Our company specializes in the production of steel plates, steel coil, steel sections, welded pipes and seamless pipes products, sales of GB, ASME, ASTM, JIS, DIN, EN, API and other standards and specifications of steel A709 grade 50S bridge steel plate and deep-processed products, facing the domestic and foreign markets, welcome to call for inquiries. It is a modern high-tech professional enterprise integrating scientific research, production and sales.
Our company can produce A709 grade 50S bridge steel plate, EN10025-2 S355J2 structural steel plates and sheets up to 400mm thickness. S355J2 steel consists of S ( for structural steel), 355 (indicates the minimum specified yield strength value in MPa for thickness less than 16mm), J2( for a minimum impact energy value of 27J at -20ºC). EN S355J2 structural steel plates are suitable for cold flanging, delivery condition normalized rolled or as rolled.
Our stainless steel mainly is stainless steel plate/Coil. We keep 2600 tons stainless steel plate and coil A709 grade 50S bridge steel plate in stock. And we refresh the our new stock every month. All the stock products from reputable mills like like TISCO, ZPSS, IISCO, LISCO, Bao steel and so on. We put all our products in Shanghai and Tianjin warehouse, which is near the loading port.
With the increase of temperature, the yield limit of A709 grade 50S bridge steel plate will decrease monotonically, but the tensile strength of A709 grade 50S bridge steel plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of A709 grade 50S bridge steel plate. Near the blue brittleness temperature, the A709 grade 50S bridge steel plate strength increases and the plasticity decreases. The elongation and section shrinkage of A709 grade 50S bridge steel plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
The carbon content of A709 grade 50S bridge steel plate, medium carbon steel plate is 0.25% - 0.60%. In addition to carbon, it can also contain a small amount of manganese (0.70% - 1.20%). The medium carbon steel plate after quenching and tempering has good comprehensive mechanical properties. The highest hardness is about HRC55 (hb538) and σ B is 600-1100mpa.
We are professional A709 grade 50S bridge steel plate carbon steel plates supplier with good reputation, and have participated many significant projects that finished with carbon steel materials in the world. If you have any question about carbon steel materials, such as A36 steel modulus of elasticity, A283 grade C properties, A572 grade 50 hardness, A709 grade 50S bridge steel plate EN 10025 S235JR equivalent Indian standard, S355JR specification, carbon steel price etc., please feel free to consult us.
