Delivery normalization-20 impact can also be controlled rolling treatment or normalizing treatment of the steel plate according to the requirements of the manufacturer or design.
Q370R belongs to the domestic brand, is a boiler and pressure vessel plate steel plate is a brand that appeared after the GB713-2014 standard was released, the old standard is 15MnNbR
Delivery status: normal
Wuyang steel plate on the container plate default: three-level flaw detection, according to special requirements, can be customized two and one, other steel mills do not default to contain three-level flaw detection, if necessary, must be specified, mainly used for the production of pressure vessels.

Production process:
According to the special performance requirements of users, combined with the production conditions of broad and thick plates of Baotou steel, the production process is as follows:
Mixing furnace → hot metal desulfurization → top-bottom double-blown converter smelting →LF refining →RH vacuum cycle degassing → Continuous casting → heating → descaling → roughing → finishing → straightening → Cooling → Cutting → shot blasting → Normalizing → Sampling inspection → judgment → Storage → Delivery
Q370R steel plate use:
Widely used in petroleum, chemical, power station, boiler and other industries, for the production of reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, nuclear reactor pressure shell, boiler bubble, hydropower station high-pressure water pipes, water turbine vortex shell and other equipment and components.
