Abstract
AISI 301LN is a metastable austenitic stainless steel that offers an excellent
combination of high strength and ductility. This stainless grade is currently used in applications
where severe forming operations are required, such as automotive bodies. When these
metastable steels are plastically deformed at room temperature, for example by cold rolling,
austenite transforms to martensite and, as a
result, yield strength increases but ductility is
reduced. Grain refinement is the only method that allows improving strength and ductility
simultaneously. Several researchers have demonstrated that fine grain AISI 301LN can be
obtained by heat treatment after cold rolling. This heat treatment is called reversion because it
provokes the reversion of strain induced martens
ite to austenite. In the
present work, sheets of
AISI 301LN previously subjected
to 20% of cold rolling reduction were treated and a refined
grain austenitic microstructure was obtained. M
echanical properties, including fatigue limit,
were determined and compared with those corres
ponding to the steel both before and after the
cold rolling.
