Morero o ka sehloohong oa kalafo e tiileng ea tharollo ea li-castings tsa tšepe e sa hloekang ke ho qhaqha li-carbides kapa mekhahlelo e meng e oeleng ka tharollo e tiileng ho fumana sebopeho sa mokhahlelo o le mong oa supersaturated. Lisebelisoa tsa tšepe e sa hloekang ea austenitic, tšepe ea austenitic manganese le litšepe tse thata tse sa tsitsang tsa pula hangata e lokela ho ba tharollo e tiileng.
Martensitic pula e thatafatsa tšepe e sa hloekang hangata e na le khabone ka tlase ho 0.1%. Matlafatsa ka ho eketsa likarolo tse thata (koporo, aluminium, titanium le aluminium, joalo-joalo) ho etsa hore ho be le ho hloka matla. Litaba tsa chromium ka kakaretso li phahame ho feta 17%, 'me palo e loketseng ea nickel e eketsoa ho ntlafatsa ho hanyetsa ho bola.
Pula e thata e thatafatsang tšepe e sa hloekang ke mofuta oa tšepe ea alloy e nang le khabone e seng holimo ho 0.03% ho netefatsa ho tiea, ho hanyetsa kutu, ho cheseha le ho sebetsa ha matrix a martensite, le 12% chromium ho netefatsa ho hanyetsa ho bola. Ntle le moo, cobalt ea alloy element e eketsoa ho ntlafatsa ts'ebetso ea mocheso oa tšepe.
Semi-austenitic pula e thatafatsa tšepe e sa hloekang, ke hore, pula ea nakoana e thatafatsang tšepe e sa hloekang, e nang le chromium e seng ka tlase ho 12%. E na le khabone e tlase, 'me aluminium ke eona ntho ea mantlha e thatafatsang pula. Mofuta ona oa pula o thatafatsang tšepe e sa hloekang o na le ts'ebetso e ntlafetseng ho feta pula ea martensitic e thatafatsang tšepe e sa hloekang.
Austenitic precipitation e thatafatsa tšepe e sa hloekang ke tšepe e sa hloekang e nang le sebopeho se tsitsitseng sa austenite libakeng tse tingoeng le tsa botsofali. Lintho tsa eona tsa nickel le manganese li holimo, 'me litaba tsa chromium li phahame ho feta 13% ho netefatsa hore ho na le ho hanyetsa ha kutu le ho hanyetsa oxidation. Ka nako e ts'oanang, pula e thata e thatafatsang tšepe e sa hloekang hangata e eketsa titanium, aluminium, vanadium kapa phosphorus e le lintho tse thatafatsang pula, 'me e eketsa palo e nyane ea boron, vanadium, nitrogen le lintho tse ling ho fumana thepa e phethahetseng.
