Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ~ 0.75, Mn: 0.20 ~ 0.50, P: 0.07 ~ 0.15, S≤0.03, Cu: 0.25 ~ 0.55 , Cr: 0.30 ~ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.

TMCP process is an indispensable technology for our production of low alloy high strength wide and thick steel plates. TMCP process can produce steel with high strength and toughness without adding too many alloy elements and complex subsequent heat treatment. TMCP is a process that can save alloy and energy and is beneficial to environmental protection. A lot of our shipbuilding steel plates are produced by TMCP process.

In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.A709 grade 50W carbon steel material
