HSLA structural 09cuptire-a steel grade yield strength

The company's operation is based on the principle of "quality for survival, reputation for development". In terms of management, we adhere to the principle of people-oriented, service-oriented and customer-oriented. All staff of the company have the courage to open up, unite and forge ahead, and work hard to grasp the good situation of global economic development, actively strengthen communication with outstanding enterprises in the 09CUPTIRE-A steel grade industry, keep pace with the times, and move towards a new course!

The working pressure of high pressure boiler steel tube is generally above 9.8 MPa, and the working temperature is between 450℃ and 650℃. The materials of high pressure boiler steel tubes are: 20G, 20MnG, 25MnG, 15CrMoG, 12Cr2MoG, 12Cr1MoVG, 12Cr2MoWVTiB, 10Cr9Mo1VNb, SA210A1, SA210C, SA213 T11, SA213 T12, SA213 T22, SA213 T23, SA213 T91, SA213 T92, ST45.8, 15Mo3, 13CrMo44, 10CrMo9-10, 09CUPTIRE-A steel grade and so on.

When using 09CUPTIRE-A steel grade, low-alloy high-strength steel, it is desirable to take advantage of its high strength and use a thinner section, not only for saving weight but also for the economy as much as possible. However, the corrosion factor must be fully considered. The thinner the steel section, the more attention should be paid to corrosion protection. Some low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but in some cases, take appropriate precautions and can even be used without being coated in the atmosphere.

The deoxidization process of Q345R boiler vessel plate if the type and amount of deoxidizer are controlled to make a certain amount of oxygen remain in the 09CUPTIRE-A steel grade steel, when sufficient amount of strong oxidant is added to make the steel deoxidize well, the co bubble will escape during the solidification process and generate boiling phenomenon, no co bubble will be generated during the solidification of the 09CUPTIRE-A steel grade steel, the steel used for the pressure vessel of the killed steel is called the killed steel, this kind of steel is called the boiling steel.

S500MC steel plate/sheet,EN10149 S500MC steel plate/sheet, under EN standard, we can regard S500MC steel plate/sheet as high yield strength steels for cold-forming steels. 09CUPTIRE-A steel grade, EN10149 S500MC is mainly used as high yield strength steels for cold-forming steels. The EN10149 S500MC steel is equivalent to SEW092 QStE500TM, NFA E490D, UNI FeE490TM and ASTM X70XLK steel grades.

Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
