S460N/Z35 simbi ndiro normalizing, European mwero yakakwira simba ndiro, S460N, S460NL, S460N-Z35 simbi mbiri: S460N, S460NL, S460N-Z35 inopisa yakakungurutswa weldable yakanaka zviyo simbi pasi peyakajairwa / yakajairwa kutenderera mamiriro, giredhi S460 simbi ndiro ukobvu. kwete kupfuura 200mm.
S275 ye-non-alloy structural simbi yekushandiswa mwero : EN10025-3, nhamba: 1.8901 Zita resimbi rine zvikamu zvinotevera: Chiratidzo chetsamba S: simbi yakarongeka yakabatana nehupamhi isingasviki 16mm goho rekukosha kwesimba: zvishoma goho kukosha Mamiriro ekutumira: N inotsanangura kuti kukanganisa patembiricha isiri pasi pe -50 madhigirii inomiririrwa nebhii guru L.
S460N, S460NL, S460N-Z35 Dimensions, chimiro, uremu uye kutsauka kunobvumirwa.
Saizi, chimiro uye kutsauka kunobvumidzwa kwesimbi ndiro ichaenderana neiyo EN10025-1 mu2004.
S460N, S460NL, S460N-Z35 mamiriro ekutumira Simbi mahwendefa anowanzo kuendeswa mune yakajairika mamiriro kana kuburikidza neakajairika kukunguruka pasi pemamiriro akafanana.
S460N, S460NL, S460N-Z35 Chemical Composition yeS460N, S460NL, S460N-Z35 simbi Chemical composition (melting analysis) inofanira kuenderana netafura inotevera (%).
S460N, S460NL, S460N-Z35 kuumbwa kwemakemikari zvinodiwa: Nb+Ti+V≤0.26;Cr+Mo≤0.38 S460N Melting Analysis Carbon Equivalent (CEV).
S460N, S460NL, S460N-Z35 Mechanical properties The mechanical properties uye maitiro ekugadzirisa eS460N, S460NL, S460N-Z35 achasangana nezvinodiwa zvetafura inotevera: Mechanical properties yeS460N (yakakodzera transverse).
S460N, S460NL, S460N-Z35 simba rekuita mune yakajairika mamiriro.
Mushure mekuvhara uye kujaira, iyo kabhoni simbi inogona kuwana yakaenzana kana padyo yakaenzana chimiro, uye mushure mekudzima, inogona kuwana isiri-yakaenzana chimiro.Naizvozvo, kana uchidzidza chimiro mushure mekupisa kupisa, kwete chete simbi kabhoni chikamu diagiramu asiwo isothermal shanduko curve (C curve) yesimbi inofanirwa kurehwa.
Iyo iron carbon phase diagram inogona kuratidza iyo crystallization process yealloy pakunonoka kutonhora, chimiro pakamuri tembiricha uye huwandu hunoenderana hwezvikamu, uye C curve inogona kuratidza chimiro chesimbi ine imwe kuumbwa pasi pemamiriro akasiyana ekutonhora.C curve inokodzera isothermal kutonhora mamiriro;Iyo CCT curve (austenitic inoramba ichitonhora curve) inoshanda kune inoenderera kutonhora mamiriro.Kusvika kumwero wakati, iyo C curve inogona zvakare kushandiswa kufungidzira shanduko ye microstructure panguva yekuenderera kutonhora.
Apo austenite inotonhorera zvishoma nezvishoma (yakaenzana nechoto kutonhora, sezvinoratidzwa mumufananidzo 2 V1), zvigadzirwa zvekushandura zviri pedyo nekugadzirisa maitiro, iyo pearlite uye ferrite.Nekuwedzera kwekutonhora kwekutonhora, ndiko kuti, kana V3> V2> V1, iyo undercooling ye austenite zvishoma nezvishoma inowedzera, uye huwandu hweferrite inonaya inova shoma uye shoma, nepo huwandu hwepearlite hunowedzera zvishoma nezvishoma, uye chimiro chinova chakanakisa.Panguva ino, shoma shoma yeferrite inonaya inonyanya kugoverwa pamuganhu wezviyo.
Naizvozvo, chimiro chev1 ndeye ferrite + pearlite;Chimiro chev2 ndeye ferrite + sorbite;Iyo microstructure yev3 ndeye ferrite + troostite.
Kana iyo inotonhorera iri v4, shoma shoma ye network ferrite uye troostite (dzimwe nguva shoma shoma yebainite inogona kuonekwa) inonaya, uye austenite inonyanya kuchinjwa kuva martensite uye troostite;Kana iyo yekutonhodza chiyero v5 ichipfuura yakakosha kutonhora mwero, simbi inoshandurwa zvachose kuita martensite.
Shanduko yesimbi ye hypereutectoid yakafanana neye hypoeutectoid simbi, nemusiyano wekuti ferrite inonaya kutanga mune yekupedzisira uye simenti inonaya kutanga mune yekutanga.
