On June 7, a new batch of 300 tons of high-end wear-resistant steel NM500-DBJ customized and developed by Handan Iron and Steel Company of HBIS Group was delivered to a large domestic engineering machinery manufacturing company. The product has excellent bending performance, welding performance, and wear resistance, and the quality fully meets the customer's high standards. This product will replace imports and be used in the manufacture of key parts of high-end hydraulic balers. At present, Handan Iron and Steel has continuously supplied more than 2,000 tons to this customer.
The high-end hydraulic baler produced by this customer is used for cutting, crushing, compressing, and baling scrap steel. To ensure good crushing and compression performance and the long service life of the baler, the steel needs to be bent 90 degrees three times and then welded with gas shielding multiple times. Hence, the material bending and welding performance requirements are extremely stringent.
Handan Steel has been deeply promoting the optimization of the "two structures", targeting the demand for high-end wear-resistant materials in key industries at home and abroad, continuously increasing follow-up and visit efforts, giving full play to its technical marketing advantages, deepening EVI full-process services, creating domestically launched "single champion" products that replace imports, and further enhancing the brand influence of wear-resistant steel.Handan Steel's wear-resistant steel technical marketing team conducted special technical exchanges with customers, introduced and demonstrated the excellent performance of Handan Iron and Steel's wear-resistant steel products, provided a full range of material solutions, won the trust of customers, and signed contracts. Technical R&D personnel optimized the product composition design and process plan formulation, strictly confirmed the quality of raw materials and equipment accuracy before production, implemented the high-draw carbon supplementary blowing mode in the converter of the steelmaking process, operated the entire smelting process by the nitrogen control mode, optimized the use of protective slag, and put into use electromagnetic stirring equipment. In particular, the innovative heat treatment process adopts a lower austenitizing insulation temperature, a temperature-controlled quenching process, and a three-stage quenching and cooling process, and strengthens the control of key process parameters to improve the wear resistance of the entire plate. After the product was delivered, it was highly recognized by customers.
