What is ENiCrMo-13-AW?
ENiCrMo-13-AW is ENiCrMo-13 heat treated to AW — standard supply/qualification condition: deposit used directly in the as-welded state, no PWHT required for corrosion service. ENiCrMo-13-AW has a yield strength of 480 MPa (69.6 ksi) and a tensile strength of 745 MPa (108 ksi) — stronger than 70% of nickel alloy grades. Elongation at break is 40% and the elastic modulus is 210 GPa (30.5 Msi). ENiCrMo-13-AW has a density of 8.6 g/cm³ (0.311 lb/in³), heavier than 67% of nickel alloy grades. It melts at 1,310°C (2,390 °F).

Working with ENiCrMo-13-AW
Is ENiCrMo-13 easy to machine?
Deposit machines like Alloy 59 base metal: low speeds, heavy positive-rake carbide, rigid setup and flood coolant to fight work hardening and gumming.
Can ENiCrMo-13 be welded?
DCEP, stringer beads, low heat input (<1.5 kJ/mm), interpass ≤150 °C, weave ≤3× core diameter; redry electrodes 250–300 °C and keep in a hot quiver.
Can ENiCrMo-13 be formed, bent or molded?
Not a wrought product — formability applies only to the deposited bead; grind-and-blend rather than cold work the weld.
What surface finishes work on ENiCrMo-13?
Grind flush with clean Ni-dedicated abrasives, then pickle/passivate or electropolish to remove heat tint and restore full pitting resistance.

ENiCrMo-13-AW — frequently asked
What is ENiCrMo-13-AW used for?
ENiCrMo-13-AW is typically used for chemical processing repairs, flue gas desulfurization welding and field maintenance of Ni-Cr-Mo vessels. In short: alloy 59 covered electrode; corrosion rating 96; overlay-capable deposit.
What is the yield strength of ENiCrMo-13-AW?
ENiCrMo-13-AW has a typical yield strength of 480 MPa (69.6 ksi) and a tensile strength of 745 MPa (108 ksi) — stronger than 70% of nickel alloy grades. Strength varies by condition: see the 2 listed tempers.
Is ENiCrMo-13-AW easy to machine?
Not especially — machinability is rated poor (20/100, better than 53% of nickel alloy grades). Deposit machines like Alloy 59 base metal: low speeds, heavy positive-rake carbide, rigid setup and flood coolant to fight work hardening and gumming.
Can ENiCrMo-13-AW be welded?
Yes — weldability is rated excellent (85/100). DCEP, stringer beads, low heat input (<1.5 kJ/mm), interpass ≤150 °C, weave ≤3× core diameter; redry electrodes 250–300 °C and keep in a hot quiver.
What surface finishes work on ENiCrMo-13-AW?
Grind flush with clean Ni-dedicated abrasives, then pickle/passivate or electropolish to remove heat tint and restore full pitting resistance.
Can ENiCrMo-13-AW be formed, bent or molded?
Not a wrought product — formability applies only to the deposited bead; grind-and-blend rather than cold work the weld.
What is the maximum service temperature of ENiCrMo-13-AW?
ENiCrMo-13-AW is rated for continuous use to about 450°C (842 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between ENiCrMo-13-AW and ENiCrMo-13-SA?
AW is the default condition — standard supply/qualification condition: deposit used directly in the as-welded state, no PWHT required for corrosion service. SA: pick when the fabrication is solution annealed after welding (e.g. small vessels, clad plate) to homogenize segregation and maximize corrosion resistance. Yield strength is 480 MPa in AW versus 400 MPa in SA.
