Standard Specification for Niobium-Hafnium Alloy Ingots
STANDARD published on 1.4.2025
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers hafnium alloyed niobium ingots prepared by vacuum- or plasma- arc melting or electron-beam furnace melting, or a combination of these methods, to produce consolidated metal for processing to various mill shapes. The material shall conform to the required chemical composition prescribed. Each ingot should be tested for soundness by non-destructive test methods, such as dye penetrant and ultrasonic testing. Each ingot shall be tested for chemical composition in at least three positions along the length of the ingot.
