What are the quality requirements of boiler structural 12Cr2Mo1R

The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of boiler structural 12Cr2Mo1R, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.

"Pressure Test Upon completion of vessel construction, there are three pressure tests you'll need to be aware of: Hydrostatic A Hydrostatic Test is a pressure test that fills the pressure vessel with water while removing the air and pressurizing the system up to 1.3 times the designed pressure limit (adjusted for differences in the design state and the test state)."

We are a popular factory, supplier and wholesaler of mild steel plates and alloy steel plates in all over the globe. We follow all standards and specifications of boiler structural 12Cr2Mo1R boiler steel plate, structural steel plate, shipbuilding steel plates and corten steel in different types. We manufacture and supply steel plates, steel section and steel structures according to customer’s demand. The company also focus on providing customers with boiler structural 12Cr2Mo1R high-end steels and competitive price.

The production process of hot-rolled steel plate and cold-rolled steel plate is different. Hot rolled steel plate is rolled at high temperature, and cold rolled steel plate is rolled at normal temperature. Generally speaking, cold rolled steel plate has better strength and hot rolled steel plate has better ductility. The thickness of boiler structural 12Cr2Mo1R cold rolling is generally smaller, and that of hot rolling can be larger. The surface quality, appearance and dimension accuracy of cold rolled steel plate are better than that of hot rolled steel plate.
