How to quickly judge whether the price of ASME SA709 carbon steel plate sheet, weathering steel plate is reasonable? What are the factors influencing the price quotation of ASME SA709 carbon steel plate sheet, weathering steel plate? First of all, the material composition of weathering steel plate is different, and the corresponding performance and price are also different. Therefore, when we talk about the price of ASME SA709 carbon steel plate sheet, weathering steel plate, we should first make clear of the material composition. Secondly, the specification especially the thickness of the ASME SA709 carbon steel plate sheet, weathering steel plate will affect the quotation. Generally, the thicker the weathering steel plate, the higher the price.

According to GB 11251 technical standard, the chemical composition of 40Cr structural steel plate is as follow: Carbon content is 0.37-0.44 %, Silicon content is 0.17-0.37%, Manganese content is 0.50-0.80%, Chrome content is 0.80-1.10%. 40Cr steel is usually in shape of 40Cr steel plates and bars. ASME SA709 carbon steel plate sheet, GB 11251 is for 40Cr structural steel plate with thickness range of 4-30mm. The tensile strength of 40Cr structural steel plate is 550-800Mpa. And its min. Elongation is 16%.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the ASME SA709 carbon steel plate sheet steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.

With a high-quality and complete after-sales service system, the company solves the user's hindrance and improves the reliability of steel ASME SA709 carbon steel plate sheet product quality. Reaching every corner of the globe with professional services, users anywhere can get thoughtful and detailed services form us is our pursue. We promise all our steel materials are manufactured and tested in accordance with responding standards. We will take full responsibility for the quality of the steel materials we provide.
