High strength SMA490AP hot-rolled atmospheric corrosion resisting steel with 2550mm width

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

Q345qCNH grade is a weather-resistant structural steel for bridges. Bridge steel grade is Q345qC. It is produced by the standard GB / T714-2014. Weather-resistant bridge plate Q345qCNH is a kind of structural steel plate for bridge. Add a certain amount of alloy elements, such as P, Cr, Ni, Cu, Mo, etc. to the steel to form a protective layer on the surface of the metal substrate to improve the atmospheric resistance corrosive steel.

As for the mechanical properties of SMA490AP hot-rolled atmospheric corrosion resisting steel, ASTM A572 Gr.50, 345 Mpa is the yield point levels most closely approximating a geometric progression pattern between 36 ksi min yield point steels covered by Specification A36/A36M and 100ksi min yield point steels covered by Specification A514/A514M.

Steel production and rolling technology and equipment also pursue the continuity between processes, such as the continuous SMA490AP hot-rolled atmospheric corrosion resisting steel process between continuous casting and rolling mills, continuous casting slabs hot transfer hot charging, increased direct rolling, and continuous cold rolling processes. The development of controlled rolling and controlled cooling technology that combines rolling and heat treatment has played a huge role in improving the properties of rolled materials.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.
