304 316L 2205 S31803 saxan bir ah oo aan lahayn
Bandhiga alaabta:
Iska caabbinta daxalka ee birta aan kala go 'lahayn waxay inta badan ku xiran tahay halabuurka daawaha (Cr, Ni, Ti, Si, Al, Mn, iwm.) iyo qaabdhismeedkeeda gudaha.
Marka loo eego habka wax soo saarka ee duubista kulul iyo qabowga laba nooc, marka loo eego sifooyinka unugyada nooca birta waxaa loo qaybiyaa 5 qaybood: nooca austenite, nooca austenite-ferrite, nooca ferrite, nooca martensite, nooca adkeynta roobabka.
Dusha saxan bir ah oo siman, waxay leedahay caag sare, adkaanta iyo xoogga farsamada, caabbinta aashitada, gaaska alkaline, xal iyo daxalka kale ee warbaahinta.Waa bir alwaax ah oo aan si fudud u miridhkumin.

SA588 SA387 Alloy Steel Plate
Bandhiga alaabta:
Marka loo eego nuxurka walxaha alloy waxa loo qaybiyaa:
birta daawaha hoose (wadarta guud ee walxaha alloy waxay ka yar yihiin 5%),
Bir daawaha dhexdhexaadka ah (5% -10% wadarta walxaha alloy)
Biraha daawaha sare (wadarta walxaha daawaha ayaa ka sarreeya 10%).
Sida uu qabo curiyaha aluminiumka ee ka kooban:
Birta Chromium (Cr-Fe-C)
Birta Chromium-nickel (Cr-Ni-Fe-C)
Birta Manganese (Mn-Fe-C)
Birta Silikon-manganese (Si-Mn-Fe-C)

Saxan-iska-caabbinta xidho, saxanka u adkaysta cimilada
Bandhiga alaabta:
Saxanka birta u adkaysta waxa uu ka kooban yahay laba qaybood: saxan birta kaarboon-yar iyo lakabka alwaax u adkaysta.Lakabka alwaax u adkaysta guud ahaan waa 1/3 ~ 1/2 ee dhumucda guud.Marka la shaqeynayo, matrixku wuxuu bixiyaa waxqabadka dhamaystiran sida xoogga, adkaanta iyo caagagga, iyo lakabka xirashada u adkeysiga u adkaysta waxay bixisaa caabbinta xirashada si loo buuxiyo shuruudaha shuruudaha shaqada ee cayiman.
Lakabka alwaax u adkaysta inta badan waa chromium alloy, iyo manganese, molybdenum, niobium, nikkel iyo qaybaha kale ee daawaha ayaa sidoo kale lagu daray.Carbiid-ka ku jira unugyada metallographic waxaa loo qaybiyaa qaabka fiber-ka, iyo jihada fiberku waa mid siman oo dusha sare ah.Microhardness-ka carbide wuxuu gaari karaa in ka badan HV1700-2000, iyo engegnaanta dusha sare waxay gaari kartaa HRC 58-62.Aloy carbide waxay leedahay xasillooni xoog leh oo heerkul sare ah, ilaali qallafsanaanta sare, laakiin sidoo kale waxay leedahay sifooyin antioxidant wanaagsan, gudaha 500 ℃ isticmaalka gebi ahaanba caadiga ah.

S235JR S275JR S355JR saxan kaarboon ah
Bandhiga alaabta:
Taarikada birta waxay u qaybsantaa taariko kulul iyo qabow.
Sida laga soo xigtay noocyada birta, waxaa jira birta caadiga ah, birta tayada sare leh, birta daawaha, birta guga, birta aan lahayn, birta qalabka, birta kulaylka u adkeysata, birta sita, birta silikoon iyo birta saafiga ah ee warshadaha.
Birta kaarboonka ee tayada sare leh waxa loo qaybin karaa saddex qaybood iyadoo loo eegayo kaarboonka kala duwan: birta kaarboon yar (C 0.25%), birta kaarboon dhexdhexaad ah (C waa 0.25-0.6%) iyo birta kaarboon sare (C & gt; 0.6%).
Qalabka kaarboonka ee tayada sare leh ayaa loo qaybiyaa manganese caadiga ah (0.25% -0.8%) iyo manganese sare (0.70% -1.20%), kan dambe wuxuu leeyahay sifooyin farsamo oo wanaagsan iyo sifooyin wax-qabad.
