The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the weathering steel SMA490AP, alloy steel is very high, it is not easy to break and can be used for a long time.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the weathering steel SMA490AP quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After weathering steel SMA490AP quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate weathering steel SMA490AP for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 weathering steel SMA490AP and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
