On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy RD 40 shipbuilding marine grade steel plate 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 RD 40 shipbuilding marine grade steel plate carbon alloy steel screws from China and India, according to the itc's affirmative ruling.

In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our RD 40 shipbuilding marine grade steel plate quality. Till now, we keep exporting around 100 tons per month as regularly.
Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the RD 40 shipbuilding marine grade steel plate steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
Ordinary carbon steel killed steel plate deoxidizes the liquid steel before making. When the liquid steel is poured into the ingot, its reaction is relatively calm and there is no boiling state. Advantages: this kind of steel plate RD 40 shipbuilding marine grade steel plate has no gas, less impurities, uniform stress and good welding performance. Widely used in demanding parts
