Sezvatinoziva tese, zvigadziriso zvesimbi isina tsvina zvakaiswa mu austenitic Stainless simbi, ferritic Stainless simbi uye martensitic Stainless simbi.
Magiredhi emabhaudhi esimbi asina tsvina akakamurwa kuita 45, 50, 60, 70, uye 80. Zvishandiso zvakakamurwa zvakanyanya kuita austenite A1, A2, A4, martensite uye ferrite C1, C2, uye C4. Iyo nzira yekutaura yakaita seA2-70, isati yasvika uye mushure "--" zvichiteerana inoratidza iyo bhaudhi zvinhu uye simba nhanho.
1.Ferritic Stainless Steel
(15% -18% Chromium) - Ferritic Stainless simbi ine simba re 65,000 - 87,000 PSI. Kunyangwe ichiri kushingirira mukuora, haikurudzirwe kuti ishandiswe munzvimbo dzinogona kuita ngura, uye inokodzera masiruuru esimbi asina kusimba zvishoma uye kudzivirira kupisa, uye simba rakawanda rinodiwa. Ichi chinyorwa hachigone kurapwa kupisa. Nekuda kwemaitiro ekuumba, ndeye magineti uye haina kukodzera kushambadzira. Ferritic mamakisi anosanganisira: 430 uye 430F.
2.Martensitic Stainless Steel
(12% -18% Chromium) - Martensitic simbi isina tsvina inonzi isimbi yemagineti. Inogona kuve inopisa kurapwa kuti iwedzere kuoma kwayo uye haikurudzirwe kune welding. Stainless simbi dzerudzi urwu dzinosanganisira: 410, 416, 420, uye 431. Vane simba rekusimudzira pakati pe180,000 ne250,000 PSI.
Type 410 uye Type 416 inogona kusimbiswa nekupisa kurapwa, nekuoma kwe35-45HRC uye yakanaka machinability. Iwo anodzivirira kupisa uye anodzivirira corrosion-resistain stainless simbi screws nokuda kwezvinangwa zvakawanda. Type 416 ine sarufa yakakwira zvishoma uye iri nyore kucheka simbi isina tsvina. Type 420, ine sulfur yemukati yeR0.15%, yakavandudza ma mechanical properties uye inogona kusimbiswa nekupisa kurapwa. Iyo yakanyanya kuoma kukosha ndeye 53-58HRC. Inoshandiswa kune Stainless simbi screws inoda simba repamusoro.
3.Austenitic Stainless Steel
(15% -20% chromium, 5% -19% nickel) - Austenitic Stainless steels ine yakanyanya kusimba yekudzivirira kwemhando nhatu. Iri kirasi yesimbi isina tsvina inosanganisira mamakisi anotevera: 302, 303, 304, 304L, 316, 321, 347, uye 348. Vanewo simba rekugadzirisa pakati pe80,000 - 150,000 PSI. Ingave iri corrosion resistance, kana kuti ma mechanical properties akafanana.
Type 302 inoshandiswa kune akagadzirwa screws uye ega-tapping mabhaudhi.
Type 303 Kuti uvandudze kuita kwekucheka, chidimbu chesarufa chinowedzerwa kune Type 303 simbi isina tsvina, iyo inoshandiswa kugadzira nzungu kubva kubhawa stock.
Type 304 inokodzera kugadzirisa simbi isina simbi screws neinopisa musoro maitiro, senge mabhaudhi akareba uye mabhoti mahombe edhayamita, anogona kudarika chiyero chekutonhora kwemusoro.
Type 305 inokodzera kugadzirisa simbi isina simbi screws nekutonhora musoro maitiro, senge inotonhora yakagadzirwa nzungu uye hexagonal mabhaudhi.
316 uye 317 mhando, iwo ese ane alloying element Mo, saka iwo tembiricha yakanyanya simba uye corrosion resistance yakakwira kupfuura 18-8 stainless steel.
Type 321 uye Type 347, Type 321 ine Ti, yakagadzikana alloying chinhu, uye Type 347 ine Nb, inovandudza intergranular corrosion kuramba kwezvinhu. Yakakodzera simbi isina simbi yakajairwa zvikamu zvisina kuvharwa mushure mekunama kana zviri kushanda pa420-1013 °C.
