(S)A516 Gr.70 is a kind of material of boiler steel plate, with different grades (S) A516 Gr.55, (S) A516 Gr.60, and (S) A516 Gr.65, which are widely used in petroleum, chemical, power station, boiler and other industries.
Boiler and pressure vessel steel plate is used to make equipment and components such as reactors, heat exchangers, separators, spherical tanks, gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes for hydropower stations, and turbine volutes.
(S)A516 Gr.70 is one of the self-developed products. The steel plate meets the technical requirements of NACE-MR0175 oil field equipment for anti-sulfide stress cracking metal materials and has passed HIC SSC test.
This boiler steel is the first in China and leads the world. (S)A516 Gr.70 complies with the requirements of
(ASME) ASTMA516 / A516M standard, and has been fulfilled to meet the needs of oil and gas with high content of sulfur and hydrogen, reduce sulfur and hydrogen corrosion, reduce equipment maintenance and increase equipment life.
The boiler steel plate has the following characteristics: good impact resistance, small temperature deformation, good welding performance, good fatigue resistance, good anti-laminarity, micro-alloying, high purity, low carbon equivalent and strong sulfur and hydrogen resistance . The product has good dimensional tolerances and surface quality, and is now widely used in major chemical sites.
