Based on the advantages of A572 grade 50 high strength steel 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 grade 50 high strength steel 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 .
SA387 Gr.12 Cl.2 steel data is suitable for the essence and gas treatment in hydrogenation reaction and conversion equipment at high temperature. It is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers. The maximum thickness of the steel plate can reach 250mm. According to different A572 grade 50 high strength steel thickness and impact requirements, the delivery situation of SA387 Gr.12cl.2 steel plate is: normalizing and tempering or normalizing and rapid cooling and tempering.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A572 grade 50 high strength steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
A572 grade 50 high strength steel Weldability refers to the performance of the weld joint with the expected quality requirements obtained by common welding methods under specific structure and process conditions. Weldability is generally judged by the crack sensitivity and the change of mechanical properties of weld zone. The ability of steel materials to withstand bending without cracking at room temperature is called cold bending. The greater the bending capacity before crack, the better the cold bending performance of the steel material.
A572 grade 50 high strength 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.
