What is the general and specific differences among the sub grades under the ASTM standard?

ASTM A106: This grade is suitable for pipeline systems operating under high temperature and pressure conditions. The sub-grades of A106 include Grade A, Grade B, and Grade C.

• Grade A: This is the lowest strength grade among the A106 sub-grades. It is commonly used for low-pressure applications and does not require heat treatment after the final cold drawing process.
• Grade B: A106 Grade B offers higher strength compared to Grade A, making it suitable for medium-pressure applications. It requires a heat treatment process known as normalization or quenching and tempering after cold drawing.
• Grade C: With even higher strength than Grade B, A106 Grade C is utilized for high-pressure and high-temperature applications. It requires a full annealing or normalizing heat treatment after cold drawing.

ASTM A53: This grade is commonly used for mechanical and pressure applications as well as for ordinary uses in steam, water, gas, and air lines. A53 includes two sub-grades: Type E and Type S.

• Type E: A53 Type E is an electric resistance welded (ERW) grade. It is suitable for welding and coiling operations and is primarily used for mechanical and pressure applications.
• Type S: A53 Type S is a seamless grade known for its superior strength. It is widely used for structural and pressure applications, as well as for conveying fluids. This grade does not require welding and is commonly used in high-temperature environments.
