Description de produit

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.

No leaks, no fin damage, performance consistent. Heat transfer hasn't dropped, so fouling doesn't seem to be a problem yet.
