BBN supply JIS SM490B plates cold bending performance

Hot-rolled steel sheet / cold-rolled steel sheet: Steel ingots or slabs are difficult to deform at normal temperature and difficult to process. They need to be heated to 1100 ° C to 1250 ° C for rolling. This JIS SM490B plates rolling process is called hot rolling. Rolling at room temperature is generally understood as cold rolling. However, from the point of view of metallurgy, the boundary between hot rolling and cold rolling should be distinguished by the temperature of metal recrystallization, that is, rolling below the recrystallization temperature is cold rolling; Rolling above the recrystallization temperature is hot rolling.

Both 20# seamless steel pipe and 20G seamless steel pipe are carbon structural steel with average carbon content of 0.20%. There are big differences in the use standard, chemical composition, mechanical properties and price between JIS SM490B plates, 20# seamless steel pipe and 20G seamless steel pipe, so they must be selected correctly in the design and use, so as to avoid affecting the service life or even causing destructive accidents. The purpose of JIS SM490B plates, GB8162 20# seamless steel pipe is for general structure, the purpose of GB8163 20# seamless steel pipe is for conveying fluid, and the purpose of GB3087 standard 20# seamless steel pipe is for low and medium pressure boiler. 20G seamless steel pipe is used for high pressure steam boiler and pipeline.
