ASTM A210 Gr.A-1 Seamless Carbon Steel Tubes: High-Performance for Heat Exchangers & Boilers
ASTM A210 Gr.A-1 tubes are crafted from high-quality carbon steel, engineered for superior heat transfer and structural integrity in demanding environments. Their chemical composition strictly adheres to ASTM standards:
| Element | Composition (%) |
| Carbon (C) | 0.27-0.34 |
| Manganese (Mn) | 0.70-1.00 |
| Phosphorus (P) | ≤0.035 |
| Sulfur (S) | ≤0.035 |
Designed to withstand thermal cycling and pressure in heat exchangers and boilers, these tubes deliver robust mechanical performance:
| Property | Value |
| Tensile Strength | 415 MPa min |
| Yield Strength | 255 MPa min |
| Elongation | 30% min |
| Maximum Operating Temp | 480℃(896℉) |
For global project compatibility, ASTM A210 Gr.A-1 aligns with these international equivalents:
| Standard | Material Grade | Region |
| ASTM A210 Gr.A-1 | Carbon Steel Seamless | USA |
| DIN 17175 | St45.8/III | Europe |
| JIS G3461 | STB 410 | Japan |
| GB 5310 | 20G | China |
Our ASTM A210 Gr.A-1 tubes undergo precision manufacturing:
- Seamless Production: Hot-rolled from solid billets, ensuring uniform wall thickness and no weak seams.
- Heat Treatment: Normalized to enhance grain structure, improving toughness and heat resistance.
- Surface Finishing: Descaled and polished to reduce fouling in heat exchange applications.
- Quality Testing: 100% hydrostatic testing (at 30% above design pressure) and ultrasonic inspection for defects.
Ideal for heat transfer systems requiring durability and efficiency:
- Heat Exchangers: Chemical processing, oil refineries, and HVAC systems.
- Boilers: Industrial boilers, power plant boilers, and thermal heating systems.
- Pressure Vessels: Where high-temperature fluid transfer is critical.
Superior Heat Transfer: Smooth inner surface minimizes fluid resistance, optimizing thermal efficiency.
Seamless Durability: Eliminates leak risks, critical for high-pressure heat exchange environments.
Cost-Effective: Carbon steel offers excellent performance-to-cost ratio for industrial applications.
Global Compliance: Meets ASTM A210 and equivalent standards, simplifying international project approvals.
Q1: Can these tubes be customized for specific sizes?
A: Yes, we offer diameters from 16mm to 168mm and wall thicknesses from 2mm to 10mm, with cut-to-length options (1-12m).
Q2: Are they suitable for corrosive fluids?
A: For mild corrosion, they perform well. For aggressive media, ask about our optional protective coatings or alloy alternatives.
Q3: What quality documentation is provided?
A: Each shipment includes ASTM A210 certification, mill test reports (MTR), and traceability records.
