Chemical Composition of Material
Definition of stainless steel(Adopted form Wikipedia)
In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable",
is defined as a steelalloy with a minimum of 10.5% to 11% chromium content by mass.
Stainless steel does not readily corrode, rust or stain with water as ordinary steel does,
but despite the name it is not fully stain-proof, most notably under low oxygen, high salinity,
or poor circulation environments. It is also called corrosion-resistant steel or CRES
when the alloy type and grade are not detailed, particularly in the aviation industry.
There are different grades and surface finishes of stainless steel to suit the environment
the alloy must endure. Stainless steel is used where both the properties of steel
and resistance to corrosion are required.
Surface Finish :
Characteristics and application
The surface brightness and flatness of no2B is better than no2D.
then through a special surface treatment to improve its mechanical properties,
No2B could nearly satisfy comprehensive uses.
Polished with abrasive belt of git#100-#200, have better brightness with
discontinuous coarse stria, used as inner and external ornaments for building,
electrical appliances and kitchen utensils etc.
Polished with abrasive belt of grit #150-#180,have better brightness
with discontinuous coarse stria, but thinner than No3, are used as bathtub
buildings inner and external ornaments electrical appliances kitchen
utensils and food processing equipment etc.
Polished with abrasive belt of grit #150-#320 on the NO.4 finish and has
continuous streaks, mainly used as buildings ornaments elevators,
door of building, frontal plate etc.
Cold rolled, bright annealed and skin-passed,
the product have excellent brightness and good reflexivity like mirror,
kitchen apparatus, ornament etc.
The product have excellent brightness and prefer reflexivity can to be the mirror.
