SA299 Gr.B steel properties

SA299 Gr.B steel is a carbon-manganese-silicon steel plate for pressure vessels. It is generally used for various welded parts whose working temperature does not exceed 400°C, such as boiler drums, pressure vessels, etc. The steel is required to have a high and medium temperature.
 
The main properties of SA299 Gr.B steel: generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, etc. The steel is required to have high medium temperature strength, good plasticity, heat treatment process performance and welding process performance .
 
Delivery status of SA299 Gr.B steel: normalized or hot rolled. Steel plates with a thickness of less than or equal to 50mm are usually delivered in the rolled state, and can also be supplied and delivered under normalizing, stress relief, or normalizing plus stress relief; steel plates with a thickness greater than 50mm should be normalized heat treatment. It can also add flaw detection standard requirements, flaw detection level requirements, SA299 Gr.B steel alloy element composition control requirements, etc. according to needs.
 

Application range:

SA299 Gr.B steel plate is one of the materials widely used in boiler drums (steam drums) of coal-fired generator sets. It is mainly used in the head and shell of subcritical boiler drum products. Generally used for various welding parts whose working temperature does not exceed 400°C, such as boiler steam drums, pressure vessels, which require the steel to have a high medium temperature.
