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
