Itsinda 400 ryuruhererekane rwibyuma bitagira umwanda mubisanzwe bifite chromium 11% na manganese yiyongera 1%, hejuru yitsinda 300. Uru rukurikirane rw'ibyuma rudafite ingese ikunda kwibasirwa n'ingese no kwangirika mubihe bimwe na bimwe nubwo kuvura ubushyuhe bizabakomera. Urukurikirane 400 rwibyuma bitagira umwanda bifite karubone nyinshi, ikabiha imiterere ya kristaline ya martensitike itanga ibicuruzwa byanyuma hamwe nimbaraga nyinshi kandi birwanya kwambara cyane. Ibyuma 400 byuruhererekane bikunda gukoreshwa mubikoresho byubuhinzi, gucecekesha gaze ya gaz turbine, ibyuma, imashini ya moteri, nibindi byinshi.
