Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, A514 Gr B QT steel plate quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the A514 Gr B QT steel plate International leading steel materials supplier.
A514 Gr B QT steel plate, High-strength steel plates are widely used in many industries such as construction, automobiles, ships, machinery and equipment, but high-strength steel plates must be selected appropriately. First, the grade is too high, which means that the price will be high because of the high manufacturing cost. Second, the low level means that the safety performance cannot meet the standard. Third, we must strictly follow the design drawings to select high-strength steel plates specifications. Fourth, it is advised the purchaser to test the high-strength steel plates with special equipment.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the A514 Gr B QT steel plate alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the A514 Gr B QT steel plate wear-resistant property to meet the requirements of specific working conditions.
Different from A514 Gr B QT steel plate, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
15Mo3 steel plate is used for boiler and high temperature pressure vessel.15Mo3 steel plate executive standard: DIN17155Delivery status of A514 Gr B QT steel plate, 15Mo3 steel plate: normalizingNormalizing temperature of 15Mo3 steel plate: 650 ~ 700 ℃Normalizing time of 15Mo3 steel plate: 1.5t-2.5t15Mo3 welding repair: welding repair can only be carried out after the approval of the purchaser.Requirements for tensile properties of 15Mo3 steel plate: tensile strength 450-600 MPa, yield strength 270 MPa.
