A572 Gr 55 high strength steel,Our company was founded in 2000, which initially committed to providing high-quality steel products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export steel to the international market, opening up the international steel market.
A572 Gr 55 high strength steel,SA516Gr60 material, SA516Gr70, SA516Gr60N, SA516Gr70N steel plate in thickness ≤1.5in (40mm) is usually supplied in rolled state. The plate can also be ordered according to normalizing or stress relief, or normalizing plus stress relief. SA516Gr60 steel plate when thickness> 1.5in. (40mm) should be normalized. Unless otherwise specified by the customer, A572 Gr 55 high strength steel, SA516Gr60 steel plate (thickness ≤40mm) should be normalized when there is a notch toughness requirement.
A572 Gr 55 high strength steel,High-temperature boiler steel plates such as 15CrMoR plate, 12Cr1MoVR steel plate, ASME SA387 grade 22 steel, A387 Gr 91 boiler steel, ASME SA1017 Gr 23, SA1017 Gr 911, SA1017 Gr 122 steel, A572 Gr 55 high strength steel, must have features of:Sufficient high temperature durability and durable plasticity;Good high temperature tissue stability;Good high temperature oxidation resistance (heat resistance);Good hot and cold processing technology (mainly refers to cold bending deformation and weldability), etc,A572 Gr 55 high strength steel.
Rolling of steel plates is the core of the entire steel rolling production process. The billet is deformed by rolling. The rolling process plays a decisive role in product quality. The quality requirements of rolled products include the three aspects of product geometry and dimensional accuracy, internal organization and performance, and product finish. Finishing: It is the last process in the rolling process, and it is also a more complicated process. It plays a final role in guaranteeing the quality of the product.
Q345B steel plate strength has much to do with its thickness. First, the min. yield strength of Q345B steel plate: 345 Mpa for thickness ≤16mm, 335 Mpa for thickness 16-40mm, 325 Mpa for thickness 40-63mm, 315 Mpa for thickness 63-80mm, 305 Mpa for thickness 80-100mm, 285 Mpa for thickness 100-150mm, 275 Mpa for thickness 150-200mm, 265 Mpa for thickness 200-250mm. Second, the tensile strength of Q345B steel plate: 470-630 Mpa for thickness ≤100mm, 450-600 Mpa for thickness 100-250mm.
A572 Gr 55 high strength steel,After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
