hardness of SMA490CW corten steel sheet material analysis

Strengthen system construction. The system itself has a certain binding force, which specifies the rights and obligations of employees. It is a passive management means for employees. Its purpose is to promote each employee to develop good professional habits, form good behavior norms, and promote the improvement of enterprise management level.

EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll hardness of SMA490CW corten steel sheet, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.

Alloy steel plate is a kind of high strength steel plate, which has good wear resistance. It is suitable for road laying, factory floor and other fields with high wear resistance requirements. The performance of the hardness of SMA490CW corten steel sheet, alloy steel plate is more prominent. The alloy steel plate has good high temperature resistance and low temperature resistance, which will not cause material deformation in any high temperature and low temperature environment. The strength retention of alloy steel plate is better, and the material stability is better.

Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.
