Inconel 718 VS Inconel 625 Pipe: Uas Zoo dua?
Ob leeg Inconel 718 thiab 625 muaj lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab tsis muaj qhov sib txawv "zoo dua lossis phem dua". Inconel 625 yog qhov tsim nyog rau cov cheeb tsam uas muaj corrosive heev (xws li kev ua dej hiav txwv thiab tshuaj lom neeg) thiab muaj kev sib txuas zoo dua. Inconel 718 yog qhov tsim nyog rau cov ntawv thov uas xav tau lub zog siab tshaj plaws thiab ua haujlwm rau siab - qhov kub thiab txias.
Dab tsi yog qib Inconel 625 yeeb nkab?
Feem ntau, qhov txias txias no ua haujlwm Inconel 625 seamless yeeb nkab yog muab rau hauv ob yam xwm txheej: Qib 1 thiab Qib 2. ASTM B444 UNS N06625 Qib 1 yeeb nkab yog nkag rau hauv qhov mob annealed, thaum Qib 2 yeeb nkab tau muab rau hauv cov tshuaj -annealed mob.
Inconel 718 Pipe vs Inconel 625 Pipe: Cov ntsiab lus txhais
Inconel 718 yeeb nkab yog dab tsi?
Inconel 718 tubing yog nag lossis daus -nickel hardening-chromium superalloy. Nws muaj ntau npaum li cas ntawm niobium, molybdenum, thiab txhuas. Cov ntsiab lus no ua rau cov hlau mus rau lub hnub nyoog hardening.
Cov khoom no nthuav tawm cov txiaj ntsig zoo heev thiab lub zog tensile, thiab tuav nws cov qauv kev ncaj ncees txawm tias kub txog li 700 degree.
