FAQ
Q1: Qhov txawv ntawm C12200 thiab C11000 tooj liab yog dab tsi?
A: C12200 yog phosphorus deoxidized tooj liab (0.015-0.040% P). C11000 yog electrolytic tawv pitch tooj liab (siab purity, tsis muaj deoxidizer). C12200 yog weldable thiab brazeable; C11000 tuaj yeem raug kev txom nyem hydrogen embrittlement thaum welded. C12200 muaj hluav taws xob qis dua me ntsis (70-90% IACS vs 100% + rau C11000) tab sis cov khoom zoo sib xws.
Q2: Vim li cas phosphorus txo cov conductivity hauv C12200?
A: Phosphorus atoms nyob rau hauv cov kua nplaum tawg tawg electrons, txo cov hluav taws xob thiab thermal conductivity. C12200 conductivity ranges ntawm 70-90% IACS piv rau 100%+ rau cov tooj liab ntshiab. Txawm li cas los xij, kev lag luam tawm yog txhim kho weldability thiab siab dua softening kub.
Q3: C12200 puas tuaj yeem siv rau hauv kev siv dej hiav txwv?
A: Yog, nrog ceev faj. Lub rooj tiv thaiv corrosion saum toj no teev cov dej hiav txwv raws li qhov nruab nrab tsim nyog. Txawm li cas los xij, rau siab - dej hiav txwv ceev los yog ntev - lub sij hawm immersion, cupronickel alloys (C70600, C71500) feem ntau nyiam. C12200 feem ntau yog siv rau dej tshiab, kav dej, thiab HVAC.
Q4: Dab tsi yog qhov siab tshaj plaws ua haujlwm kub rau C12200?
A: Rau kev pabcuam txuas mus ntxiv, txog li 200℃(400℃F). Tshaj qhov kub no, lub zog txo qis sai. Lub sij hawm luv luv - raug rau qhov kub siab dua tuaj yeem ua tau raws li qib kev ntxhov siab. Rau cov ntawv thov kub dua, xav txog lwm yam tooj liab alloys lossis stainless hlau.
Q5: Yuav ua li cas rau vuam C12200 tooj liab raj?
A: C12200 yog weldable los ntawm gas shielded arc vuam (TIG) thiab oxy-acetylene vuam. Siv deoxidized muab tub lim (ERCu). Ntxuav lub raj kom huv si ua ntej vuam. Tsis xav tau preheating rau cov phab ntsa nyias. Cov ntsiab lus phosphorus tiv thaiv hydrogen embrittlement.
Q6: Dab tsi yog qhov kub ntawm annealing rau C12200?
A: 250-650℃(482-1202℃F). Qhov ntsuas kub npaum li cas nyob ntawm qhov ntsuas qhov xav tau ntawm annealing thiab ua haujlwm txias ua ntej. Qhov kub qis dua (250-400 degree) muab kev ntxhov siab. Qhov kub siab dua (500-650 degree) ua kom tiav tag nrho nrog recrystallization.
Q7: Puas yog C12200 haum rau kev pabcuam hauv av?
A: Yog. Cov seem tiv thaiv corrosion sau tseg tias C12200 tiv thaiv av corrosion thiab tuaj yeem siv hauv av. Txawm li cas los xij, cov av hauv cheeb tsam sib txawv. Hauv cov av txhoj puab heev, kev tiv thaiv ntxiv (wrapping lossis txheej) yuav raug pom zoo.
Q8: Qhov ntsuas machinability ntawm C12200 yog dab tsi?
A: 20% ntawm dawb txiav tooj dag. C12200 yog gummy thiab nyhav rau daim ntawv ntev. Cov cuab yeej ntse, cov kaum sab xis zoo, thiab cov dej txiav tsim nyog raug pom zoo. Rau kev machining dav, xav txog cov hlau lead txhuas.
Q9: Dab tsi ASTM specifications npog C12200 tshav kub exchanger raj?
