ASTM A633 standard covers four grades A, C, D, and E normalized high-strength low-alloy structural steel plates for welded, riveted, or bolted construction. A573 Gr 70 steel sheet, A633 Grade A structural steel provides a minimum yield point of 42 ksi [290 MPa] in thicknesses through 4 in. [100 mm], inclusive. Grades C and D provide a minimum yield point of 50 ksi [345 MPa] in thicknesses up to 2.50 in. [65 mm], inclusive and 46.0 ksi [315 MPa] in thicknesses over 2.50 in. to 4.0 in. [65 to 100 mm], inclusive.
In order to further promote the ultra-low emission process and the technological innovation of flue gas treatment technology in China's steel industry, the China Institute of Metals and Beijing China-Japan Energy Conservation and Environmental Protection Engineering Technology Co., Ltd. (hereinafter referred to as Beijing China-Japan Alliance) will carry out technical cooperation to promote the activated coke dry process The application of desulfurization and denitrification technology in iron and steel enterprises, the signing ceremony of technical cooperation between the two parties was successfully held recently at the Chinese Institute of Metals.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. A573 Gr 70 steel sheet, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
