Based on the advantages of A572 Gr 55 CS steel carbon plate steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel A572 Gr 55 CS steel carbon plate products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
A572 Gr 55 CS steel carbon plate, Q345 angle steel has two kinds: unequal angle steel (two sides are not the same size) and equal angle steel (two sides are the same size). A572 Gr 55 CS steel carbon plate, Q345 angle steel is widely used for mechanical processing, building structure, steel structure, etc.. In addition, Q345 angle steel can withstand - 40℃ low temperature at least and can be used in cold areas. The weight calculation formula of Q345 angle steel: 0.00785 * (side width + side width - side thickness) * side thickness, the value obtained is the weight per meter, and then multiplied by the length to calculate the weight of a piece.
A572 Gr 55 CS steel carbon plate, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.
The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of A572 Gr 55 CS steel carbon plate, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, A572 Gr 55 CS steel carbon plate.
The gas cylinder steel is one of our featured products. The pickled LPG steel is available. We supply gas cylinder steel coil, gas cylinder steel sheet and gas cylinder A572 Gr 55 CS steel carbon plate steel plates. Welcome to consult any question about gas cylinder steel or LPG steel, such as JIS G3116 SG295 coil price, SG255 material properties, SG325 plate dimensions, HP265 equivalent, P245NB steel properties, etc. We are always here to serve you.
The company strengthens process management and pays attention to assessment. One of the key points of good service is to strengthen the process management and improve the evaluation mechanism. Make the after-sales service system more perfect and provide better service for customers.
