Automobile steel sheet is mainly used to manufacture automobile girders (longitudinal and cross girders), frame and other structural parts. The automobile girder should not only bear heavy static load, but also bear certain impact, vibration, etc., so the steel sheet A514 Gr B alloy steel plate is required to have certain strength and fatigue resistance, as well as better stamping performance and cold bending performance to meet the requirements of cold stamping processing.
A514 Gr B alloy steel plate, 30CrMnSiA steel has good machinability, small processing deformation and good fatigue resistance. If 30CrMnSiA steel is used to make a tool, it is processed to the tool shape by rough machining. Mill the cutting edge with a cemented carbide milling cutter and polish it with a polishing machine. There should be no problem for the surface roughness reaching 3.2. 30CrMnSiA steel has high strength, sufficient toughness and good hardenability after quenching and tempering. After quenching and tempering, 30CrMnSiA steel can be used for grinding wheel shafts, gears and sprockets.
Primary processing, steel plate cutting processing cutting method, it is a flame cutting, because it to the accuracy requirement of the cutting size is not very high, the thickness of the A514 Gr B alloy steel plate plates in a certain range can be a good cutting quality and cutting effect, and the cut surface can be very smooth, however, it is important to note that in this work, is the need to pay attention to steel plate deformation at high temperature.
The company has a high-quality management, technology and R&D team, and adopts independent research and development, domestic innovative process optimization combination. Relying on advanced manufacturing technology and sophisticated production testing equipment, it has ensured the high quality of products A514 Gr B alloy steel plate and won a good reputation. We can offer various kinds of steel materials in GB, ASME, ASTM, JIS, DIN, EN, API standards and specifications.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
