Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). A709 grade HPS70W bridge steel plate, These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, A709 grade HPS70W bridge steel plate, offshore platform plate steel in stock.
After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, A709 grade HPS70W bridge steel plate tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of A709 grade HPS70W bridge steel plate steel and 542,000 tons of steel.
The addition of Ca element in steel such as A709 grade HPS70W bridge steel plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
The Metals Industry Organization last week discussed two things on the Article 232 of the U.S. Trade Expansion Act of 1962 “25% and 10% tariffs on imported A709 grade HPS70W bridge steel plate, steel and aluminum products, respectively”implemented in March 2018, and CBP - US Customs and Border Protection Administrative Office considered to delay the payment of import tariffs.
