Simbi isingapisi inopisa inowanzo patsanurwa kuita mhando nhatu, 309S, 310S uye 253MA, simbi isingapisi inopisa inowanzo shandiswa mukugadzira mabhoyira, maturbine emhepo, maovheni emaindasitiri nendege, petrochemical nedzimwe nzvimbo dzemaindasitiri muzvikamu zvekushanda zvinopisa zvakanyanya.
1.309s: (OCr23Ni13) ndiro yesimbi isina ngura
Hunhu: Inogona kutsungirira kupisa kunodzokororwa pasi pe980 ℃, ine simba rekupisa kwakanyanya, kuramba oxidation uye kuramba carburizing.
Mashandisirwo: zvinhu zvechoto, zvinogona kushandiswa kugadzira zvikamu zvesimbi inopisa, huwandu hwayo hwakawanda hwechromium uye nickel hunovimbisa kuramba kwakanaka kwengura uye kuramba oxidation.
Kana ichienzaniswa ne austenitic 304 alloy, yakasimba zvishoma patembiricha yemumba. Muhupenyu chaihwo, inogona kudziiswa kakawanda pa980 ° C kuti irambe ichishanda zvakanaka. 310s: (0Cr25Ni20) ndiro yesimbi isina ngura.
2.310s: (OCr25Ni20) ndiro yesimbi isina ngura
Hunhu: Simbi isina ngura yakawanda ine chromium-nickel austenitic ine hunhu hwakanaka hwemakanika anodziya uye inodzivirira ngura zvakanaka mu oxidizing media. Yakakodzera kugadzirwa kwezvikamu zvakasiyana-siyana zvechoto, tembiricha yepamusoro ye1200 ℃, tembiricha yekushandiswa nguva dzose ye1150 ℃.
Kushandiswa: zvinhu zvechoto, zvinhu zvekuchenesa mota.
Simbi isingatsvi 310S isimbi isingatsvi ngura inoshandiswa munzvimbo dzakasiyana-siyana dzinopisa zvakanyanya uye dzinopisa. Isarudzo yakanaka kwazvo yekushandisa mumaindasitiri emafuta, makemikari, uye ekupisa, pamwe chete nemidziyo yemoto nezvimwe zvinoshandiswa pakupisa kwakanyanya. Ndiro yesimbi isingatsvi 310S ipepa rakati sandara, rakatetepa rakagadzirwa nesimbi iyi chaiyo.
3.253MA (S30815) ndiro yesimbi isina ngura
Hunhu: 253MA isimbi isina ngura yeAustenitic inodzivirira kupisa yakagadzirirwa kushandiswa inoda simba rakawanda uye inodzivirira ngura zvakanaka. Tembiricha yayo yekushanda ndeye 850-1100 ℃.
253MA imhando chaiyo yesimbi isina ngura yakagadzirirwa kushandiswa pakupisa kwakanyanya. Inodzivirira zvakanyanya kuoxidation, sulfidation, uye carburization pakupisa kwakakwira. Izvi zvinoita kuti ikodzere kushandiswa mumaindasitiri akasiyana-siyana, kusanganisira ayo ane chekuita nekupisa nengura, akadai se petrochemical, kugadzira magetsi, uye maindasitiri evira.Machira e253MA zvidimbu zvakatetepa, zvakati sandara zvakagadzirwa nechinhu ichi. Anoshandiswa mumabasa akasiyana-siyana apo musanganiswa wekudzivirira kupisa kwakanyanya uye kudzivirira ngura zvakakosha. Machira acho anogona kuchekwa uye kugadzirwa kuita maumbirwo akasiyana kuti aenderane nezvinodiwa zvepurojekiti.

253MA Plate Kudzivirira ngura uye nzvimbo huru yekushandisa:
1. Kuramba Kuora: 253MA ine simba rakanaka rekudzivirira kuoxidation, kuramba ngura pakupisa kwakanyanya, uye simba guru remakanika pakupisa kwakanyanya. Inoshanda zvakanyanya mukati mekupisa kuri pakati pe850 ne1100°C.
2. Kureba kwekupisa: Kuti ishande zvakanaka, 253MA ndiyo inonyanya kukodzera kushandiswa mukati mekupisa kuri pakati pe850 ne1100°C. Pakupisa kuri pakati pe600 ne850°C, shanduko dzemuumbi dzinoitika, zvichikonzera kudzikira kwekusimba kwekupisa pakupisa kwemumba.
3. Simba reMichina: Chiumbwa ichi chinodarika simbi dzisina ngura dzakajairwa, dzakadai se304 ne310S, kana tichitarisa simba rekudhonza kwenguva pfupi pakupisa kwakasiyana-siyana neanopfuura 20%.
4. Kuumbwa Kwemakemikari: 253MA ine makemikari akaenzana anoita kuti ishande zvakanaka pakupisa kwe850-1100°C. Inodzivirira zvakanyanya oxidation, inodzivirira kupisa kusvika 1150°C. Inopawo simba rekudzivirira kukambaira uye kukambaira.
5. Kuramba Kuora: Kuwedzera pakugona kwayo kupisa zvakanyanya, 253MA inoratidza kusimba kwakanaka pakuora kupisa kwakanyanya uye ngura yemabhurashi munzvimbo zhinji dzine gasi.
6.Simba: Ine simba guru rekugadzira uye simba rekusunga pakupisa kwakakwirira.
7. Kugona Kuumbwa Uye Kugona Kubatanidzwa: 253MA inozivikanwa nekugona kwayo kuumbwa zvakanaka, kugona kuumbwa, uye kugona kuumbwa zvakanaka.
