Seamless Tube Library: American ASTM A53A Chemical Composition and Mechanical Properties
The chemical composition and mechanical properties of ASTM A53A are as follows:
Chemical composition (melting analysis)
Carbon (C): ≤ 0.25%
Manganese (Mn): ≤ 0.95%
Phosphorus (P): ≤ 0.05%
Sulfur (S): ≤ 0.06%
mechanical properties
Tensile strength: ≥ 330 MPa (or ≥ 48000 psi)
Yield strength: ≥ 205 MPa (or ≥ 30000 psi)
Elongation: According to standard requirements, it is usually measured under standard test conditions
The above data applies to Grade A materials for seamless steel pipes (Type S) and resistance welded steel pipes (Type E), meeting the requirements of ASTM A53 standard for low-pressure fluid transport and structural applications.
A53A steel pipe belongs to the category of low carbon steel, with good weldability and processability, and is widely used in medium and low pressure industrial scenarios such as construction, machinery manufacturing, and gas transmission.
