The main materials are high-quality structural steel and low-alloy heat-resistant steel. Commonly used boiler steel is low-carbon killed steel smelted by open hearth or low-carbon steel smelted by electric furnace. The carbon content Wc is in the range of 0.16%-0.26%. Since the boiler steel plate works under high pressure at medium temperature (below 350ºC), in addition to high pressure, it is also subjected to impact, fatigue load and corrosion by water and gas. The performance requirements for boiler steel are mainly good welding and cold bending. performance, certain high temperature strength and alkali corrosion resistance, oxidation resistance, etc. Boiler steel plates generally work under medium and high temperature and high pressure conditions. In addition to high temperature and pressure, they are also subjected to impact fatigue loads and corrosion by water and gas. The working conditions are poor. Therefore, boiler steel plates must have good physical and mechanical properties. Processability to ensure the safety of equipment use
The main purpose
Widely used in petroleum, chemical, power station, boiler and other industries, used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, Equipment and components such as high-pressure water pipes and turbine volutes of hydropower stations
