If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, 1.8931 S690Q, A515 Grade 70 plates are supplied in the as-rolled condition. Normalizing treatment can be ordered, but those greater than 2 inch (50 mm) in thickness must be delivered in normalizing state. A515 Gr 70plate and sheet are widely used in petroleum, chemical industry, power station, boiler and other industries. It is used to make reactor, heat exchanger, separator, spherical tank, paint tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum.

Try to use 1.8931 S690Q high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the 1.8931 S690Q temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.
