ASTM A334 Gr6 Seamless Carbon Alloy Steel Low Fin Tubes For Low Temperature Service
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 specification because heavier wall thicknesses have an adverse affect on low-temperature impact properties.
The advantages of ASTM A334 Grade 6 Tubes in low-temperature service are directly tied to their specific chemistry and manufacturing process, making them a superior choice for critical cryogenic and arctic applications.
Advantages:
1.Exceptional Low-Temperature Toughness: The addition of nickel ensures the steel retains its ductility and ability to deform plastically, absorbing energy instead of fracturing catastrophically.
2.Superior Resistance to Brittle Fracture: A334 Gr. 6 its fine-grained microstructure and nickel content allow it to arrest the propagation of cracks, ensuring that any flaw that develops will not lead to a runaway failure of the entire system.
3.Good Strength at Low Temperatures: A334 Gr. 6 maintains adequate mechanical strength in cold service.
Chemical Composition (%)
| Grade | C | Mn | P | S | Si |
| Gr.6 | 0.30 | 0.29-1.06 | 0.025 | 0.025 | 0.10 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.
