Boiler steel plates mainly refer to the materials used to manufacture superheaters, main steam pipes and heating surfaces of boiler fire chambers. The performance requirements for boiler steel are mainly good welding performance, certain high temperature strength and alkali corrosion resistance, oxidation resistance and so on. Commonly used boiler steels are low carbon killed steel smelted by open hearth or low carbon steel smelted by electric furnace, and the carbon content Wc is in the range of 0.16%-0.26%. When manufacturing high-pressure boilers, pearlitic heat-resistant steel or austenitic heat-resistant steel is used. In recent years, ordinary low-alloy steels have also been used to build boilers, such as 12 manganese, 15 manganese vanadium, 18 manganese molybdenum niobium, etc.
(1) The main steel grades of boiler plates are: 20g, 16Mng, 15CrMoVg, 19Mng, 22Mng
(2) The main steel grades of plates for pressure vessels are: 20R, 16MnR, 15MnNbR, 15MnVNR
(3) Executive standards: GB713-1997, GB6654-1996
As boiler steel plate is an important product with strict safety and reliability requirements and high manufacturing technology difficulty, the material must have the following main characteristics:
The material has high yield strength performance in a certain temperature range (medium and normal temperature and high temperature);
The material has sufficient toughness, and no brittle failure accident will occur during manufacture or use;
The material has a small strain aging sensitivity, especially in the corresponding working temperature region, a certain value of aging impact energy must be guaranteed;
The material has low notch sensitivity, which can prevent steel cracks in welding, opening, and local stress concentration areas;
The material has good welding performance;
The material has a good microstructure, and white spots and cracks are not allowed.
