1, WNM550A Details:
WNM550A "W" is the symbol of Wugang brand. "NM" refers to the wear-resistant plate, the first letter of the word "resistant" and "grinding". W "means Wuyang Iron and Steel Co., LTD." dance "Chinese pinyin the first letter of the word, this brand belongs to the Wugang advanced quality control type wear-resistant plate. Its representative level is higher than WNM360,WNM400 and WNM450. Usually seen in WNM550A/B, the value A indicates that no impact is done, and the value B represents that the impact is done at room temperature 20°.
2, WNM550A delivery status: tempering (quenching + tempering) PS: If the customer needs other special delivery status should be indicated in the contract.
3, tempered steel:
Medium carbon or low carbon structural steel is first cleaned and then tempered at high temperature to obtain higher strength and impact toughness and other better comprehensive mechanical properties of steel.
4, excellent wear resistance: the chemical composition of the alloy wear-resistant layer of carbon content of 4 ~ 5%, chromium content of 25 ~ 30%, the volume fraction of Cr7C3 carbide in the metallographic structure of more than 50%, the macro hardness of HRC56 ~ 62, the hardness of chromium carbide is HV1400 ~ 1800. Because the carbide is vertically distributed in the wear direction, the wear resistance is more than doubled compared with the cast alloy with the same composition and hardness.
5, good impact resistance: the substrate of wear-resistant composite steel plate is low carbon steel or low alloy. Stainless steel and other ductile materials, reflecting the advantages of bimetal, wear-resistant layer to wear the wear of the medium, the substrate bears the load of the medium, so it has good impact resistance. Can withstand impact and wear such as high drop hoppers in material handling systems.
6, WNM550A steel plate standard: the rest of the steel plate size, shape, weight and allowable deviation should conform to GB/T709
7, WNM550A packaging, marking, quality certificate: steel packaging, marking, quality certificate should comply with GB/T 247 provisions.
8, WNM550A steel plate use:
Because the high-strength wear-resistant steel plate, especially has a high wear resistance, Brinell hardness value of 550 (HBW), mainly provides protection in wear-resistant occasions or parts, so that the equipment life is longer, reduce the maintenance and downtime brought by maintenance, and correspondingly reduce the investment of funds. Mainly used in mining, coal mine, environmental protection, ventilation equipment, dump trucks and various construction machinery with wear-resistant parts processing and manufacturing of structural steel plates. Wugang brand wear-resistant plate has strong comprehensive performance, suitable for a variety of complex and difficult projects.
9. WNM550A application prospect:
WNM550A steel Wugang with its unique production process and advanced mechanical equipment will be perfect in front of everyone's eyes, its performance is also obvious. Construction machinery, mining machinery, coal mining machinery, environmental protection machinery, metallurgical machinery and other manufacturing enterprises for excavators, loaders, bulldozers bucket plate, edge plate, side edge plate, blade, crusher lining plate, blade construction projects of WNM550 steel plate about 5000 tons. In the export of the United States, Canada, Australia, India, Europe is a promising prospect. Has directly supplied more than 20,000 tons to European customers. The future is promising.
