NM400 wear-resistant steel plates, NM450 wear-resistant steel plates, and NM500 wear-resistant steel plates are all high-strength wear-resistant steel plates with high wear resistance. Wear-resistant steels NM450 plate price per ton are widely used in mining machinery, coal mining and transportation, construction machinery, and agricultural machinery, building materials, electric machinery, railway transportation and other industries.
The company operates Henan metallurgical rolling iron and steel factory all year round, providing steel products for various industries such as ow alloy high strength series, boiler and pressure vessel steel plate, power station engineering steel plate series, NM450 plate price per ton bridge structure steel plate, corrosion resistant steel plate, composite steel plate, high-rise building structure, die steel plate series, steel plate series for shipbuilding and offshore platforms, pipeline steel plate, alloy structure and other steel plates.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality NM450 plate price per ton products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
Both the cross rolling method and the extrusion method must first heat the tube blank or ingot, and the steel tube produced is called hot rolling tube. Steel pipes produced by hot working can sometimes be cold worked as required. There are two methods of cold working: one is cold drawing, that is, drawing the NM450 plate price per ton steel pipe through the drawing die to make the steel pipe gradually thin and elongate; the other is cold rolling, which is the method of applying the hot rolling mill invented by the menesmann brothers to cold working. The cold working of NM450 plate price per ton seamless steel pipe can improve the size accuracy and finish of steel pipe, and improve the mechanical properties of materials.
