MANUAL FOR SURFACE TREATMENT OF STAINLESS STEELS
www.voestalpine.commainly used where hardness, strength and good wear resis - tance are required (e.g. turbine blades, razor blades and cutlery). Ferritische stainless steels are more corrosion resistant than the martensitic grades, but less resistant than the austeni - tic grades. Like martensitic grades, these are straight chro - mium steels with no nickel.

It can be shown that the maximum INL aris-ing from this effect is given by IR u LMr/(4 O), 2 which, normalized to the full-scale output voltage, is ap-proximately equal to MR LO/(4r ). For example, if M =1024 and R ...
