Application
ER430 is a ferritic stainless steel which offers good ductility in heat treated condition. In addition to the applications of welding similar alloys, it is also used for overlays and thermal spraying.

Deposited Chemical Composition % (Typical)
C = 0.07	Mo = 0.10	P = 0.014
Cr = 16.5	Mn = 0.44	S = 0.01
Ni = 0.25	Si = 0.36

 

Mechanical Properties (R.T.)
Yield Strength	59,000psi
Tensile Strength	77,500psi

Deposited All Weld Metal Properties
Data is typical for ER430 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.
