Abstract

Research on influence of heat treatment parameters by annealing (temperature and time duration) as well as quality of austenitic stainless steel weld joint of dissimilar steel on degree delta ferrite transformation (measured by device for ferrite content measuring dr.Foerster type 1.053)
and inter-granular corrosion rate using Huey test ( ASTM A 262 part C). A pair of basic materials quality in accordance with standards ASTM A387Gr.12 and ASTM A 240 TP 304L was welded by SMAW using austenitic consumable material different quality. Factors plan of experiment 33 has been applied i.e. temperature 650,700,750ºC; time duration 0,2,10 hours and welds quality AWS E309L, AWS E316L, AWS E 308L.
