China EN steel grade S355ML material mild carbon steel

A709 Gr50 plate is a structural steel for bridge, also known as high strength low alloy steel plate. EN steel grade S355ML material, A709 Gr50 steel is widely used in engineering structures, such as building steel structure, construction machinery, mining machinery, truck, bridge, pressure vessel, etc., especially for construction and engineering machinery parts requiring good weldability and toughness.

On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy EN steel grade S355ML material steel screw (Carbon and Alloy Steel Threaded Rod) to make a positive final anti-dumping and anti-subsidy industry damage. All five members of the international trade commission voted in favor of the ruling. The us department of commerce will issue anti-dumping and countervailing duty orders on imports of EN steel grade S355ML material carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of EN steel grade S355ML material, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
