ASTM B676: Standard Specification for UNS N08367 Welded Tube
ASTM B676 Standard Sizes
ASTM B676 specification covers UNS N08367 welded tube for general corrosion applications. ASME SB676 specification covers the outside diameter and nominal wall tube. ASTM B676 tube sizes covered by this specification are 1/8 to 5 in. (3.2 to 127 mm) in outside diameter and 0.015 to 0.320 in. (0.38 to 8.13 mm), inclusive, of wall thickness.
ASME SB 676 UNS N08367 Welded Tubes Tests
ASTM B676 al6xn tubes shall be subjected to the following tests: hydrostatic test, pneumatic test, eddy current test, ultrasonic test, undergo stretching, flattening, flanging, reverse bending, and non-destructive testing requirements.
AL-6XN Stainless Steel Material Chemical Composition
The al6xn material should consist of carbon, manganese, silicon, phosphorus, sulfur, chromium, nickel, molybdenum, nitrogen, iron and copper.
