High Frequency Welded Finned Tubes ASTM A210 A1 For Air Heat Transfer Equipment
Helical solid fin tubes, also known as HFW finned tubes, are manufactured using a high frequency welding process. HFW finned tubes are widely used in heat exchangers, boilers, air coolers, economizers and other thermal applications.
ASTM A210 This specification covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes.
Grade | C | Mn | P | S | Si |
---|---|---|---|---|---|
A1 | 0.27 | 0.93max | 0.035 | 0.035 | 0.10 |
For each reduction of 0.01% below the specified carbon maximum, an increase of 0.06% manganese above the specified maximum will be permitted up to a maximum of 1.35%.
Grade | Tensile Strength, min | Yield Strength (0.2% Offset, min) |
---|---|---|
A1 | 60ksi (415 MPa) | 37ksi (255 MPa) |
Elongation min. | 30% | Hardness, max |
143 HB | Rockwell: 79 HRB |
Steel 1018/A36 are all materials of low carbon steel/mild steel commonly used in manufacturing and construction.
Properties: good ductility and machinability; moderate strength; can be case-hardened (carburized) for improved surface hardness.
Generally applicable to power stations or large high-temperature equipment in the oil industry:
