Global nm500 grade material demand will shrink

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and NM500 grade material pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

Hot rolled NM500 grade material steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the NM500 grade material processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

Provide special product requirements to meet the personalized needs of customers. The NM500 grade material company arranges production and shipment strictly according to the contract, and guarantees to supply goods according to the time agreed in the contract. Provide professional consultation: we guarantee to answer any professional and NM500 grade material technical questions raised by users within 1 hour; provide detailed information.

NM500 grade material, NM series wear-resistant plates combine high hardness, high strength and high toughness, suitable for those severely worn occasions. The high wear resistance of the wear plate extends the service life of dump truck bodies, excavator buckets, crushers and similar equipment. The hardness of the wear-resistant steel plate is obtained through an effective quenching process. This method can not only achieve higher hardness, but also maintain a lower alloy composition in the steel. The produced wear-resistant plates are easy to machine, twist and weld.
