Its unique chemical composition, superior mechanical properties, after precision heat treatment and meet the requirements of low temperature impact test, so that it has outstanding advantages in ensuring equipment safety and reliable performance.

 

1.Chemical Composition

 

ASTM A302/A302M A302 GradeB(A302GrB) The chemical composition of boiler and pressure vessel steel plates mainly includes elements such as iron, carbon, manganese, phosphorus and sulfur. The carbon content is usually between 0.15% and 0.25%, and the manganese content is between 0.70% and 1.60%. These elements are precisely proportioned to give the steel excellent strength, toughness and corrosion resistance.

 

2.Mechanical Properties

 

ASTM A302/A302M A302 GradeB(A302GrB) Boiler and pressure vessel steel plates demonstrate excellent mechanical properties. Its tensile strength is usually greater than 480MPa, and the yield strength is about 270MPa. These characteristics enable the steel to withstand complex working stresses and maintain stable performance under various extreme conditions.

 

3.Heat Treatment State

 

ASTM A302/A302M A302 GradeB(A302GrB) Boiler and pressure vessel steel plates undergo a specific heat treatment process, including steps such as heating, holding and cooling, to optimize their internal crystal structure and further improve their mechanical properties and corrosion resistance. The steel plate after heat treatment has better toughness and fatigue resistance, and can adapt to long-term high temperature work.

 

4. Low Temperature Impact Test

 

ASTM A302/A302M A302 GradeB(A302GrB) Boiler and pressure vessel steel plates must pass low temperature impact tests to ensure that they maintain good impact toughness and fracture resistance at low temperatures. This test is crucial for assessing the performance of steel at extreme temperatures, helping to ensure the safe operation of equipment in cold environments.
