JIS G3106 SM520C steel material sheet coil used in other structural elements

If A 515 grade 70 pressure vessel plates thick in 50mm or under this thickness, JIS G3106 SM520C steel material, 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.

In the manufacturing process of boiler pressure components, raw materials must undergo complex processing deformation and welding, so the steel used to manufacture the boiler must also have good process performance. All materials JIS G3106 SM520C steel material used to manufacture pressure parts must conform to the relevant national standards for boiler steel. The defects such as delamination, non-metallic inclusion, porosity and looseness in the steel shall be as few as possible, and white spots and cracks are not allowed.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter JIS G3106 SM520C steel material steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
