Stainless Steel Strips
are the generic name given to group of corrosion and heat resisting
Steels. These are iron-base alloys containing chromium as the main
alloying element with a minimum of 10.5% to make it resistant to
staining, rusting scaling in most of the corrosive environment. The
complete range of Stainless Steel can be classified into 3 major
categories viz. Austenitic , Ferritic and Martensitic. Austenitic :
This Category of Stainless Steel contains 16 to 26% Chromium and
6 to 22% Nickel. They are non- magnetic and have excellent corrosion
resistance. They are not hardenable by heat treatment. However, they can
develop high strength on cold working. They are identified in the AISI
300 series.
Ferritic :
This category contains 12 to 30% Chromium without any Nickel.
They are ferro-magnetic in nature and generally not hardenable by heat
treatment. They are identified in AISI 400 series.
Martensitic :
This Category contains 11 to 14% Chromium without any Nickel.
They are ferro-magnetic in nature and are hardenable by heat treatment.
They are also identified in the AISI 400 Series.
