Working with ENiCrMo-10-AW
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.
What surface finishes work on ENiCrMo-10?
Remove all slag and heat tint by grinding, then pickle or electropolish and passivate to restore the chromium-rich film; no anodizing.

ENiCrMo-10-AW — frequently asked
What is ENiCrMo-10-AW used for?
ENiCrMo-10-AW 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-AW?
ENiCrMo-10-AW 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-AW 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-AW 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.
What surface finishes work on ENiCrMo-10-AW?
Remove all slag and heat tint by grinding, then pickle or electropolish and passivate to restore the chromium-rich film; no anodizing.
Can ENiCrMo-10-AW be formed, bent or molded?
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-AW?
ENiCrMo-10-AW 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.
