Working with ERNiCrMo-13-AW
Is ERNiCrMo-13 easy to machine?
Deposit machines like Alloy 59 base metal — low speed, heavy positive-rake carbide, rigid setup and flood coolant; it work-hardens fast so avoid dwelling and interrupted cuts.
Can ERNiCrMo-13 be welded?
Use as filler for GTAW/GMAW/PAW/SAW with 100 % Ar or Ar+He (no CO2/oxidising shielding), stringer beads, low heat input, interpass ≤150 °C and no preheat; back-purge root passes.
Can ERNiCrMo-13 be formed, bent or molded?
Only relevant as drawn wire — high work-hardening rate requires intermediate anneals during drawing; cut lengths are springy and should be straightened, not bent tightly.
What surface finishes work on ERNiCrMo-13?
Pickle or brush-passivate weld heat tint before service; grinding/electropolishing restores the Cr/Mo-rich passive film — never anodise or leave oxide scale in acid duty.

ERNiCrMo-13-AW — frequently asked
What is ERNiCrMo-13-AW used for?
ERNiCrMo-13-AW is typically used for FGD and scrubber systems, sulfuric/phosphoric acid plants and high-purity chemical processing. In short: alloy 59 matching filler; top-tier acid resistance; hardest deposit to machine.
What is the yield strength of ERNiCrMo-13-AW?
ERNiCrMo-13-AW has a typical yield strength of 470 MPa (68.2 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 68% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ERNiCrMo-13-AW easy to machine?
Not especially — machinability is rated poor (15/100, worse than 76% of nickel alloy grades). Deposit machines like Alloy 59 base metal — low speed, heavy positive-rake carbide, rigid setup and flood coolant; it work-hardens fast so avoid dwelling and interrupted cuts.
Can ERNiCrMo-13-AW be welded?
Yes — weldability is rated excellent (90/100). Use as filler for GTAW/GMAW/PAW/SAW with 100 % Ar or Ar+He (no CO2/oxidising shielding), stringer beads, low heat input, interpass ≤150 °C and no preheat; back-purge root passes.
What surface finishes work on ERNiCrMo-13-AW?
Pickle or brush-passivate weld heat tint before service; grinding/electropolishing restores the Cr/Mo-rich passive film — never anodise or leave oxide scale in acid duty.
Can ERNiCrMo-13-AW be formed, bent or molded?
Only relevant as drawn wire — high work-hardening rate requires intermediate anneals during drawing; cut lengths are springy and should be straightened, not bent tightly.
What is the maximum service temperature of ERNiCrMo-13-AW?
ERNiCrMo-13-AW is rated for continuous use to about 550°C (1,022 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrMo-13-AW and ERNiCrMo-13 AW-SA?
AW is the default condition — standard qualification condition: deposit used as welded, no post-weld heat treatment, for corrosion service. AW-SA: pick when the fabrication is solution annealed after welding to homogenise the deposit and restore maximum corrosion resistance for extreme acid duty. Yield strength is 470 MPa in AW versus 360 MPa in AW-SA.
