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 SA709 Grade 50W property 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 SA709 Grade 50W property plating can be customized according to your requirements.
Sulfur is a very harmful element in SA709 Grade 50W property steel. The presence of sulfur will increase the hot brittleness of steel, reduce the various mechanical properties of SA709 Grade 50W property steel, and reduce the weldability, impact toughness, fatigue resistance and corrosion resistance of steel.
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 SA709 Grade 50W property 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.
