General principles for selection of stainless steels
The main factor in the selection process for stainless steels is corrosion resistance. Careful consideration of the application should be done to enable a choice of grade with suitable corrosion resistance whilst keeping costs to an economic minimum. Other considerations such as mechanical properties (strength and toughness), physical properties (magnetic permeability) and forming, fabrication and joining methods available should be secondary.

Grade selection to avoid localised forms of corrosion
Appropriate grade selection is a balance between attaining adequate corrosion resistance, whilst minimising cost. Useful aids to material selection include the Outokumpu Stainless Corrosion Handbook and the Nickel Institute's Crevice Corrosion Engineering Guide.
