The significance to develop 09cuptire-a corrosion steel

The company has a solid economic foundation, a strong network of relationships, complete technology and staffing. With my country’s entry into the WTO, the import and export trade is increasing day by day. In order to further meet the needs of 09CUPTIRE-A corrosion steel traders and importers and exporters, our company carefully builds for merchants One-stop service from door to door. We have a complete import and export service system in Mainland China, and 09CUPTIRE-A corrosion steel have established close cooperative relations with many shipping companies and airlines.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. 09CUPTIRE-A corrosion steel, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

Heat treatment specification and microstructure of 09CUPTIRE-A corrosion steel, 12Cr1MoV alloy plate:Heat treatment specification: quenching 970 ℃, air cooling; tempering 750 ℃, air cooling. Microstructure: bainite + ferrite.Mechanical properties of 12Cr1MoV alloy plate:Tensile strength σb (MPa)：≥490(50); Yield strength σs (MPa)：≥245(25); Elongation δ5 (％)：≥22; area shrinkage ψ (%): ≥ 50; Impact energy Akv (J): ≥ 71; Impact toughness value αkv (J/cm2)：≥88(9).

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the 09CUPTIRE-A corrosion steel principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
