1. Introduction to WNM400 grade:
The letter w is the capitalization of the first letter of the Chinese pinyin character "dance" that represents Wugang; The letter n is the first letter of the word "resistant" in Chinese pinyin, which means wear-resistant; The letter M is the first letter of the word "grinding" that means wear-resistant, and the first letter of the Chinese pinyin is capitalized; The number 400 is the Brinell hardness value Hb value.
Second, the introduction of WNM400 steel plate.
The manufacturer of this steel plate is Wuyang Iron and Steel, and the delivery state is quenched and tempered. It has high strength and wear resistance, good machinability, excellent welding performance and corrosion resistance. It is widely used in various structural parts and parts such as mechanical equipment, vehicles, ships, bridges, etc., which require high strength and wear resistance.
WNM400 steel plate implementation standard: Q WTB012-2010WJX030-2010 (Wugang enterprise standard).
WNM400 steel plate manufacturing method: electric furnace + external refining and smelting.
WNM400 steel plate delivery status: quenched and tempered (quenched + tempered) state.
WNM400 steel plate can be produced thickness: 8--100mm
3. Chemical composition of WNM400 steel plate:
4. Mechanical properties of WNM400 steel plate:
5. WNM400 steel plate production process:
Smelting: Smelting is carried out by electric furnace + external refining to ensure that the composition and temperature of molten steel meet the requirements.
Continuous casting: The smelted molten steel is continuously poured into billet and slowly cooled.
Rolling: The continuously cast billet is heated and rolled in multiple passes to make it a high-strength wear-resistant steel plate with the required thickness, width and length.
Heat treatment: According to the process requirements, the rolled steel plate is quenched and tempered by quenching + tempering to obtain the required mechanical properties.
Surface treatment: The surface of the steel plate is treated with shot blasting, painting or plastic spraying to improve its corrosion resistance and aesthetics.
6. WNM400 steel plate application and equipment:
WNM400 steel plate is used in mining machinery to manufacture wear-resistant and wearing parts, such as working devices and blades for excavators, loaders, bulldozers, etc.; It is suitable for wear-resistant parts in coal mining machinery, such as conveyor belts, scrapers, shearers, etc.; In construction machinery, it can be used to manufacture structural parts and wear-resistant parts, such as cranes, pump trucks, mixing plants, etc.
