FAQ About ASTM A513 and ASTM A519
Is ASTM A519 stronger than ASTM A513?
Yes. ASTM A519 seamless tubing generally offers higher tensile strength, yield strength, and fatigue resistance because it contains no welded seam.
Can ASTM A513 replace ASTM A519?
In non-critical applications, ASTM A513 can often replace ASTM A519 and reduce costs.
However, for hydraulic cylinders, pressure systems, and high-stress mechanical components, ASTM A519 is usually required.
Is ASTM A519 seamless or welded?
ASTM A519 is a seamless mechanical tubing specification.
What is the most common ASTM A513 grade?
The most widely used grades are:
ASTM A513 1010
ASTM A513 1020
ASTM A513 1026
What is the most common ASTM A519 grade?
Popular grades include:
ASTM A519 1020
ASTM A519 1026
ASTM A519 4130
ASTM A519 4140
Summary
ASTM A513 and ASTM A519 are both important standards for mechanical tubing, but their applications differ.
ASTM A513 offers excellent dimensional control and shape flexibility, making it ideal for structural and general mechanical applications. ASTM A519 features seamless construction, superior strength, higher fatigue resistance, and enhanced pressure resistance, making it suitable for demanding engineering applications.
