weldability of nm400 plate material standard

The factory is located in the central China, with convenient transportation and abundant resources. The main products are various construction steel plates, steel pipes, steel sections, and steel structure processing parts. Used in the weldability of NM400 plate manufacture of railway tracks, pressure vessels, boilers, hulls, bridges, various types of steel, etc. With an annual output of 2.23 million tons of steel plates, 2.04 million tons of steel pipes and 1.54 million tons of section steel in 2002, it is an important pig iron base in Henan Province.

API 5L X70 steel plate/pipes, API 5L X70 steel plate/pipes, under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

Hot rolled weldability of NM400 plate 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 weldability of NM400 plate 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.

our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than weldability of NM400 plate 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

The company specializes in heavy plate cutting, carbon steel pplate processing, carbon plate welding processing and sales of wide and thick steel weldability of NM400 plate plates. It has high-quality CNC steel plate cutting and processing equipment, a professional technical personnel team, and supporting logistics distribution and after-sales service system. BBN company provides customers with solutions at low prices, high quality, and fast response service.
