Compare all 3 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
Solution annealed ~1120 °C + rapid quench after welding | Pick when the fabrication is solution annealed (e.g. overlaid vessels, heavily restrained multipass welds) to dissolve interdendritic Mo/W segregation and restore maximum corrosion resistance. | 400 | 720 | 50 | 180 HB | 1.5 % IACS |

Stress-relieved / thermally aged deposit (500–700 °C exposure) | Reference condition for deposits that see prolonged 500–700 °C service or stress relief — strength rises slightly but toughness and corrosion margin drop from μ/P-phase precipitation; avoid where possible. | 545 | 800 | 25 | 22 HRC | 1.6 % IACS |
What is ENiCrMo-10?
ENiCrMo-10 is a Ni-Cr-Mo-W covered electrode matching Alloy C-22 chemistry (UNS W86022) for shielded metal arc welding of C-22 and related wet-corrosion alloys. As-welded deposits run about 500 MPa yield, 760 MPa tensile, 38% elongation and 210 HB (95 HRB), with service to 650 °C and a corrosion resistance rating of 92/100 covering pitting, crevice attack and stress-corrosion cracking. Deposits work-harden rapidly and need low heat input to control segregation; ENiCrMo-4 (C-276) is the nearest alternative where reducing conditions dominate. ENiCrMo-10 has a density of 8.69 g/cm³ (0.314 lb/in³), heavier than 72% of nickel alloy grades. It melts at 1,357°C (2,475 °F). ENiCrMo-10 has a yield strength of 500 MPa (72.5 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 73% of nickel alloy grades. Elongation at break is 38% and the elastic modulus is 206 GPa (29.9 Msi).

Working with ENiCrMo-10
Is ENiCrMo-10 easy to machine?
Weld caps grind readily but the deposit work-hardens fast — use rigid setups, sharp carbide, low speed/heavy positive feed, flood coolant.
Can ENiCrMo-10 be welded?
Bake electrodes per maker (typically 300–350 °C, 1 h) and keep in a holding oven; DCEP, stringer beads, low heat input (<1.5 kJ/mm) and interpass below 100–150 °C to limit segregation and hot cracking.
Can ENiCrMo-10 be formed, bent or molded?
Not a wrought product; deposits are ductile enough for weld dressing and peening but strongly work-harden.

ENiCrMo-10 — frequently asked
What is ENiCrMo-10 used for?
ENiCrMo-10 is typically used for chemical processing equipment welding, flue gas desulfurization systems and pollution control equipment. In short: matches Alloy C-22 chemistry; oxidising and reducing acids; high pitting and SCC resistance.
What is the yield strength of ENiCrMo-10?
ENiCrMo-10 has a typical yield strength of 500 MPa (72.5 ksi) and a tensile strength of 760 MPa (110 ksi) — stronger than 73% of nickel alloy grades. Strength varies by condition: see the 3 listed tempers.
Is ENiCrMo-10 easy to machine?
Not especially — machinability is rated poor (22/100, better than 64% of nickel alloy grades). Weld caps grind readily but the deposit work-hardens fast — use rigid setups, sharp carbide, low speed/heavy positive feed, flood coolant.
Can ENiCrMo-10 be welded?
Yes — weldability is rated excellent (88/100). Bake electrodes per maker (typically 300–350 °C, 1 h) and keep in a holding oven; DCEP, stringer beads, low heat input (<1.5 kJ/mm) and interpass below 100–150 °C to limit segregation and hot cracking.

Not a wrought product; deposits are ductile enough for weld dressing and peening but strongly work-harden.
What is the maximum service temperature of ENiCrMo-10?
ENiCrMo-10 is rated for continuous use to about 650°C (1,202 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ENiCrMo-10-AW and ENiCrMo-10-SA?
AW is the default condition — standard supply/qualification condition: deposit used as welded, no PWHT — normal for C-22, 59, 686 and dissimilar joints. SA: pick when the fabrication is solution annealed (e.g. overlaid vessels, heavily restrained multipass welds) to dissolve interdendritic Mo/W segregation and restore maximum corrosion resistance. Yield strength is 500 MPa in AW versus 400 MPa in SA.
How much does ENiCrMo-10 cost?
