Cov kev txiav txim siab tseem ceeb thaum xaiv cov khoom sib npaug:
Corrosion Kuj: Monel 400 txawj ua txuj ci hauvMarine ib puag ncigthiabCov Ntawv Thov Dej Hiav Txwv, uas yog ib qho tseem ceeb thaum xaiv nws sib npaug. ThaumHastelloy c -276thiabInconel 625Kev muab cov tshuaj tiv thaiv zoo dua rau cov tshuaj dav dav,Monel 400yog tus nqi ntau rau kev siv dej hiav txwv.
Kub tiv thaiv: Inconel 625yog muaj haum rauKev Siv Hluav Taws Xob Kub, raws li nws tuaj yeem tiv taus kub txog li1, {000 degree (1,800 degree f), whereasMonel 400yog zoo dua haum rauKev ntsuas qhov hluav taws xob hnyav.
Lub zog: Inconel 625thiabHastelloy c -276kev muab lub zog siab dua thiab oxidation tiv taus, ua rau lawv zoo tagnrho rau cov kev siv siab, kom siab siv kub sib piv tau piv rauMonel 400.
Thaum xaiv cov khoom sib npaug:
Yognqi zog-ua hauj lwmnyob rau hauv cov tub rog lossis dej hiav txwv ib puag ncig yog qhov tseem ceeb,Monel 400feem ntau yog qhov kev xaiv zoo tshaj plaws.
RauCov Khoom Siv Uas Huab KujthiabQhov Kub SiabCov xwm txheej, cov ntaub ntawv zoo liHastelloy c -276lossisInconel 625tuaj yeem muab kev ua tau zoo dua.
Stainless hlau 316tuaj yeem yog lwm txoj kev xaiv thaumdej hiav txwv corrosionkev tawm tsam yog yuav tsum tau tab sis ntawm tus nqi qis dua, txawm hais tias nws tsis muaj lub zog lossis kev tawm tsam nyob rau hauv cov xwm txheej huabMonel 400.
