On March 19, 2020 the us international trade commission (ITC) vote on imports from China and India's carbon alloy A709 Gr 50 bridge 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 A709 Gr 50 bridge steel plate carbon alloy steel screws from China and India, according to the itc's affirmative ruling.
Smelting process of A709 Gr 50 bridge steel plate, container plate SPA-H weather-resistant steel: The molten iron for smelting SPA-H steel must be pretreated by molten iron desulfurization. Before entering the converter, the sulfur content of the molten iron is ≤0.010%, and the slag on the surface of the molten iron is cleaned. Nickel plates, copper particles or nickel-copper alloys are added to the converter with scrap steel. The carbon content of the converter smelting end is required to be less than 0.06% to prevent the molten steel from being oxidized.
Steel transportation because of the special material of A709 Gr 50 bridge steel plate steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
At present, the overall market demand of A709 Gr 50 bridge steel plate is weak, the purchase intention of end users is not strong, and the purchase is basically on demand. The market transaction of A709 Gr 50 bridge steel plate is relatively general, and some markets have declined. However, the overall market inventory of A709 Gr 50 bridge steel plate is not high, coupled with the strong willingness of steel mills to support price, and the high resource cost in the later stage, therefore, businesses are not willing to sell of A709 Gr 50 bridge steel plate at too low price. On the whole, the short-term market of A709 Gr 50 bridge steel plate is expected to be dominated by high fluctuations.
The high strength A709 Gr 50 bridge steel plate low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of A709 Gr 50 bridge steel plate ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
The company always insists on quality first. "Tolerance and trust, change and innovation, abide by rules, and focus on refining people" are the eternal credo of the team. Encouraged by the same creed and belief, BEBON people continue to grow and mature, and the team size is increasing expand. In the future, look beyond Chinese private steel companies to see BEBON.
