to the size of the drawing according to user needs. Wear-resistant steel plates are now divided into three types: ordinary type, impact-resistant type and high-temperature type. When ordering high temperature wear-resistant and impact-resistant composite steel plate, it should be stated.6. Convenient processing performanceWear-resistant steel plates can be cut, bent or crimped, welded and punched, and can be processed into various parts that ordinary steel plates can process. The cut wear-resistant steel plate can be tailor-welded into various engineering structural parts or parts.7. Functions and FeaturesWeldable, good wear resistance.
