Application
ER410NiMo wire is used primarily to weld cast and wrought material of similar chemical composition. It is recommended using preheat and inter-pass temperature of not less than 300ºF. Post weld heat treatment should not exceed 1150ºF, higher temperature may result in hardening.

Deposited Chemical Composition % (Typical)
C = 0.02 Mo = 0.55 P = 0.012
Cr = 11.8 Mn = 0.45 S = 0.009
Ni = 4.50 Si = 0.40

 

Mechanical Properties (R.T.) 
Yield Strength 92,000psi
Tensile Strength 118,000psi
Elongation 20%

Deposited All Weld Metal Properties
Data is typical for ER410NiMo weld metal deposited by Tig using 100% Argon as the shielding gas.

Recommended Welding Parameters
GTAW “Tig Process”
Wire Diameter Amps DCSP Volts Shielding Gas
.035 60-90 12-15 Argon 100%
.045 80-110 13-16 Argon 100%
1/16 90-130 14-16 Argon 100%
3/32 120-175 15-20 Argon 100%

Note: Parameters for tig welding are dependent upon plate thickness and welding position.
Other shielding Gases may be used for Tig welding. Shielding gases are chosen taking Quality, Cost, and Operability into consideration.
