At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick NM450 wear-resistant steel steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.
Participating tenders with clients is part of our NM450 wear-resistant steel business. Every year, we support a lot of clients to win tenders and supply steel materials to their govenment progects or state owned enterprise. Until now, we have built NM450 wear-resistant steel long-term cooperation for many govermental departments of different countries such as Peru, Bangladesh, Indonesia, Egypt, Qatar, etc.. And we have built certain influence and credibility on the International market.
Large-thickness NM450 wear-resistant steel, Z35 grade steel plate is a kind of extra-thick steel plate that is applied under specific environmental conditions, such as the key parts such as the turbine seat ring and guide vane of the generator set. It has high requirements for safety, reliability, and long service life. Develop 200mm-300mm thick steel plate of Z35 level, to ensure that the layer tear resistance reaches Z35 level. 300mm thick Z35 grade steel plate can be used not only in the hydropower industry, but also in the manufacture of other large key equipment, and has broad prospects.
Hardfacing wear-resistant steel plate is a kind of wear-resistant steel plate with double-layer structure. In order to make it into wear-resistant parts better, it is necessary to weld and assemble the wear-resistant steel plate, NM450 wear-resistant steel. In order to ensure the original comprehensive performance of hardfacing steel plate, the base layer, transition layer and clad layer should be welded respectively. During the welding of hardfacing wear-resistant steel plate, the welding shall be carried out in strict accordance with the drawing, welding process and relevant standards.
