ASTM A513 Grade 1015
ASTM A513 Grade 1015 is a low-carbon mechanical steel tubing known for its excellent machinability, moderate strength, and superior formability compared to higher carbon grades. Manufactured using the Electric Resistance Welded (ERW) process, A513 Gr 1015 offers a consistent surface finish and precise dimensional tolerances, making it suitable for high-performance mechanical components, automotive parts, fabricated structures, furniture, machinery, and general engineering applications.
The balanced carbon range in Grade 1015 provides improved strength over Grades 1008 and 1010 while maintaining good ductility, weldability, and ease of processing.
Key Features
- Moderate Carbon Content: Offers better strength than 1008/1010 while keeping excellent ductility.
- Excellent Machinability: Ideal for components requiring machining and secondary processing.
- Good Weldability: Compatible with MIG, TIG, and resistance welding processes.
- Superior Formability: Suitable for bending, forming, swaging, flaring, and flattening operations.
- Precision Dimensional Tolerance: Perfect for high-accuracy mechanical and structural applications.
- Smooth Surface Finish: Supports painting, powder coating, galvanizing, and plating.
