What are stainless steels
Iron-base alloys containing sufficient CHROMIUM to form a stable passive film on the surface. 10.5% is the qualifying concentration of Cr for an alloy to be called Stainless Steel. Stainless steels also exhibit remarkable resistance to oxidation at elevated temperatures.
Stainless Steel Grades
304L:Basic Austenitic Grad
Most economical of austenitic grade.
304LSC: Enhanced Corrosion Resistance
This is a tin-modified version of 304L alloy having all the characteristics of 304L, except for improved corrosion resistance while sintered at 1120℃.
410:Martensitic Grade
The martensitic form has the lowest corrosion resistance of all P/M stainless steel grades. Low cost.
316L: Austenitic Grade
This alloy offers better corrosion resistance and machinability than 304L. With careful processing it can meet the corrosion resistance requirement of the more demanding applications.
What makes stainless steels “Stainless”
With sufficient chromium(>10.5%), the steel is able to form a protective film on the surface (passivate) in aqueous environments
THE FILM:
Tin-100-500nm
Hydrous oxides (M-xOH), needs Oxygen
Dynamic and self-healing
Rich in Cr, Mo and Si
Damaged by chloride ions, low pH
Weak near oxides, precipitates, crystal defects
STABILIGY of the film determines corrosion resistance
Why Use Stainless Steel
Corrosion resistance (Cosmetic & Functional)
Oxidation resistance
Appearance (luster & color)
Elvevated temperature mechanical strength
Room temp mechanical strength, toughness
Low cost wear resistant material
Magnetic behavior with ferritic
