What is SMA400AW cold rolled weathering steel strip equivalent material in China

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of SMA400AW cold rolled weathering steel strip circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and SMA400AW cold rolled weathering steel strip management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

The SMA400AW cold rolled weathering steel strip atmospheric corrosion resistance of high weather resistant structural steel is better than that of welding structural weathering steel, and is mainly used for bolt connection, riveting and welding structural parts for vehicles, containers, buildings, towers and other structures. But the welding performance of welding structural weathering steel is better than that of high weather resistant structural steel, and the welding structural weathering steel is mainly used for welding structural parts for bridges, buildings and other structures.

The weldability of SMA400AW cold rolled weathering steel strip is good. It means that under certain process and construction conditions, SMA400AW cold rolled weathering steel strip can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.

The characteristic of niobium in SMA400AW cold rolled weathering steel strip etc. steel material is to increase the recrystallization temperature of austenite, so as to achieve the purpose of refining austenite grains. In general, the amount of niobium added in steel material is less than 0.05%, and the contribution of niobium above 0.05% to strengthening and toughening will no longer be obvious.

SMA400AW cold rolled weathering steel strip, No. 20 steel belongs to high-quality carbon steel.No. 20 steel means steel with an average carbon content of 0.20%;The thermal conductivity of No. 20 steel at 315℃ is 48 W/m℃;No. 20 steel is generally not quenched, the general treatment method is carburizing or normalizing;The yield strength of No. 20 steel is not less than 250MPa;The tensile strength of No. 20 steel is not less than 420MPa;Elongation of No. 20 steel is not less than 25%;The reduction of area is not less than 55%;The density of SMA400AW cold rolled weathering steel strip and No. 20 steel is 7.85kg/cm3
