Definition of Stainless Steel :
Stainless steel contains chromium (Cr) which will form dense chromium oxide (Cr2O3) membrane
on the surface to prevent continuous corrosion of steel.  It has excellent features such as anti-
corrosion, anti-oxidization, low heat conductivity and good processing properties.
Widely speaking, stainless steel is a specific kind of steel with corrosion resistance and heat
resistance.  The chromium content is between 10.5% - 30%.

GRADE OF STAINLESS STEEL

The following table lists the designation for specific types of 304 and 316 grades of stainless steel
and also provides their compositions.  304 grade often specifies for all general purpose
application. 316 grade is basically a 304 grade enhanced by the addition of 2-3% Molybdenum.
Containing large amounts of Molybdenum (Mo) grade (Type 316) are preferred to use in
corrosion environment, higher seawater resistance than 304, also can perform excellently in all
hot and cold water with chloride contents up to 200ppm.

The low carbon version is designated with "L" after the alloy number (304L or 316L) are
preferred to use when welding is the joining method.
