ASTM B163 Inconel 718 Pipe
1. Standard: ASTM B163, ASME SB163
2. Size: 1/2''~12'' OD
3. Thickness: SCH5~SCHXXS
4. Equivalent: UNS N07718, WNR.2.4668, Inconel 718
The defining characteristic of ASTM B163 Inconel 718 is its sluggish age-hardening response. Unlike older nickel superalloys that harden spontaneously during welding or cooling-often resulting in catastrophic post-weld strain-age cracking-718 remains highly manageable through its fabrication lifecycle.
