Products Description
SA662GrC Pressure Vessel Steel Plate is a kind of high-temperature and high-pressure vessel steel plate, which belongs to carbon manganese silicon steel, with good weldability and workability, suitable for manufacturing various high-pressure vessels, such as boilers, pressure vessels, etc.
Features of SA662GrC Pressure Vessel Steel Plate: 1. good weldability and machinability; 2. excellent high temperature resistance; 3. good corrosion resistance; 4. good low temperature toughness; 5. good fatigue resistance.
The main parameters of SA662GrC Pressure Vessel Steel Plate are as follows: 1. thickness: generally 6mm-200mm; 2. width: generally 1500mm-4000mm; 3. length: generally 3000mm-18000mm; 4. chemical composition: carbon (C) content is 0.19%~0.22% Manganese (Mn) content is 0.80%~1.25%, silicon (Si) content is 0.15%~0.50%, phosphorus (P) content and sulfur (S) content are not more than 0.035%.
pressure vessel steel plate may have the following problems in use:
1. Corrosion: SA662GrC steel plate is prone to corrosion under the harsh environment such as wet, acidic and alkaline, which affects the service life of the steel plate.
2. Fatigue: When subjected to alternating load for a long time, SA662GrC steel plate is prone to fatigue cracking, which affects the strength and stability of the steel plate.
3. Welding quality: If the welding quality of SA662GrC steel plate is not good, it will easily lead to cracks, porosity and other defects in the welding part, which will affect the service life of the steel plate.
4. Hardening: When SA662GrC steel plate is subjected to high temperature for a long time, the phenomenon of hardening will easily occur, which will reduce the plasticity and toughness of the steel plate and affect the service life of the steel plate.
Therefore, when using SA662GrC pressure vessel steel plate, we need to pay attention to the problems of anti-corrosion, anti-fatigue, welding quality and temperature control of the steel plate to ensure the safe and reliable use of the steel plate.
