The ASTM A36 I beam has moderate tensile and yield strength because of its low carbon content and no other alloying elements. A36 steel beam A573 Gr.70 steel TStE420 steel comparison is commonly used in construction and civil engineering because of its competitive low cost and good welding, forming and processing properties. The hot-dip galvanized carbon steel beam can effectively protect the steel from the corrosion of weather and environment. The amount of zinc A573 Gr.70 steel TStE420 steel comparison plating can be customized according to your requirements.
Since March 20, 2020, the export tax rebate rate of some steel products in China has been increased. According to statistics, the export volume of A573 Gr.70 steel TStE420 steel comparison and so on steel products within the adjustment scope in 2019 is 18.888 million tons, accounting for 29.4% of China's total steel exports; the export volume is 14.05 billion US dollars, accounting for 26.1% of the total steel exports. The adjustment will be conducive to the export of some steel products in China and reduce the purchase cost of foreign customers.

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This A573 Gr.70 steel TStE420 steel comparison rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.
