Abrasion -resistant steel is a dedicated steel.There are many types of wear -resistant steel. Due to the different chemical composition, thermal treatment and hardness of wear -resistant steel, its source is very convenient and excellent.Agricultural machinery, various building materials, power machinery, railway transportation and coal collection and other departments.
Wear -resistant steel welding process
Determination of the welding process 1. Welded the slopes. Due to the high requirements of the slopes, all of the ramp making production is completed by mechanical processing, and it is required to prohibit impurities such as water, oil, and rust on both sides of the slopes.2. The selected welding material should be comparable to the intensity of the welded material, and the welding wire is protected by a mixed gas. The welded wire uses GHS -70 high -strength welding wire, and the diameter of the welding wire is 1.6mm.3. Possented the wealthy protection welding, and the DC reverse is connected.4. Preheating before welding, the preheating temperature adopted according to the mechanical properties of the NM360 is 120 ° C ~ 150 ° C, and the oxygen -acetylene gas (or NAS gas) is used in the near welding area.High, otherwise the high temperature stay time will be increased to slow down the cooling speed and promote crispy cracks.5. Use hybrid gas protection welding and use AR+CO2 hybrid gas protection welding. Among them, AR is 70%~ 80%, and CO2 is 20%to 30%.
Wear -resistant steel price
Product unit price: 3000.00 yuan/ton 1, wear-resistant steel ball specifications: φ10mm-φ130mm; 2. wear-resistant steel ball chromium content (CR10.0%-28.0%), hardness (HRC58-68), impact value (≥3.5)Quality standards such as J/CM2), crushing rate (≤0.3%) are tailor -made or contract agreement according to the actual conditions of the user.
Wear -resistant steel
Wear -resistant steel is widely used in mining machinery, coal collection, construction machinery, agricultural machinery, building materials, power machinery, railway transportation and other departments.For example, the steel balls, lining plates, excavators of the ball mill, the fighting teeth, fighting buckets, the rolling wall, tooth plate, hammer head, tractor and fan grinding machine, railway railway, railway railway, railway grinding board, tractor and tankFork, the middle slot, gangblone, ring chain of the coal mines scraper conveyor, shovel, shovel teeth, large electric wheels buckets, oil and open -air iron ore piercing drills, etc.Essence
Wear -resistant steel type
1. The cast state tissue of high manganese steel and high manganese steel is usually composed of Austenitic, carbides and pearls, and sometimes contains a small amount of phosphorus crystals.When the number of carbides is large, it often appears in the crystal world.Therefore, the high manganese steel of the cast state is crispy and cannot be used. It needs to be soluble.The commonly used thermal treatment method is solid -soluble treatment. The steel will be heated to 1050 ~ 1100 ° C to eliminate the cast state tissue, get a single -phase Aolinth tissue, and then water to quench, so that such tissues are kept to normal temperature.The strength, plasticity and toughness of the steel after thermal treatment are greatly improved.
