European Steel Designation	AISI Nearest Fit	Service Properties	Applications
1.4016 X6 Cr 16	430	Lower Chrome and the absence of Nickel result in a lower work hardening rate than austenitic grades resulting in a lower breaking strength especially when fully cold rolled. Most often used in the annealed (soft) condition this grade has good formability and a moderate corrosion resistance. Unlike the austenitic grades the ferritic steels respond strongly to a magnet. When cold rolled and annealed the surface finish is reflective. It is significantly lower cost than the austenitic grades. Can only be hardened by cold work.	Automotive and domestic appliance trim, domestic sinks, domestic washer drums, floppy disc hub and pressings generally.
1.4113 X6 Cr Mo 16-1	434	This grade has improved corrosion resistance compared with 1.4016 due to the addition of 1.0% Molybdenum.	A favourite choice for up market automotive trim.Applications are found where there is a need to retain a good appearance
1.4605 X2 Cr Al Ti 18-2	type 18 - SR	This steel has similar characteristics to the base ferritic grade 1.4016 and with improved high temperature resistance to scaling and increased electrical resistance.	It is used in heat exchangers, electrical resistance applications such as dynamic brakingand overload resistors.
