UNS S34709 - Siab -Carbon Niobium-Stabilized Austenitic Steel Rau Siab -Tsev Siab Kev Pabcuam

Txheej txheem cej luam

UNS S34709 yog lub siab -carbon, niobium-stabilized austenitic stainless hlau, tshwj xeeb tsim los rau siab - kub, siab - cov ntawv thov siab uas yuav tsum tau muaj qhov tshwj xeeb nkag siab thiab intergranular corrosion kuj. Raws li qhov siab -carbon variant ntawm UNS S34700, nws muaj cov ntsiab lus carbon ntawm 0.04-0.10% thiab niobium ntxiv (Nb + Ta: 8 × C ~ 1.10%), xa cov khoom siab tshaj -kub creep zog piv rau S34700. Nws khaws cia 17.00-19.00% chromium thiab 9.00-13.00% npib tsib xee rau corrosion kuj, tsis yog-magnetic, thiab muaj weldability zoo nrog preheating. Qib no yog siv dav hauv kev lag luam hluav taws xob, petrochemical, thiab aerospace kev lag luam rau cov hlab ntsha kub siab thiab cov khoom tseem ceeb, muaj peev xwm ua haujlwm txuas ntxiv mus txog 850 degree.

Core Zoo

Niobium stabilization tiv thaiv intergranular corrosion nyob rau hauv welds thiab siab -kev pab kub; cov ntsiab lus carbon siab txhim kho siab -kub creep zog thiab mechanical stability; oxidation kuj zoo heev ntawm qhov kub siab (txog 850℃kev pabcuam txuas ntxiv); tsis yog-magnetic; zoo weldability nrog preheating; superior siab -kub kev ua tau zoo piv rau UNS S34700; haum rau siab -kub, siab - kev siv siab.

Daim ntawv thov

Siab -kub, siab -siab boilers, chav turbines, petrochemical cracking khoom, nuclear fais fab nroj tsuag Cheebtsam, thiab aerospace cav qhov chaw yuav tsum tau tshwj xeeb creep zog thiab corrosion kuj.
