Supply the NM400 steel for vehicle sheet/coil mechaical properties

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of NM400 steel for vehicle welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.

The three factors of wear of NM450 wear plate, NM400 steel for vehicle are as follows:(1) The relative motion between two objects, no relative motion, no wear.(2) Surface properties of materials.(3) Contact characteristics with another object (including contact mode, force transmission mode, surface deformation, interaction, etc.).

The company always insists on quality first. "Tolerance and trust, change and innovation, abide by rules, and focus on refining people" are the eternal credo of the team. Encouraged by the same creed and belief, BEBON people continue to grow and mature, and the team size is increasing expand. In the future, look beyond Chinese private steel companies to see BEBON. Looking to the future, we are not blindly pursuing bigger scale, but we are pursuing strength and brand strength.

The qualified flat steel has sufficiently high high temperature strength and high temperature plasticity. Therefore, NM400 steel for vehicle flat steel is not only required to have high enough normal temperature and instantaneous high temperature tensile strength and plasticity, but also long-term strength and long-term plasticity to ensure long-term safe work at high temperatures, especially under creep leakage conditions. The product thickness is 8-50mm, width 150-625mm, length 5-15m。
