W6Mo5Cr4V2(M2) calido ferro involutus per catenas

M2 est series molybdaeni summus celeritatis chalybs, commoda parva carbide inhomogeneitatis et altae duritiae. Facilis ad overheating, temperaturas calefactio stricte compescere, arctiore curationis caloris tutelam. Propter duritiem et fatigabilitatem, usus est in fabricando difficilius incisionis ad materias asciandas. M2 summus celeritas ferro cum carbide orientationis maior est, ita arctiori custodia caloris curationi apta est ad formam vibrationis et onera inpulsa.
