usage of NM400 steel plate sheet with high tensile properties

Delivery status: Hot-rolled usage of NM400 steel plate steel In the hot-rolled state or controlled rolling state or heat treatment, the state of delivery, cold-rolled steel to the annealing state of delivery.

The wear-resistant layer of usage of NM400 steel plate wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy usage of NM400 steel plate carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.

The preparation of usage of NM400 steel plate galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for usage of NM400 steel plate centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide usage of NM400 steel plate cutting, bending and so on processing to change plate size and shape according to your requirements. Welcome to consult us about usage of NM400 steel plate ASTM A204 grade B properties, SA 516 gr 70 temperature range, ASTM A285 grade C chemical composition, boiler steel price and so on questions and ask for offer.

Our company has established and constantly improved the customer service system and emergency response system. Through the customer service management system, we track the service of the after-sales service team and provide efficient and standard services in time. At the same time, the company formulates a regular return visit system, compares the historical cases of customer problems, proposes a pre solution, and ensures that the service is in place in a short time.
