What is ERNiCrFe-5 PWHT-SR?
ERNiCrFe-5 PWHT-SR is ERNiCrFe-5 heat treated to PWHT-SR — choose when the fabrication is stress-relieved or when the weld follows the base metal's solution/anneal cycle; strength drops slightly, ductility rises. ERNiCrFe-5 PWHT-SR has a yield strength of 340 MPa (49.3 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 63% of nickel alloy grades. Elongation at break is 42% and the elastic modulus is 205 GPa (29.7 Msi). ERNiCrFe-5 PWHT-SR has a density of 8.42 g/cm³ (0.304 lb/in³), heavier than 58% of nickel alloy grades. It melts at 1,330°C (2,426 °F). AW is the default condition FabDigit quotes; PWHT-SR is available on request or by drawing note.

Working with ERNiCrFe-5 PWHT-SR
Is ERNiCrFe-5 easy to machine?
Weld deposits machine like alloy 600 — low speed, heavy positive-rake sharp carbide tools, rigid setup and flood coolant to avoid work hardening; grind flush rather than mill where possible.
Can ERNiCrFe-5 be welded?
Runs on GTAW/GMAW/SAW with Ar or Ar-He shielding; keep interpass below ~150 °C, use stringer beads and low heat input, and clean between passes to avoid oxide entrapment in the sluggish pool.
Can ERNiCrFe-5 be formed, bent or molded?
Supplied as cold-drawn wire; the deposit is highly ductile and can be cold worked or bent after welding, but springback and work hardening are high.
What surface finishes work on ERNiCrFe-5?
Pickle or abrasive-blast plus passivation to remove chromium heat tint before service; no anodizing — electropolish or mechanical polish for hygienic/high-temperature cleanliness.

ERNiCrFe-5 PWHT-SR — frequently asked
What is ERNiCrFe-5 PWHT-SR used for?
ERNiCrFe-5 PWHT-SR is typically used for inconel 600 pressure equipment, incoloy 800H components and petrochemical furnace tubing repairs. In short: stronger than ERNiCr-3; nb-stabilized Alloy 600 filler; multi-process wire (GTAW/GMAW/SAW).
What is the yield strength of ERNiCrFe-5 PWHT-SR?
ERNiCrFe-5 PWHT-SR has a typical yield strength of 340 MPa (49.3 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 63% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ERNiCrFe-5 PWHT-SR easy to machine?
Not especially — machinability is rated poor (25/100, better than 76% of nickel alloy grades). Weld deposits machine like alloy 600 — low speed, heavy positive-rake sharp carbide tools, rigid setup and flood coolant to avoid work hardening; grind flush rather than mill where possible.
Can ERNiCrFe-5 PWHT-SR be welded?
Yes — weldability is rated excellent (92/100). Runs on GTAW/GMAW/SAW with Ar or Ar-He shielding; keep interpass below ~150 °C, use stringer beads and low heat input, and clean between passes to avoid oxide entrapment in the sluggish pool.
What surface finishes work on ERNiCrFe-5 PWHT-SR?
Pickle or abrasive-blast plus passivation to remove chromium heat tint before service; no anodizing — electropolish or mechanical polish for hygienic/high-temperature cleanliness.
Can ERNiCrFe-5 PWHT-SR be formed, bent or molded?
Supplied as cold-drawn wire; the deposit is highly ductile and can be cold worked or bent after welding, but springback and work hardening are high.
What is the maximum service temperature of ERNiCrFe-5 PWHT-SR?
ERNiCrFe-5 PWHT-SR is rated for continuous use to about 980°C (1,796 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ERNiCrFe-5-AW and ERNiCrFe-5 PWHT-SR?
AW is the default condition — default condition: properties of the undiluted deposit in the as-welded state, as qualified per AWS A5.14. PWHT-SR: choose when the fabrication is stress-relieved or when the weld follows the base metal's solution/anneal cycle; strength drops slightly, ductility rises. Yield strength is 400 MPa in AW versus 340 MPa in PWHT-SR.
