Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;

SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa. This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, and excavators used in mines and various engineering constructions.

A335 P22 steel pipe belongs to ferrite alloy steel nominal pipe for high temperature use. Chemical composition of A335 P22 steel pipe: C 0.10-0.20, Mn 0.30-0.80, P ≤ 0.025, S ≤ 0.025, Si 0.10-0.50, Mo 0.44-0.65. Mechanical properties of A335 P22 steel pipe: tensile strength 415mpa, yield strength 205 MPa. EN S275M steel plate, A335 P22 steel pipe is characterized by good process performance, less sensitivity to the heating temperature of heat treatment, good welding performance, good plasticity, and low strength, especially the high temperature rupture strength is lower than 12Cr1MoV steel. When used at the same temperature and stress, its wall thickness is about 30% thicker than 12Cr1MoV Steel.

Corrosion resistant steel is a kind of steel which can resist corrosion in air or weak medium and other strong corrosive medium. Corrosion resistant steel is also a kind of stainless steel. The corrosion resistance of corrosion resistant steel is better than that of stainless steel. EN S275M steel plate, Corrosion resistant steel has good machinability and high corrosion resistance in normal indoor environment. In the project, it can be used for its good corrosion resistance, and can be cut into steel with desired shape at will.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.

We are committed to providing customers with high-quality services, high-precision products and efficient solutions. If you have any demand for EN S275M steel plate steel plate, steel pipe and other products, please contact us directly. We are willing to provide you with relevant product knowledge and specific specifications for free. Welcome to purchase.
