Abstract
A comparative study was done on the intergranular corrosion resistance of AISI 304 stainless steel and a new austenitic stainless steel curr ently being developed, in which the concentration of nickel is less th an 2%. The austenitic effect of nickel is replaced by other alloying e lements, mainly manganese. The experimental results are discussed acco rding to ASTM A-262, practices C and E (Huey and modified Strauss). A study of both materials under several test conditions was carried out using scanning electron microscopy to analyze the microstructural char acteristics and the attack morphology.
