ASTM A106 Grade A Carbon Steel Seamless Pipes are made from low carbon steel, typically containing about 0.25% carbon and a combination of 0.27–0.93% manganese. These pipes are often referred to as mild steel pipes due to their low carbon content. ASTM A106 Grade A pipes are known for their cost-effectiveness and ease of fabrication, making them a popular choice in a variety of applications.
These pipes are manufactured according to the ASTM A106 specification and are commercially recognized as carbon steel pipes or mild steel pipes (MS pipes). Although they are softer and more malleable compared to high carbon steel pipes, their surface hardness can be enhanced through processes like carburizing, which involves adding carbon to the surface to increase hardness.
Key Characteristics of ASTM A106 Grade A Pipes:
Low Carbon Content: Offers better flexibility and ease of forming.
Mild Steel: Known for being cost-efficient and easy to shape into various configurations.
Not as Hard as High Carbon Steel: While not as hard, they can be treated to enhance surface hardness if required.
Widely Used: Commonly used in industries where the pipes are subject to low to moderate temperatures and pressures.
