Materials and Applications
The VAR process is used on many different materials, however certain applications almost always use a material that has been VAR treated. A list of materials that may be VAR treated include:
- Steel
- 9310
- 4340 & 4330+V
- 300M
- AF1410
- Aermet 100
- M50
- BG42
- Nitralloy
- 16NCD13
- 35NCD16
- HY-100
- HY-180
- HY-TUF
- D6AC
- Maraging steels
- UT-18
- HP 9-4-30
- Titanium
- Ti-6Al-4V
- Ti-10V-2Al-3Fe
- Ti-5Al-5V-5Mo-3Cr
- Invar
- Nitinol
- Nickel superalloys
- Inconel alloys
- Rene alloys
- RR1000
- Zirconium
- Niobium
- Platinum
- Tantalum
- Rhodium
Note that pure titanium and most titanium alloys are double or triple VAR processed. Nickel-based super alloys for aerospace applications are usually VAR processed. Zirconium and niobium alloys used in the nuclear industry are routinely VAR processed. Pure platinum, tantalum, and rhodium may be VAR processed.

Famous quotes containing the words materials and and/or materials:
“Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.”
—David Elkind (20th century)
“If only it were God’s will that printed and written materials have as much influence on the people as the princes and their censors fear! Considering the countless good books we have, the world would have changed for the better a long time ago.”
—Franz Grillparzer (1791–1872)
