200 series stainless steels high manganese (CrMn)
A disadvantage of CrMn grades is that the lower nickel content means a higher risk of delayed cracking after deep drawing A quirk of the conventional 200 series higher manganese grades is that they do not become magnetic when they are heavily cold worked, hence their suitability for use as end rings in electrical generators AuSTENITIC ChroMIuMMANGANESE STAINlESS STEElS – A EuropEAN ApproACh replacing nickel in austenitic stainless steels by adding manganese has been considered for over 50 years The purpose is to reduce the impact of nickelprice fluctuations on the alloy surcharge This has resulted in the development of the socalled 200 series TheseAustenitic ChromiumManganese Stainless Steels – A Hadfield steel cannot be used, because such a high carbon concentration (ie 12%wt) implies a very poor weldability, and high strength of steel is needed, the simultaneous stabilization of the austenite and the high strength are obtained by addition of manganese and chromium 2–4) The manganeseHardening Optimization of High Chromium
Hardening Optimization of High Chromium

Evaluation of effect of chromium on wear
Chromium alloyed high manganese steels showed superior wear resistance compared with plain Hadfield steels where corrosion, abrasion, and combined impactabrasion conditions prevailed Such conditions required a high surface hardness Plain Hadfield steel showed superior wear resistance in conditions where pure impact wear is encountered Chromium (Cr)/nitrogen (N) alloying can enhance the yield strength of highmanganese (Mn) steels This work investigated the mechanical properties of a highMn twininduced plastic (TWIP) steel with 63% Cr and 02% N by tensile testing in an ambient atmosphere and impact testing at –196 °CThe yield strength of the highMn steel was improved significantly with Cr/N alloying and an Enhancement of yield strength by chromium/nitrogen The inner very thin, finegrained part of the scale contained manganese, chromium and iron sulfides and oxides, the intermediate layer was built mainly of the MnCr 2 O 4 spinel while MnO was the predominant constituent of the outer scale layer According to the gravimetric measurements, after an initial incubation period, the oxidation of steel High Temperature Corrosion of
