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.
