Correct welding method for S355K2W railway vehicles steel

BBN STEEL is an agreement direct selling agent of Wuyang Iron and Steel Company, which mainly deals in medium and extra wide and extra thick steel plates. There are more than 8,000 tons of steel S355K2W railway vehicles steel plates of various specifications for customers to choose. The company's steel plate processing plant can cut semi-finished products and special-shaped parts according to user requirements, and can also transport on behalf of office roads, railways and shipping.

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced S355K2W railway vehicles steel production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, S355K2W railway vehicles steel steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

WTST 37-3 steel plate is a kind of carbon steel plate. WTST 37-3 steel plate can be used to build low temperature sea water resistant containers. When the customer orders S355K2W railway vehicles steel WTST 37-3 steel plate from us, our factory should roll it in full accordance with SEW 087-2 specification, and the factory will issue the original mill test certificate for inspection before delivery.

With the increase of temperature, the yield limit of S355K2W railway vehicles steel will decrease monotonically, but the tensile strength of S355K2W railway vehicles steel will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S355K2W railway vehicles steel. Near the blue brittleness temperature, the S355K2W railway vehicles steel strength increases and the plasticity decreases. The elongation and section shrinkage of S355K2W railway vehicles steel 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.
