20mm thick SA573 grade 70 carbon steel plate sheet price per ton

In today's SA573 grade 70 carbon steel plate sheet steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of SA573 grade 70 carbon steel plate sheet market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Chromium element (Cr element) can improve the strength and hardness of SA573 grade 70 carbon steel plate sheet, carbon steel in rolling state, reduce elongation and area reduction. When the chromium content is more than 15%, the strength and hardness will decrease, while the elongation and reduction of area will increase correspondingly. It is easy to obtain high surface processing quality for steel parts containing chromium after grinding. The main function of chromium element (Cr element) in quenched and tempered steel structure is to improve hardenability, so that the steel has better comprehensive mechanical properties after quenching and tempering.

A514Gr.Q material is a quenched and tempered high-strength weldable steel plate under the ASTM standard. It is mainly used in places where high tensile strength and high yield are required, engineering vehicle lifting gears, and racks for offshore platforms. Depending on the thickness, its hardness is between 235-290, the yield is greater than 630MPa, and the tensile strength is greater than 700MPa.

As of early November, China's pig iron output was 24.662 million tons. Although the output of pig iron has declined due to the suspension of production during the heating season, the rate of decline has been slow, still at a high level of over 24.5 million tons. This is 13.5% higher than the same period last year, which makes coke demand good, and the six rounds of increase have landed smoothly. Some areas such as Shandong even appear out of stock.
