Selection of
Stainless Steels
•
The selection of
stainless steels may be based on corrosion resistance, fabrication
characteristics, availability, mechanical properties in specific temperature
ranges and product cost.
•
However,
corrosion resistance and mechanical properties are usually the most important
factors in selection a grade for a given application.
Factors in
Selection
•
A checklist of
characteristics to be considered in selecting the proper type of stainless
steel for a specific application includes:
•
Corrosion
resistance
•
Resistance to
oxidation and sulfidation
•
Strength and
ductility at ambient and service temperatures
•
Suitability for
intended fabrication techniques
•
Suitability for
intended cleaning procedures
•
Stability of
properties in service
•
Toughness
•
Resistance to
abrasion and erosion
•
Surface finish
and/or reflectivity
•
Magnetic
properties
•
Thermal
conductivity
•
Electrical
resistivity
•
Shrpness
(retention of cutting edge)
•
Rigidity
