The company adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the A514 Gr B QT steel plate production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.
45Mn carbon structural steel can obtain better comprehensive mechanical properties after quenching and tempering. The cutting performance is still good, but the welding performance is poor, the cold deformation plasticity is low, and there is a tendency to temper brittleness. It is generally used in the quenched and tempered state, and A514 Gr B QT steel plate can also be used in Used in quenched and tempered or normalized state.
Flat steel is a kind of steel with rectangular cross-section and blunt edges at the edges and corners. It is usually 12-300 mm wide and 3-60 mm thick. Compared with A514 Gr B QT steel plate ordinary steel plate, the utilization rate of flat steel is increased by one to five percentage points. Moreover, flat steel can be produced with fixed thickness, width and length according to the user's requirements, which saves the cutting process for users, reduces the consumption of labor and materials, and also reduces the processing loss of raw materials, saving time, labor and material.
Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest A514 Gr B QT steel plate processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain A514 Gr B QT steel plate by rolling method.
A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. A514 Gr B QT steel plate, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.
Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our A514 Gr B QT steel plate service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's A514 Gr B QT steel plate customer service to establish a good, comprehensive, full service system.
