Our company was founded in 2000, which initially committed to providing high-quality steel GL-D40 ore carrier steel plate products for China's rapid infrastructure construction. With the advantages of steel resources and good reputation in the domestic market, combined with the huge demand for steel in the international market, we began to export GL-D40 ore carrier steel plate steel to the international market, opening up the international steel market.
The theoretical weight of seamless steel pipe is the weight per meter of steel pipe calculated by the calculation formula: meter weight = (outer diameter - wall thickness) * wall thickness * 0.02466, in which the outer diameter refers to the farthest distance between the outer walls on both sides of the steel pipe, and the wall thickness is the thickness of the seamless steel pipe wall. The weight per meter of GL-D40 ore carrier steel plate seamless steel pipe is calculated by the formula. If you want to get the weight of the whole seamless steel pipe, you should multiply the actual length of the steel pipe.
Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The GL-D40 ore carrier steel plate metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other GL-D40 ore carrier steel plate alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary GL-D40 ore carrier steel plate carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.
The correct choice of billet type, section shape, size and weight are of great significance to GL-D40 ore carrier steel plate steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The GL-D40 ore carrier steel plate rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The GL-D40 ore carrier steel plate, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.
