Performance:

A. Ferritic stainless steel magentic

B. Ferrtic stainless steel of the themal expansion rate is low ,close to ordinary carbon body

C. Ferrtic heat transfer rate is high ,1.3 to 1.6 times of austenitic stainless steel,even the heat conduction and can improve the efficiency of heat exchange

D. Containing stabilizing element Nb ferritic stainless steel ,have good creep resistnce

E. Ferritic austenitic stainless steel can be more easily than cutting and procssing

F. When cold deformation,ferritic stainless steel deformation recovery is smaller than austenitic stainless steel ,deep drawing forming performance is better than austenitic stainless steel

G. Ferritic stainless steel have high strength of yield

H. Ferritic stainless steel have good uniform corrosion resistance,resistance to pitting and crevice corrosion resistance

I . As cost performance ,ferritic stainless steel haven't contains Ni,so the costes are relatively cheap ,and will not affect by price fluctuation of Ni .
