ASTM A312 UNS S31254 stainless hlau tubingtus neeg muag khoom
ASTM A312 UNS S31254 stainless hlau seamless txias- cov tubing tiav yog suav tias yog qib austenitic, khav peb lub zog ntawm 300 series stainless hlau. Nws tuav lub zog siab txawm tias nyob rau hauv cov xwm txheej tsis ruaj khov thiab feem ntau yog siv hauv boiler thiab tshav kub exchanger daim ntaub ntawv.
SMO254 tubing kuj zoo tiv thaiv pitting, crevice corrosion, thiab chloride stress corrosion cracking. Vim qhov sib ntxiv ntawm cov kab ntau ntawm
molybdenum, nws tseem hu ua Moly 6. 254 SMO tubing cov chaw muag khoom pom zoo cov tubing no rau lawv lub peev xwm ua haujlwm ntawm qhov kub thiab txias thiab lawv lub zog tshwj xeeb thiab kev ncaj ncees, ua rau lawv tsim nyog rau cov ntawv thov xws li kev ua tshuaj lom neeg, dej hiav txwv tuav, thiab cov roj thiab roj av.
