Manganese steel,also called Hadfield steel or mangalloy,is a steel alloy containing 12-14% manganese.Renowned for its high impact strength and resistance to abrasion in its hardened state,the steel is often described as the ultimate work hardening steel.2.

to enhance biodegradability led to the use of manganese (Mn) as an alloying element; the Fe-Mn combination was found to exhibit a faster corrosion rate than pure Fe (10-12).However,as with stainless steel,a major limitation of the clinical application of ferrous-based alloys is their high magnetic susceptibility.Since magnetic resonanceCorrosion and Weldability Studies On Chromium-Manganese These studies show that the corrosion resistance of Type 202 (18% Cr-5% Ni-8% Mn-0.10% max.C) stainless steel is comparable to that of Type 304 stainless steel in all but the most strongly oxidizing chemical environments.The weld-ability of the Cr-Mn-Ni and Cr-Mn-N steels is good and equivalent to that of Type 304 stainless steel.Comparison of high MRI T1 signals with manganese Slight increases in the Mn concentrations were found in the caudate,putamen,frontal lobe,and substantia nigra,while a dose-dependent noticeable increase was only found in the globus pallidus.Therefore,the present results indicated that a shortening of the MRI T1 relaxation time corresponded well with the Mn concentration in the globus pallidus after prolonged welding-fume exposure.
