The VAR process is used on many different materials. Certain applications almost always use a material that has been VAR treated. A list of materials that may be VAR treated include:
*Stainless Steel
*Alloy Steel
**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
**Hastelloy 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.
