Working with ERNiCrFe-11-AW
Is ERNiCrFe-11 easy to machine?
Weld deposits machine like Alloy 690 — tough, work-hardening, needs rigid setups, sharp carbide, low speed and heavy positive feed.
Can ERNiCrFe-11 be welded?
Deposit with GTAW/GMAW/hot-wire, stringer beads, low heat input, interpass typically ≤150 °C and clean surfaces to avoid ductility-dip and hot cracking.
Can ERNiCrFe-11 be formed, bent or molded?
Supplied as drawn spooled wire or cut lengths; the alloy is ductile enough for wire drawing but is not a wrought structural product form.
What surface finishes work on ERNiCrFe-11?
Pickle/passivate or lightly grind and buff; no anodizing, and grinding debris must be kept ferrite-free in nuclear service.

ERNiCrFe-11-AW — frequently asked
What is ERNiCrFe-11-AW used for?
ERNiCrFe-11-AW is typically used for alloy 690 tube-to-tubesheet welds, nuclear reactor dissimilar-metal welds and steam generator repairs. In short: best SCC-resistant nickel filler; nuclear-grade Alloy 690 match; restricted availability, documented supply.
What is the yield strength of ERNiCrFe-11-AW?
ERNiCrFe-11-AW has a typical yield strength of 420 MPa (60.9 ksi) and a tensile strength of 690 MPa (100 ksi) — stronger than 62% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is ERNiCrFe-11-AW easy to machine?
Not especially — machinability is rated poor (18/100, worse than 61% of nickel alloy grades). Weld deposits machine like Alloy 690 — tough, work-hardening, needs rigid setups, sharp carbide, low speed and heavy positive feed.
Can ERNiCrFe-11-AW be welded?
Yes — weldability is rated excellent (85/100). Deposit with GTAW/GMAW/hot-wire, stringer beads, low heat input, interpass typically ≤150 °C and clean surfaces to avoid ductility-dip and hot cracking.
What surface finishes work on ERNiCrFe-11-AW?
Pickle/passivate or lightly grind and buff; no anodizing, and grinding debris must be kept ferrite-free in nuclear service.
Can ERNiCrFe-11-AW be formed, bent or molded?
Supplied as drawn spooled wire or cut lengths; the alloy is ductile enough for wire drawing but is not a wrought structural product form.
What is the maximum service temperature of ERNiCrFe-11-AW?
ERNiCrFe-11-AW is rated for continuous use to about 1,000°C (1,832 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrFe-11-AW and ERNiCrFe-11-SA?
AW is the default condition — standard condition for GTAW/GMAW deposits and overlays used in nuclear DMW joints; no PWHT applied to the nickel weld metal. SA: applied to weld overlays or clad components that receive a full solution anneal with the base metal; homogenises the dendritic structure and lowers strength. Yield strength is 420 MPa in AW versus 330 MPa in SA.
