ASTM A513
ASTM A513 low carbon ERW steel tube is a cost-effective welded mechanical tubing product designed specifically for truck exhaust system applications. This tubing is ideal for straight exhaust sections, intermediate pipes, tailpipe assemblies, muffler inlet/outlet tubes, and fabricated exhaust connectors.
Manufactured from low-carbon steel strip using electric resistance welding, these tubes feature controlled OD, wall thickness, weld seam condition, straightness, and surface finish to support bending, expanding, cutting, welding, and exhaust pipe assembly operations.
| Item | Description |
|---|---|
| Material | Low carbon ERW steel tube |
| Standard | ASTM A513 / ASTM A513M |
| Typical grades | MT 1010, MT 1015, MT X 1015, MT 1020, MT X 1020; other grades such as 1008, 1010, 1020, 1026 available by order |
| Manufacturing process | Electric Resistance Welded, made from hot-rolled or cold-rolled steel strip |
| Outside diameter | 19-381 mm; ASTM A513 hot-rolled ERW round tubing range up to 12.7-380 mm |
| Wall thickness | 1.65-16.5 mm for hot-rolled ERW range; thinner cold-rolled ERW wall sizes available by design |
| Length | 1-12 m, fixed length or random length; customized cut-to-length available |
| Tolerance range | OD, wall thickness, length, squareness, and straightness according to ASTM A513 order requirements |
| Straightness | Commercial straightness or tighter straightness by agreement; suitable for automatic cutting and bending lines |
| Surface condition | Oiled, dry, bright, black, pickled, or coated; protective coating available for storage and shipment |
| Weld flash condition | Inside flash controlled, removed, or as-welded according to purchase order |
| Heat treatment | As-welded, stress-relieved, normalized, or other thermal condition by agreement |
| End finish | Plain end, deburred end, square-cut end, or chamfered end |
| Main application | Truck exhaust system pipe |
| Characteristic | Technical Description |
|---|---|
| Low-carbon formability | MT 1010 carbon range 0.02-0.15%; 1010 carbon range 0.08-0.13%; suitable for bending, expanding, flaring, and exhaust pipe forming |
| Controlled manganese range | MT 1010 Mn 0.30-0.60%; MT X 1020 Mn 0.70-1.00%; higher Mn grades provide improved strength while maintaining weldability |
| ERW weld seam | High-frequency electric resistance welded seam; flash condition can be specified to improve internal flow and reduce forming defects |
| Exhaust fabrication suitability | Supports mandrel bending, end forming, muffler connection, welded brackets, and pipe assembly |
| Dimensional capability | Regular OD range 19-381 mm and wall thickness 1.65-16.5 mm match common medium-duty and heavy-duty truck exhaust pipe requirements |
| Surface process compatibility | Can be supplied oiled, pickled, phosphated, aluminized, painted, or coated according to downstream exhaust system requirements |
| Traceable quality | Heat analysis, product analysis, dimensional inspection, and mechanical testing can be supplied according to purchase order |
| Professional Concern | Our Solution |
|---|---|
| Weld seam quality during bending and expansion | Tubes can be ordered with controlled weld flash condition, deburred ends, and inspection of OD, wall thickness, straightness, and seam position. This helps reduce cracking, wrinkling, and local thinning during mandrel bending or exhaust pipe end forming. |
| Material selection for truck exhaust fabrication | For easy forming, MT 1010 or 1010 is recommended. For higher strength pipe sections, MT 1020, MT X 1020, or 1026 can be selected. Grade, thermal condition, and mechanical values can be matched to the customer's bending radius, expansion ratio, and welding process. |
| Stable supply for exhaust pipe production lines | Tubes can be supplied in 1-12 m lengths, fixed cut lengths, bundled packaging, and protected surface condition. Heat number traceability, MTC, dimensional report, and optional NDT can be provided for batch production control. |
