ALLOY 254 STAINLESS STEEL

Alloy 254 SMO yog qhov kawg siab heev, molybdenum thiab nitrogen alloyed super austenitic stainless hlau nrog cov ntsiab lus qis. Nws qhia tau zoo heev rau pitting, crevice corrosion stress cracking, thiab corrosion qaug zog uniform corrosion. Alloy 254 SMO muaj zog ntau dua li cov qib austenitic, nrog lub zog ze li ob npaug ntawm 300 series stainless hlau. Nws kuj yog tus cwj pwm los ntawm kev ua haujlwm siab ductility thiab cuam tshuam lub zog. Nrog rau cov qib siab ntawm chromium, molybdenum, thiab nitrogen, Alloy 254 SMO feem ntau siv nyob rau hauv qhov chaw muaj chloride siab, xws li dej brackish, seawater, pulp zeb bleach nroj tsuag, thiab lwm yam chloride txheej txheem kwj. Hauv qee daim ntawv thov nws tau pom tias yog tus nqi ntau dua rau cov nickel thiab titanium alloys siab.
