Stainless steels containing sufficient nickel maintain the austenite crystal structure over a range from very low to very high temperatures. Hence stainless steel containing 8% or more of nickel is referred to as "austenitic". These alloys are usually referred to as '300 series' alloys, which are ductile, easily welded and workhardened.
