How to improve the quality of 09CuPTiRE-A high weather and corrosion resistant steel

The whole plant covers an area of 18,480 square meters, a workshop area of 9,500 square meters, and a final assembly workshop of 4,300 square meters; fixed assets are 25.50 million yuan. The company has 09CuPTiRE-A high weather and corrosion resistant steel strong technical force, complete quality assurance system sophisticated tooling equipment and advanced technology. It can provide high efficiency professional equipment and 09CuPTiRE-A high weather and corrosion resistant steel pressure vessels for domestic and foreign chemical, petroleum, chemical, metallurgical, pharmaceutical, fertilizer, textile, and environmental protection industries.

The company has strict control on the quality of 09CuPTiRE-A high weather and corrosion resistant steel. Each 09CuPTiRE-A high weather and corrosion resistant steel 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 09CuPTiRE-A high weather and corrosion resistant steel meets the specified quality requirements. If the 09CuPTiRE-A high weather and corrosion resistant steel does not meet the quality requirements, the non conformity control shall be implemented, and the unqualified 09CuPTiRE-A high weather and corrosion resistant steel shall be removed, marked, registered and effectively isolated; the 09CuPTiRE-A high weather and corrosion resistant steel shall be inspected and confirmed for acceptance, release and delivery, and the quality certificate shall be issued.

Our SA516Gr70 pressure vessel plate has good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-layered cracking performance, micro-alloying, high purity, low carbon equivalent, strong resistance to sulfur and hydrogen. The product has good dimensional tolerance and surface quality. China made 09CuPTiRE-A high weather and corrosion resistant steel steel plates are now widely used in major chemical sites.

The purpose of alloying Q345B steel is to use the interaction of alloy elements with iron and carbon and the effect on iron-carbon phase diagram and the heat treatment of steel to improve the structure and properties of steel. Interaction of alloying elements with iron and carbon: After alloying elements are added to steel, they mainly exist in steel in three forms. That is: forming a solid solution with iron; forming carbides with carbon; and possibly forming intermetallic compounds in high alloy steels, 09CuPTiRE-A high weather and corrosion resistant steel.

Chemical composition differences between the 09CuPTiRE-A high weather and corrosion resistant steel, Q345 steel grades (Q345A / Q345B / Q345C / Q345D / Q345E):Q345A steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345B steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.035，S≤0.035； Q345C steel：C≤0.20，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.030，Al≥0.015； Q345D steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.030，S≤0.025，Al≥0.015； Q345E steel：C≤0.18，Mn ≤1.70，Si≤0.50，P≤0.025，S≤0.020，Al≥0.015； All the Q345 steel grades contain Nb≤0.07，V≤0.15，Ti≤0.20，Cr≤0.30，Ni≤0.012，Mo≤0.10。

The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products 09CuPTiRE-A high weather and corrosion resistant steel more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users". As a leading international steel supplier, BEBON have two warehouses which are near by Tianjin port and Shanghai port.

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.
