| Item | Description |
|---|---|
| Material | Hot-dip aluminized low-carbon steel strip |
| Strip Standard | JIS G3314 SA1D |
| Tube Standard | ASTM A513 ERW mechanical tubing |
| Grade Options | 1008, 1010, 1018, 1020, 1026 |
| Outside Diameter | 5 inch / 127.0 mm; general range 6-350 mm |
| Wall Thickness | 1.0-12.5 mm |
| Length | 1-12 m, customized; maximum 12,000 mm |
| Tolerance Range | OD and WT according to ASTM A513 or agreed drawing tolerance |
| Straightness | Typically ≤1.5 mm/m, or per customer drawing |
| Surface Condition | Aluminized, oiled or dry, bright metallic surface |
| Production | ERW / HFW, optional DOM processing |
| Heat Treatment | No final heat treatment, stress relieved, annealed, or normalized |
| Packing | Hexagonal bundles, anti-corrosion protection, seaworthy packing |
| Characteristic | Technical Value |
|---|---|
| Nominal OD | 5 inch = 127.0 mm |
| Aluminized Layer | Aluminum-silicon hot-dip coating; Type 1 aluminized steel is commonly Al-Si coated |
| Heat Resistance | Aluminized Type 1 steel is effective up to about 1250°F / 677°C; heat reflectivity is reported up to 80% below 800°F / 427°C. |
| Tube Forming | ERW/HFW welded from aluminized strip; weld bead can be controlled by scarfing or internal bead treatment |
| Length Capability | Up to 12,000 mm |
| Recommended Application Fit | Exhaust tube sections requiring heat resistance, corrosion protection, and stable forming behavior |
| Coating Mass Options | Common aluminized coating references include T1-13, T1-25, T1-40, T1-60 under ASTM A463 inventory practice; metric coating mass ranges are often 40-182 g/m² depending on coating class. |
| Procurement Concern | Our Technical Solution |
|---|---|
| Will the aluminized layer crack during bending, expansion, or tube forming? | We control strip grade selection, forming radius, weld heat input, and post-weld sizing to reduce coating damage. For 5 inch exhaust tubes, SA1D deep-drawing quality material is recommended when the part requires bending, flaring, or end forming. |
| Can the 5 inch tube keep stable OD and roundness after welding? | The 127.0 mm tube is produced through ERW/HFW forming, welding, sizing, and straightening. OD, wall thickness, ovality, and straightness can be inspected against ASTM A513 or customer drawings before shipment. |
| How is weld seam reliability controlled for exhaust use? | We control strip edge preparation, weld current, squeeze pressure, bead condition, and leak-related visual inspection. For parts requiring smoother inner diameter, DOM or special smooth ID processing can be selected. |
