In the first ten days of February 2020, the key statistics show that steel enterprises produce a total of 19.3943 million tons of crude steel, 17.9747 million tons of pig iron, 17.5904 million tons of steel and 3.225 million tons of coke. This ten day average daily output of A514 Gr B quenched and tempered steel crude steel is 1939400 tons, down 2.68% on a month on month basis, up 3.16% on a year-on-year basis; steel is 1759000 tons, down 9.09% on a month on month basis, up 2.51% on a year-on-year basis.
In line with the service concept of "honesty first, customer first" and the service tenet of "all for customer satisfaction", the company adopts the acceptance and response mode of combining manual and automatic, and accepts the diversified service demands of customer business consultation, complaint declaration, business acceptance, etc. through telephone, fax, e-mail, visit, letter, etc.
SA517GrQ material is a high-strength quenched and tempered alloy steel plate, which belongs to the steel for offshore oil drilling racks. The upper limit of SA517GrQ steel plate thickness is 150mm, and the upper limit of rack steel is 177.8mm. BBN STEEL has opened up a new heat treatment process route for the 177.8mm thick offshore platform rack steel A517GrQ, and strives to improve the production capacity of this product.
Chemical composition of Q420 steel: C ≤ 0.20, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.035, S ≤ 0.035, Nb ≤ 0.07, V ≤ 0.20, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.80, Cu ≤ 0.30, N ≤ 0.015, Mo ≤ 0.20. The mechanical properties of Q420 steel are: yield strength ≥ 340 MPa, tensile strength 500-680 MPa, elongation after fracture ≥ 18%, impact energy 34J. A514 Gr B quenched and tempered steel, Q420 steel has good mechanical properties and weldability, good cold and hot workability. Q420 steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts.
In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The A514 Gr B quenched and tempered steel products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.
