ASTM A269 Hom 347 Stainless Hlau Tube

ASTM A269 Hom 347 Stainless Hlau Tubeyog stabilized Nb-muaj alloy. UNS S34700 muaj kev tiv thaiv zoo corrosion thiab me ntsis corrosion kuj zoo dua li 321 (UNS S32100) nyob rau hauv muaj zog oxidizing tej yam kev mob. Nws kuj tseem tiv taus corrosion hauv ntau cov organic thiab inorganic acids xws li acetic, sulfuric thiab phosphoric acids. Nws muaj kev tiv thaiv zoo heev rau intergranular corrosion tom qab raug kub ntawm 800 - 1500 degree F (427 - 816 degree) qhov twg chromium carbides precipitate. Peb yog SS 347 tus neeg muag khoom nrog 15+ xyoo dhau los ntawm kev xa tawm, tiv tauj peb kom paub ntau ntxiv thiab nqe lus pub dawb!
