ASTM-SA516Gr60Z35 simbi yeplate yekuona kukanganisa:
1. SA516Gr60 chiyero chepamusoro: American ASTM, ASME zviyero
2. SA516Gr60 ndeyakadzika tembiricha yekumanikidza mudziyo ine kabhoni simbi ndiro
3. Mushonga wemakemikari weSA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Mechanical properties yeSA516Gr60
SA516Gr60 tensile simba re70 zviuru zvemapaunzi/square inch, chinhu chikuru chiri mukati C Mn Si ps control inosarudza kuita kwayo.Zvimwe zvinotsvaga zvishoma.Asme Standard Kutsanangurwa kwekabhoni simbi mahwendefa epakati uye yakaderera tembiricha yekumanikidza midziyo.
5. Mamiriro ekutumira eSA516Gr60
SA516Gr60 simbi ndiro inowanzo kupihwa mu rolling state, simbi ndiro inogona zvakare kuve yakajairwa kana kudzoreredza kushushikana, kana normalizing pamwe nekushushikana kurongeka.
SA516Gr60 ukobvu> 40mm simbi ndiro inofanira kuva normalized.
Kunze kwekunge zvatsanangurwa neimwe nzira neanoda, ukobvu hwesimbi ndiro ≤1.5in, (40mm), kana paine notched kuomarara zvinodiwa, hunofanirwa kuve hwakajairwa.
6. SA516Gr60 inoshandiswa kugadzira imwe-layer coil welding container, multi-layer hot sleeve coil welding container, multi-layer dressing container uye mamwe maviri uye matatu marudzi emidziyo uye yakaderera-tembiricha yekumanikidza midziyo.Inoshandiswa zvakanyanya mu petroleum, indasitiri yemakemikari, chiteshi chemagetsi, boiler uye mamwe mabasa, anoshandiswa mukugadzira mareactors, zvinopisa kupisa, separators, spherical matangi, oiri negasi matangi, liquefied gasi matangi, boiler dhiramu, liquefied petroleum steam silinda, hydropower station. high-pressure water pombi, turbine volute uye zvimwe midziyo uye zvikamu..
7. 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.
8. Naizvozvo, chimiro chev1 chinonzi ferrite+pearlite;Chimiro chev2 ndeye ferrite + sorbite;Iyo microstructure yev3 ndeye ferrite + troostite.
9. Kana kutonhora kuri 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.
10. Shanduko yesimbi ye hypereutectoid yakafanana neyeye hypoeutectoid simbi, nemusiyano wekuti ferrite inonaya kutanga mune yekupedzisira uye cementite inonaya kutanga mune yekare.
Nguva yekutumira: Zvita-14-2022
