What is ENiCrFe-1?
ENiCrFe-1 (W86132) is an earlier-generation Ni-Cr-Fe covered electrode in the AWS A5.11 family, used for welding and repair of Alloy 600 and related heat-resistant nickel base metals. Deposits give about 380 MPa yield, 620 MPa tensile and 38 % elongation at 185 HB (90 HRB), with service to 815 °C and a corrosion rating of 72. It has largely been superseded by ENiCrFe-3, whose slag releases more freely, but it is still called out in legacy repair, furnace and nuclear maintenance procedures. Use ENiCrFe-3 for new work unless the qualified procedure specifies ENiCrFe-1. ENiCrFe-1 has a density of 8.4 g/cm³ (0.303 lb/in³), heavier than 57% of nickel alloy grades. It melts at 1,330°C (2,426 °F). ENiCrFe-1 has a yield strength of 380 MPa (55.1 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 53% of nickel alloy grades. Elongation at break is 38% and the elastic modulus is 207 GPa (30 Msi).

Working with ENiCrFe-1
Is ENiCrFe-1 easy to machine?
Weld deposit machines like Alloy 600 — low speeds, positive rake carbide, heavy rigid setups and continuous feed to avoid work-hardened glazing; grinding is often preferred for weld dressing.
Can ENiCrFe-1 be welded?
SMAW with DCEP, short arc, stringer or slight weave (≤3× core dia.), low heat input and interpass ≤150 °C; keep electrodes dry (re-bake ~300 °C) and remove slag fully between passes as ENiCrFe-1 slag releases less freely than ENiCrFe-3.
Can ENiCrFe-1 be formed, bent or molded?
Not a wrought product; deposited metal is ductile (≈38 % elongation) and tolerates cold straightening/peening of weldments but work-hardens rapidly.
ENiCrFe-1 chemical composition (wt %)
Limits by weight percent from the governing specification, written the way the spec states them — a single maximum for impurities, a range for alloying elements, and the base element as balance. Nominal is the typical mid-range value.

What surface finishes work on ENiCrFe-1?
Pickle or mechanically clean weld to remove oxide/slag before service; not anodisable — passivate or electropolish for high-purity and nuclear cleanliness requirements.

ENiCrFe-1 — frequently asked
What is ENiCrFe-1 used for?
ENiCrFe-1 is typically used for alloy 600 vessel repair, high-temperature furnace component welding and legacy nuclear component maintenance. In short: legacy Alloy 600 electrode; 815 °C service deposit; superseded by ENiCrFe-3.
What is the yield strength of ENiCrFe-1?
ENiCrFe-1 has a typical yield strength of 380 MPa (55.1 ksi) and a tensile strength of 620 MPa (89.9 ksi) — weaker than 53% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ENiCrFe-1 easy to machine?
Not especially — machinability is rated poor (25/100, better than 76% of nickel alloy grades). Weld deposit machines like Alloy 600 — low speeds, positive rake carbide, heavy rigid setups and continuous feed to avoid work-hardened glazing; grinding is often preferred for weld dressing.
Can ENiCrFe-1 be welded?
Yes — weldability is rated very good (78/100). SMAW with DCEP, short arc, stringer or slight weave (≤3× core dia.), low heat input and interpass ≤150 °C; keep electrodes dry (re-bake ~300 °C) and remove slag fully between passes as ENiCrFe-1 slag releases less freely than ENiCrFe-3.

Can ENiCrFe-1 be formed, bent or molded?
Not a wrought product; deposited metal is ductile (≈38 % elongation) and tolerates cold straightening/peening of weldments but work-hardens rapidly.
What is the maximum service temperature of ENiCrFe-1?
ENiCrFe-1 is rated for continuous use to about 815°C (1,499 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ENiCrFe-1-AW and ENiCrFe-1 PWHT?
AW is the default condition — standard supplied/qualified condition: properties of the as-deposited all-weld-metal per AWS A5.11 test assembly. PWHT: choose when the joint must follow a code-mandated PWHT of the ferritic base metal or requires residual-stress reduction; ductility rises slightly, strength drops marginally. Yield strength is 380 MPa in AW versus 360 MPa in PWHT.
How much does ENiCrFe-1 cost?
ENiCrFe-1 is a high-cost nickel alloy ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
