347H - Siab-Carbon Niobium-Stabilized Austenitic Steel: Siab-Tub Siab Kev Pabcuam Alloy

Txheej txheem cej luam

347H yog lub siab -carbon, niobium-stabilized austenitic stainless hlau, tshwj xeeb yog tsim los rau siab - kub, siab - cov ntawv thov siab uas yuav tsum tau tshwj xeeb creep zog thiab intergranular corrosion kuj. Raws li qhov siab -carbon variant ntawm 347, 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 347. Nws khaws cia 17.19% thiab 18.000 9.00-13.00% npib tsib xee rau corrosion kuj, yog non-magnetic, thiab muaj weldability zoo nrog preheating. Cov qib no tau siv dav hauv kev siv hluav taws xob, petrochemical, thiab kev lag luam aerospace rau cov hlab ntsha kub siab thiab cov khoom tseem ceeb.

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; oxidation zoo heev (txog 850℃kev pabcuam txuas ntxiv); tsis yog-magnetic; zoo weldability nrog preheating; superior siab -kub kev ua tau zoo piv rau 347.

Daim ntawv thov

Siab - kub, siab - siab boilers, chav turbines, petrochemical cracking khoom, nuclear fais fab nroj tsuag Cheebtsam, thiab aerospace engine qhov chaw.
