The electrode is both austenitic and ferritic. It has high resistance to corrosion. The filler metal has excellent strength even in moderate temperature environments. Welding should be done within the range of 3000 C and -500 C to avoid loss of strength and ductility. The S32305 material has a high nickel, chromium, and molybdenum content which lead to increased resistance to pitting, crevice, and stress cracking corrosion. The hardenability of uns 32205 alloy is enhanced through cold working. The duplex s32205 filler metal does not require preheating and post-welding before use. It is an all-position electrode which makes it easy to use.
