Austenitic Stainless Steel grades are characterized by
superior corrosion and oxidation resistance, weld ability, ductility and
toughness compared to ferritic and martensitic Stainless Steel grades for
similar levels of chromium. Austenitic Stainless Steel grades exhibit excellent
resistance to atmospheric corrosion. They effectively withstand attack of
organic acids (e.g. acetic, lactic, citric etc.), exhibit good resistance to
oxidizing acids (e.g. nitric acid) and fair resistance to mineral acids (e.g.
sulfuric acid). Some grades work hardens to a high degree while others have
been developed to minimize this tendency. Work hardening is advantageous in
certain cases where high strength is required. Austenitic Stainless Steel
grades are nonmagnetic in annealed condition but depending on composition, they
may become mildly magnetic when cold worked.
These Stainless Steel grades possess good high temperature
properties such as creep strength and resistance to oxidation or scaling. They
also exhibit excellent low temperature ductility and impact strength.
Austenitic Stainless Steel grades can be readily fabricated by bending,
drawing, spinning, punching, drilling, machining and welding and can be readily
polished to a high finish. These attributes make them very versatile and
popular for diverse applications in a variety of industries. There are two
broad categories of Austenitic Stainless Steel — chrome nickel (300 Series) and
chrome manganese (200 Series). Currently, chrome-nickel is the largest produced
Stainless Steel category globally.
Typical applications for this category include food
processing, chemical plants, pharmaceutical equipment, hospitals, textile,
architectural, building construction, kitchenware, consumer durables etc.
Chrome-manganese Stainless Steel is the fastest growing of
all Stainless Steel categories on account of its high performance to cost
ratio. Its applications include kitchenware, cutlery, sinks, automotive trim,
architectural, buildings, furniture, buses, trains and ornamental tubes.
