Avesta 383 description: AVESTA 383 AC/DC is a highly alloyed fully austenitic electrode with a composition corresponding to AWS E383-17. It is primarily designed for welding ASTM N08028 and similar steels. 383 has a fully austenitic structure which makes it somewhat more sensitive to hot cracking than for example 316L. Welding should be performed taking great care about low heat input and interpass temperature
