SA516Gr70 container board Wugang spot can be rolled manufacturers can cut the price of the franchise

One, SA516Gr70 About SA516Gr70 belong to the low-temperature pressure vessel steel plate with the implementation ASME standards. Wugang 2006 R & D, which is different from that at SA516Gr60 of tensile strength. There grades: SA515Gr50, SA515Gr60, SA516Gr65, SA516Gr70 SA516Gr485 performance standards: ASME standard grades as well: A516Gr70 A516MGr70 Standard: ASTM two American, SA516Gr70 chemical composition C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤ 0.035, Si:. 0.13-0.45 [1] three, SA516Gr70 application SA516Gr70 widely used in petroleum, chemical, power plants, boilers and other industries for the production reactors, heat exchangers, separators, tank, gas tank, gas cans, nuclear reactor pressure vessel, boiler drum, liquefied petroleum gas cylinders, high pressure pipe hydropower, water wheels volute and other equipment and components. Four, SA516Gr70 SA516Gr70 development is one of the six Wugang 2006 to develop new products, steel comply with NACE-MR0175 oilfield equipment sulfide stress cracking of metallic materials technology requirements, and through HIC + SSC tests. The steel for the domestic initiative, the international leader. A516Gr70N accord (ASME) ASTMA516 / A516M standard requirements, and complete required to meet the needs of high levels of sulfur and hydrogen gas oil, to reduce sulfur and hydrogen corrosion, reduce equipment maintenance and increase the life of the equipment. The steel having characteristics: good impact resistance, low temperature deformation, good weldability, good fatigue resistance, good anti-cracking performance layered Caesar, micro-alloyed, high purity, low carbon equivalent and strong anti-hydrogen sulfide, product has good dimensional tolerances and surface quality, Henan Shen Chang Iron & Steel Co., Ltd. currently available thickness of 200mm below the plate. General requirements for domestic use more SAGr70 seldom SA516Gr60 because its performance is more common, domestic SA516Gr70, now widely used in the major chemical sites. Five, mechanical properties and chemical elements SA516Gr70 tensile strength of 70 one thousand pounds / square inch that we usually say more than 482. The main element content is C Mn Si, p, s control to determine its performance. Very little other trace elements. American Materials Inspection Association standards, low carbon steel plates for pressure vessels Standard Specification Standard: American ASTM, ASME Standard: This standard is mainly used to improve the notch toughness is important welding pressure vessel steel plate.

(40mm) should be normalized steel. 3. Unless otherwise specified by the demand side, the thickness ≤1.5in, (40mm) steel, when notch toughness requirements, should be normalized. 4. If approved by the demand side, allowing the use of larger than the cooling rate in air to improve the toughness, but as long as the steel sheet then 1100-1300 ° F (595-705 ℃) within the range of tempering.
