Nickel Alloy Steel Seamless Tube ASTM B407 UNS N08811 Heat Exchangers Gas Oil
Nickel Alloy Steel Seamless Tube ASTM B407 UNS N08811 Heat Exchangers Gas Oil
What is ASTM B407?
ASTM B407 is the standard specification for seamless nickel-iron-chromium alloy steel tubing.ASTM B407 specification includes Incoloy 800 and Incoloy H/HT.ASTMB407 lncoloy 800 seamless tube and ASTM B407Incoloy 800 seamless tube are typically suitable for service temperatures above 1100 F or 593 C. ASTM B407 lncoloy 800 seamless tube and ASTM B407 Incoloy 80OH/HT seamless tube are typically suitable for service temperatures above 1100 F or 593 C. While ASTM B407lncoloy 800H/HT seamless tube and ASTM B407 Incoloy 80OH/HT seamless tube are typically suitable for service temperatures above 1100 F or 593 C where creep and fracture resistance is required. These Lncoloy alloys have a very high resistance to chloride ion stress corrosion cracking and also exhibit good resistance to polysulfate cracking. As a result, these pipes and tubes are very suitable in high temperature petrochemical environments.
