In recent years, in line with the development trend of iron and ASTM A573 welding structural steel 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 A573 welding structural steel 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.
Low alloy coils are steel coils made of steel with a low alloy content, usually less than 3.5%. Low alloy coil materials mainly include A572 Gr 50, S355JR, SS490, ST52-3, Q345B, etc.. These grades are also the most widely used and produced low-alloy high-strength steel grades in the world. The strength of low alloy coils is about 20% to 30% higher than that of ordinary carbon structural steel, ASTM A573 welding structural steel. And the atmospheric corrosion resistance of low alloy coils is 20% to 38% higher than that of ordinary carbon structural steel.
We have a lot of advantages for ASTM A573 welding structural steel steel plate processing. First, we have huge steel plate stock. That not only saves material preparation time, but also saves much transportation cost. Second, we have professional technical team, who can design drawing according to client requirements quickly. Or if clients have drawing, we can communicate and make it clear soon. Third, we have built special steel processing center. The professional and experienced work will make you more satisfied and at ease.
Temperature has a great influence on the strength of the material, ASTM A573 welding structural steel. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
ASTM A573 welding structural steel, St52-3 steel is a low alloy, high strength structural steel which can be readily welded to other weldable steel. St52-3 steel’s mechanical properties is yield strength more than 355 MPa, tensile strength 490-630Mpa. For St52-3 steel, the C element content is 0.24%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.045% max, the S element content is 0.045% max.
