Product Code:SAE AMS7850
Title:Columbium (Niobium) Sheet, Strip, Plate, and Foil
Issuing Committee:Ams G Titanium And Refractory Metals Committee
Scope:This specification covers columbium in the form of sheet, strip, plate, and foil.This material has been used typically for parts requiring exposure to ultra-high temperatures, but usage is not limited to such applications. Applications in oxidizing atmospheres necessitate a protective coating. Although produced in the cold rolled condition, this material is intended to be used in the annealed condition.【英文标准名称】:Gasinfrastructure-Gasinstallationpipeworkwithanoperatingpressuregreaterthan0,5barforindustrialinstallationsandgreaterthan5barforindustrialandnon-industrialinstallations-Part2:Detailedfunctionalrequirementsforco
