ER2209
AWS/ASME SFA-5.9 :DESCRIPTION:
Duplex stainless steel welding wire rod for TIG welding .Its suitable for welding of austenitic-ferritic stainless alloys of 22% Cr 5% Ni 3% Mo types. Weld metal has a high general corrosion resistance. In media containing chloride and hydrogen sulphide the alloy has a high resistance to intergranular, pitting and especially to stress corrosion.
Analysis of wire electrode% :
| S | P | Cu | N | Mo | Ni | Mn | Cr | Si | C |
|---|---|---|---|---|---|---|---|---|---|
| Max0.03 | Max0.03 | Max0.75 | 0.08-0.2 | 2.5-3.5 | 7.5-9.5 | 0.5-2.0 | 21.5-23.5 | Max0.9 | Max0.03 |
Shielding gas: 100% Ar
Operation Information
Adding up to 2% nitrogen (N2) and 20-30% helium (He) to the shielding gas is beneficial and has a positive effect on mechanical properties as well as corrosion resistance. helium increases the arc energy.
Gas flow rate: 4-8 L/Min
Generally no preheating is required. The iterpass temperature and heat input must be controlled.
TYPICAL APPLICATIONS :
It is widely used in offshore industries and chemical and petrochemical processes.
