Hau long skelim pefomens
Tasol, ki komponen bilong wanpela stiel i no inap hat em i save stap longpela taim long bikpela tempereja, we ol i ken skelim long kain kain bilong ol narapela narapela rot. Wanpela rot bilong skelim wok bilong wanpela ain long bikpela tempereja em long skelim UTS na YS long ol tempereja i go antap, planti taim moa long 1200F} Planti hat resisten stiel i ken holim wanpela UTS bilong30-50} Planti hat resistant stiel i ken holim wanpela UTS bilong30-50} Planti hat resisten stiel i ken holim wanpela UTS bilong30-50} Planti hat resistant stiel i ken holim wanpela UTS bilong30-50}P 30ksi{6} tipikol, ol aloi we i gat inap kromium na nikel konten i save mekim gutpela wok tru long dispela kategori bilong elevted tempereja tensil na strong bilong givim, wantaim HL, HP, HU, na HK. Ol aloi long dispela kategori i save gat wanpela ful austenitik straksa bilong . pe bilong en i dia tumas.
Narapela rot we ol i skelim wok bilong stiel i no inap hat em long sait bilong strong bilong en i save kamap nogut na i gat hevi long en, em strong bilong en i save kamap long ol 'heat resistant stiel castings'. Long ol lain husat i no save long en, ol i save mekim ol samting i kamap long ol kasting we i stap aninit long bikpela hat bilong ol, planti bilong ol i no inap long mekim ol samting i kamap insait long bikpela hat. digri, we long en, i mekim sevis laip bilong kasting. we krip i kamap bikpela hevi tru em long ol selekted kes we em i kamapim kasting difomesen na em inap iven kamapim ol bruk bikos long strong bilong kasting i stap long kompromis olsem em i bruk aninit long ol samting ol i makim long wanpela eleveted tempereja tensile tes.}

Seleksen bilong aloi
Creep can be accounted for in casting design and in alloy selection, an engineer can select a casting design that will allow the casting to continue to perform for an extended period in the event of creep and may also select an alloy that is more resistant to creep. In terms of alloy selection, an engineer should select an alloy that slows the process of plastic deformation and has a high rupture stress, prioritizing one or the other based upon the aplikesen. Long sait bilong difomesen kontrol, nambawan bet em i save go wantaim wanpela aloi we i gat 30% nikel na 15% krom long kisim wanpela ful austenitis straksa, HT, HU, na HP em ol gutpela eksampel tu long dispela er erora{4} Sampela ain-kromium-nikel aloi i save mekim gutpela wok.
Taim em i kam long hevi bilong 'rupture', kontrolim kabon konten long stap insait long 0.3-0.7% mak bai stap olsem nambawan bikpela veriebol. Long 0.3-0.7% kabon rein, metal bai i stap strong moa long ol hevi bilong bruk winim ol lain i gat 0{{4}% na aninit long. Narapela austenitis straksa i stap tu. i moa gud se 22%+) mo wan kromium konten we i moa long 15% oli ki, HK, HN, mo HP oli ol kwaliti eksampol. Sam long ol aloi we oli no save ron strong tumas bae i gat sam konten blong ol spesel aloying element olsem tungsten o niobium, nomata we kabon konten i stap olsem wan impak we i gat moa impak long kontrol.

Noken kisim oksidesen
Narapela ki long steinles stiel em long resistens long oksidesen long bikpela tempereja. Long dispela as, wanpela steinles stiel i no inap hat long hat i mas gat minimam bilong 12% kromium bilong sakim ain oksait fomesen long bikpela tempereja{{2} Moa oksidesen resistens i ken kisim long rot bilong wanpela bikpela kromium na nikel konten.

Bel les
Sapos wanpela kasting i stap aninit long thermal baisikol o sek, dispela tu i mas tingim taim em i kam long aloi seleksen bilong wanpela hat resistant stiel. I no gat gutpela rot bilong skelim thermal les long wanpela kasting, i gat ol tes bilong les bilong hat, tasol ol i no karim tru i go long rilitis.}

Olsem wanem long sakim kaburisasen
Kabureisasen resistens em i narapela tingting long mekim, moa yet long ol kasting we bai stap insait long wanpela aplikesen olsem komesel hat tritmen. Haia nikel na kromium konten i mekim bikpela hap i apim strong bilong ain long kabon penetresen i go insait long pes bilong kasting. Silikon i mekim wanpela bikpela wok long strong bilong karbureisin resistens tu, liklik inkris long silikon inap mekim silikon i ken mekim silikon inap long daunim kabon penet tu. 2% silikon i save kamap long ol kasting we i bilong daunim karburisasen{{3} Ol narapela aloi element i bin go insait long ol steinles stiel long sakim karburisesen maski ol i no yusim planti na wok bilong ol i stap yet olsem tok pait.
Ol narapela samting ol i mas tingim
Long ol kes i no planti, ol i mas tingim ol samting bilong wanpela hai salfa envairomen we bai kamapim oksidesen long ol stiel kasting. hai nikel konten hat resisten aloi i save kisim bagarap tru long korosen long wanpela hai salfa envairomen bikos long ful austenitis straksa bilong ol, olsem na ol aloi i gat olgeta feritik i save stap olsem wanpela gutpela seleksen{1}}}.
