ASTM A334 Gr. 6 Seamless Alloy Steel Boiler and Heat Exchanger
Tubes
YuHong Group, one of the leading suppliers in China,we supply alloy
seamless steel boiler tubes with high quality to our customers and
have many experiences in exporting.At lower temperatures, the
toughness of the Gr6 steel tube is excellent, and it will not be
brittle due to impact. And it has good corrosion resistance in all
kinds of corrosive media and can effectively prevent the pipeline
from being damaged due to corrosion.
ASTM A334 This specification covers several grades of minimum-wall-thickness, seamless and welded, carbon and alloy-steel tubes intended for use at low temperatures. Some product sizes may not be available under this speci- fication because heavier wall thicknesses have an adverse affect on low-temperature impact properties.

Chemical Composition % Max
| Grade | C | Mn | P | S | Si |
| Gr. 6 | 0.3 | 0.29-1.06 | 0.025 | 0.025 | 0.1 min |
For each reduction of 0.01% carbon below 0.30%, an increase of 0.05% manganese above 1.06% will be permitted to a maximum of 1.35% manganese.
