Introduction of boiler and pressure vessel steel plate:
Boiler and pressure vessel steel refers to the special steel used for making pressure vessel and boilers. Boiler and pressure vessel steel is usually required to have certain strength. In order to meet different design and manufacturing requirements, there are a series steel grades available according to the strength, including carbon steel series and low alloy high strength steel series.
Boiler and pressure vessel steel plate has strict requirements on chemical composition and quality control, so as to ensure its minimum strength, enough toughness, and suitable for welding. The boiler and pressure vessel steel plate must meet the special performance requirements of high temperature and low temperature in some conditions. Heat treatment of boiler and pressure vessel steel plate are: hot rolling, normalizing, controlled rolling, annealing, tempering + normalizing, tempering.
