In recent years, in line with the development trend of iron and ASTM A709 bridge steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which ASTM A709 bridge steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Wear resistant steel plate ASTM A709 bridge steel plate is an important material for industrial application. The traditional wear resistant steel is the high manganese steel which hardens under the impact load. The premise of its function must be subjected to enough impact load. With the development of wear resistant steel technology, NM series steel plate breaks through the limitation of traditional high manganese steel and realizes the application space of wear-resistant steel. The main ASTM A709 bridge steel plate grades of NM series wear resistant steel plates are NM360, NM400, NM450, NM500, NM550, NM600.
Weathering steel plate ASTM A709 bridge steel plate for welding structure is made by adding chromium, molybdenum, titanium, vanadium and other metal materials into common steel liquid. Adding these materials can form a protective film on the surface, which can resist the corrosion of climate for a long time. Advantages: this kind of steel plate ASTM A709 bridge steel plate has excellent welding performance and weather resistance, and is widely used in railway, bridge and other areas requiring long-term exposure to the atmosphere.
The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the ASTM A709 bridge steel plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
SS400 is a low carbon steel with no specified carbon content. According to its mechanical properties, it is similar to ASTM A709 bridge steel plate ASTM A36, which is widely used in engineering and industrial applications. The cost of JIS SS400 steel angle steel structure is low, and it has good performance in major projects. SS400 angle steel description:Item: SS400 angle steel. ASTM A709 bridge steel plate Standard: JIS G3101-2004. Technology: hot rolled. Type: equal & unequal. Surface: black or galvanized. Length: 6 m, 9 m, 12 m or per your request. Equal angle: Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 to 20 mm. Length: 6 m, 9 m, 12 m or per your request. Unequal angle: Size: 30 × 20 mm to 250 × 90 mm.
