Analysis of fault layer problem of 09CuPCrNi-A chemistry

The company has strict control on the quality of 09CuPCrNi-A chemistry. Each 09CuPCrNi-A chemistry is inspected for the whole process, including raw material purchase, production process according to the procedures and relevant regulations. According to the technical standards and technical requirements, the composite quality inspection is carried out to confirm whether the 09CuPCrNi-A chemistry meets the specified quality requirements. If the 09CuPCrNi-A chemistry does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified 09CuPCrNi-A chemistry shall be removed, marked, registered and effectively isolated; the 09CuPCrNi-A chemistry shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating 09CuPCrNi-A chemistry production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

S355NC steel offers excellent bending, flanging, cold-bordering and folding 09CuPCrNi-A chemistry properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

Weather-resistant steel is atmospheric corrosion-resistant steel. It is a low-alloy steel that has better corrosion resistance in the atmosphere than ordinary carbon steel by adding a small amount of alloy elements. Compared with 09CuPCrNi-A chemistry, weathering steel Q355NH, Q355GNHE weathering steel has better resistance to atmospheric corrosion. It is necessary to ensure that the steel plate has high strength and good plasticity and toughness. In addition, by adding a corrosion-resistant element to ensure the atmospheric corrosion resistance index I to reflect its good corrosion resistance.

After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
