Hunhu: Inogona kumira yakadzokororwa kudziyisa pazasi 980 ℃, ine yakakwirira tembiricha simba, oxidation kuramba uye carburizing kuramba.
Chishandiso: midziyo yevira, inogona kushandiswa kugadzira simbi inopisa, Yayo yakakwira chromium uye nickel yemukati inovimbisa kunaka kwekusagadzikana uye oxidation kuramba.
Kuenzaniswa ne austenitic 304 alloy, ine zvishoma kusimba pakamuri tembiricha. Muhupenyu chaihwo, inogona kudzokororwa kupisa pa980 ° C kuchengetedza basa rakajairwa.310s: (0Cr25Ni20) ndiro yesimbi isina tsvina.
2.310s: (OCr25Ni20) ndiro yesimbi isina tsvina
Hunhu: Yakakwira chromium-nickel austenitic Stainless simbi ine yakanaka yakakwira tembiricha michina zvivakwa uye yakanaka corrosion kuramba mune oxidizing media. Inokodzera kugadzirwa kweakasiyana siyana echoto, tembiricha yepamusoro 1200 ℃, kuenderera kwekushandisa tembiricha 1150 ℃.
Kushandisa: choto zvinhu, motokari yekuchenesa mudziyo mudziyo.
310S Stainless simbi isimbi inodzivirira kana austenitic Stainless steel alloy inoshandiswa munzvimbo dzakasiyana siyana dzekupisa uye dzinoparadza. Iyo isarudzo yakanakisa yezvishandiso mune petrochemical, makemikari, uye kupisa-kupisa maindasitiri, pamwe nezvikamu zvechoto uye zvimwe zvinopisa-tembiricha zvikumbiro. Iyo 310S Stainless simbi ndiro ifurati, shizha rakatetepa rakagadzirwa kubva kune iyi chaiyo alloy.
3.253MA (S30815) ndiro yesimbi isina tsvina
Hunhu: 253MA isimbi isingadziviriri Austenitic stainless simbi yakagadzirirwa maapplication inoda simba rekukwira uye yakanaka corrosion resistance. Iyo tembiricha yekushanda kwayo ndeye 850-1100 ℃.
253MA imhando chaiyo yesimbi isina simbi alloy yakagadzirirwa kushandiswa kwepamusoro-tembiricha. Iyo inopa yakanakisa kuramba kune oxidation, sulfidation, uye carburization pane yakakwirira tembiricha. Izvi zvinoita kuti ive yakakodzera kushandiswa mumaindasitiri akasiyana, kusanganisira ayo anosanganisira kupisa uye ngura, senge petrochemical, kugadzirwa kwemagetsi, uye maindasitiri echoto zvikamu.253MA mashiti zvitete, zvipenga zvezvinhu zvakagadzirwa kubva kune alloy iyi. Izvo zvinoshandiswa mumhando dzakasiyana-siyana apo kusanganiswa kwepamusoro-kupisa kupikisa uye kusagadzikana kwehutu kunokosha. Iwo mapepa anogona kutemwa uye kuumbwa kuita maumbirwo akasiyana kuti asangane nezvinodiwa zvepurojekiti.

253MA Plate Corrosion kuramba uye nzvimbo huru yekushandisa:
1.Corrosion Resistance: 253MA inozvirumbidza yakanakisa oxidation kuramba, yakakwirira-tembiricha corrosion resistance, uye inoshamisa yakakwirira-tembiricha mechanical simba. Inonyanya kushanda mukati mekupisa kwe850 kusvika 1100 ° C.
2.Temperature Range: Kuti uite zvakakwana, 253MA inonyanya kukodzera kushandiswa mukati mekushisa kwe850 kusvika ku1100 ° C. Pane tembiricha dziri pakati pe600 ne850°C, shanduko yezvimiro inoitika, zvichikonzera kuderera kwesimba kusimba patembiricha yekamuri.
3.Mechanical Strength: Iyi alloy inopfuura simbi isina tsvina, yakadai se304 uye 310S, maererano nekusimba kwekusimba kwenguva pfupi pakupisa kwakasiyana-siyana nepamusoro pe20%.
4.Chemical Maumbirwo: 253MA inoratidzira yakaenzana kemikari yakagadzirwa iyo inopa iyo inoshamisa kushanda mutembiricha ye850-1100 ° C. Inotaridza kukwirira kwakanyanya kweoxidation, inoshingirira tembiricha inosvika 1150°C. Iyo zvakare inopa yakakwirira creep resistance uye creep fracture simba.
5.Corrosion Resistance: Pamusoro pekugona kwayo kwepamusoro-tembiricha, 253MA inoratidza kupikisa kwakanyanya kune-yepamusoro-tembiricha corrosion uye brashi corrosion munzvimbo dzakawanda dzine gasi.
6.Strength: Iine simba regoho repamusoro uye simba rekusimba pakupisa kwakakwirira.
7.Formability uye Weldability: 253MA inozivikanwa nokuda kwekunaka kwayo, weldability, uye machinability.
