The company specializes in producing high-strength low-temperature resistant low alloy plates Q345C, Q345D, Q345E, SM400, A514 grade Q quenched and tempered steel, SM490, S355J2 + N;bridge plates Q345qC / qD / qE, Q370qE high-strength structural plates, etc. Z-direction performance (Z15, Z25, Z35). Above materials have high yield strength, high tensile strength, Brinell hardness, and Rockwell hardness; and low temperature resistance, they also can be maintained at high temperatures of -60 ℃.
Over the years, the company has established a standard of A514 grade Q quenched and tempered steel steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to A514 grade Q quenched and tempered steel quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
The related factors of A514 grade Q quenched and tempered steel steel plate cutting are mainly steel plate material, steel plate specific use and steel plate cutting requirements, so it can be said that there are many related factors. Different processing methods, such as finish machining and rough machining, choose different A514 grade Q quenched and tempered steel steel plate cutting methods. Wire cutting or plasma cutting is used for finishing and flame cutting is used for rough machining. Therefore, it can be concluded that the steel plate cutting methods selected under different processing methods are different.
A514 grade Q quenched and tempered steel, Q345B low alloy steel plate composition: 1) Low carbon: Due to the high requirements for toughness, weldability and cold forming properties, its carbon content does not exceed 0.20%; 2) Add manganese-based alloying elements; 3) Adding auxiliary elements such as niobium, titanium or vanadium: a small amount of niobium, titanium or vanadium forms fine carbides or carbonitrides in the Q345B steel, which is conducive to obtaining fine ferrite grains and improving the strength and toughness of the steel; In addition, adding a small amount of copper (≤0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. Adding a small amount of rare earth elements can desulfurize and degas, purify steel, improve toughness and process performance.
After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication. After sales service personnel must do what they say in the process of communication with customers.
