The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our A131 grade D ship repairing steel steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge A131 grade D ship repairing steel steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.
Types of steel plates our company supply: A36 carbon structural steel plate, A572 low-alloy high-strength steel plate, A131 grade D ship repairing steel, steel plate for bridge, S355 steel plate for building structure, Grade AH36 steel plate for shipbuilding and offshore platform, steel plate for boiler and pressure vessel, mould steel plate, steel plate for alloy structure, API 5L Gr.B pipeline steel plate, high-strength high toughness steel plate, corrosion-resistant steel plate, composite steel plate, wear-resistant steel plate.
The wear-resistant layer of A131 grade D ship repairing steel wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy A131 grade D ship repairing steel carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
A131 grade D ship repairing steel, Q345B steel is high strength low alloy HSLA steel. Due to the addition of alloy elements, the yield strength of Q345B and so on HSLA steel is 25% - 150% higher than that of carbon structural steel with the same carbon content. Using HSLA structural steel instead of carbon structural steel can reduce the self weight of the structure, save metal materials and extend the service life of the structure.
A131 grade D ship repairing steel, 09CuPCrNi-A weather resistant steel is origined in China. Its equivalent grades are JIS SPA-H, BS WR50A, Corten steel, etc. The Cu, P, Cr, Ni are important elements that gave 09CuPCrNi-A weather resistant steel its weathering ability. The Cu content of 09CuPCrNi-A steel is 0.25–0.50, P content is 0.060-0.12, Cr content is 0.30-1.25, Ni content is 0.12-0.65. For 09CuPCrNi-A steel coil ≤ 4mm, the min. yield strength is 310Mpa, min. tensile strength 440Mpa. For 09CuPCrNi-A steel sheets >4mm, the min. yield strength is 345Mpa, min. tensile strength 480Mpa.
The company's products A131 grade D ship repairing steel have excellent quality, reasonable prices and strong usability, and are well received by users. Survive by quality, expand the market with integrity, continuously research and develop new products, expand varieties, to meet market demand, and make the company continue to grow. The needs and interests of users are our high philosophy of service and commitment, and customer satisfaction is our eternal pursuit.
The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
