Improvement measures for the surface pit defect of 09cupcrni-a steel material

The company has a perfect after-sales service system and quality assurance system. The company adheres to the service principle of "all for users", and has established a professional after-sales service team. In the future service process, the after-sales service adopts regular return visit for customers. Timely understand the customer's satisfaction with our products, and solve the user's problems at any time.

Q690E material has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance. In addition, 09cupcrni-a steel material, Q690 high strength steel plate and sheet has good corrosion resistance and certain wear resistance. High strength, especially in the normalizing or normalizing plus tempering state has a higher comprehensive mechanical properties.

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The 09cupcrni-a steel material, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.

S700MC high-strength cold-formed hot-rolled steel sheet 09cupcrni-a steel material more greatly improves the yield strength than traditional steel grades, and at the same time has good elongation performance, cold bending performance, welding performance and impact resistance. S700MC high-strength steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, lifting machinery, mining machinery and other large-scale welding structural parts.

Over the years, the company has strived for perfection, being well-received. By virtue of stable product performance, high-quality engineering effects and perfect service system, we have won the trust of many customers, and our engineering cases and after-sales service systems are spread all over the world. We regularly conduct quality tracking and return visits by phone and email, listen to customers' opinions, and continuously improve service quality.
