Astm B517. Standard specification for welded tubes and pipes of Nickel, chromium, iron (UNS N06600, UNS N06603, UNS N06025, and UNS N06045).
The Relevance B517
American society for testing and materials (ASTM). The current version in 2005. Initially, the standards approved at the beginning of the XX century. Last previous edition approved in 2000. Astm B517 specification establishes the requirements for welding pipes made from chromium-Nickel alloys., .
This is the basic alloy used in cases when high resistance to corrosion, simultaneously with the endurance of high temperatures. Russian analogues of Inconel 600 (Astm B517) — alloys KHN60VT and KHN78T (GOST 5632).
Chemical composition of Alloy 600 (ASTM B517)
The Nickel gives the alloy good resistance in alkaline solutions. The alloy is insensitive to stress corrosion cracking caused by chloride ions. And the presence of 14−17% Cr provides a neutral reaction in sulfuric and acidic media at high temperatures.
|Tensile strength||95 ksi||655 MPa|
|Yield strength (0.2% deviation)||45 ksi||310 MPa|
The combination of good mechanical properties with high strength, easy workability make this a highly versatile alloy.
