347/347H Stainless Hlau Phaj - Siab-Kev Ua Haujlwm Kub Kub-Resistant Alloy

General Properties

Alloy 347 (UNS S34700) yog columbium stabilized austenitic stainless hlau phaj nrog zoo dav corrosion kuj thiab me ntsis zoo kuj nyob rau hauv muaj zog oxidizing tej yam kev mob tshaj 321 (UNS S32100). Nws muaj kev tiv thaiv zoo heev rau intergranular corrosion tom qab raug kub hauv chromium carbide nag lossis daus ntawm 800 - 1500℃F (427 - 816 degree). Cov hlau muaj qhov zoo oxidation tsis kam thiab creep zog rau 1500℃F (816 degree). Nws kuj muaj qhov zoo ntawm qhov kub thiab txias toughness.
