What is wear-resistant steel plate? Wear Resistant Steel Plate refers to a special plate product specially designed for use under large-area wear conditions. At present, commonly used wear-resistant steel plates are made by surfacing a certain thickness of alloy wear-resistant layer with higher hardness and excellent wear resistance on the surface of ordinary low carbon steel or low alloy steel with good toughness and plasticity through welding method. product. In addition, there are cast wear-resistant steel plates and alloy quenched wear-resistant steel plates.
Wear-resistant plates generally include 3+3, 4+2, 5+3, 5+4, 6+4, 6+5, 6+6, 8+4, 8+5, 8+6, 10+5, 10 +6, 10+8, 10+10, 20+20, etc.
Commonly used welding wire models for wear-resistant plates: LZ570, LZ590, LZ601, LZ606, LZ650, etc. (Welding wire diameter: 2.4-3.2)
Properties of AR steel plate, sheet & coil vary depending on the grade. The lower the grade, such as AR400, the more formable the steel is. The higher the grade, like AR500, the harder the steel is. AR450 is right in the middle, denoting a "sweet spot" between hardness and formability.
GRADE |
HARDNESS BRINELL |
| AR200 | 170-250 BHN |
| AR400 | 360-444 BHN |
| AR450 | 420-470 BHN |
| AR500 | 477-534 BHN |
What are the grades of wear-resistant steel plates? Wear-resistant steel plates are currently the main industrial wear-resistant materials. To facilitate engineers' selection, the main wear-resistant steel plate grades are now classified according to country as follows:
China (Wugang, New Steel, Wuhan Iron and Steel, Nanjing Iron and Steel, Baosteel, Naimo Technology): NM360, NM400, NM450, NM500, NR360, NR400, B-HARD360, B-HARD400, B-HARD450, KN-55, KN- 60.KN-63
Swedish Wear Carbon Steel Plate: NM400, NM450, NM500, NM600, SB-50, SB-45
