Kev siv thiab qhov zoo ntawm 321 stainless hlau yeeb nkab
Kev siv thiab qhov zoo ntawm 321 stainless hlau yeeb nkab
321 stainless hlau kav, vim lawv cov titanium stabilization kev kho mob, tiv thaiv carbide buildup thiab yog li muaj zoo heev tiv thaiv intergranular corrosion. Yog li ntawd, lawv tau nyiam nyob rau hauv siab - kub thiab corrosive ib puag ncig thiab yog qhov zoo tagnrho rau aerospace pa, kev ua tshuaj lom neeg thiab khoom noj khoom haus. Lawv kuj tuav cov weldability zoo heev, lub zog thiab kev ua haujlwm ntawm qhov kub txog li 900℃(1650℃F).
Dab tsi yog kev siv ntawm 321 stainless hlau?
Nws yog qhov zoo tagnrho rau kev tsim cov khoom siv hluav taws xob, cov hlab ntsha siab, thiab cov tank cia. Cov khoom siv thermal: boilers, heat exchangers, thiab lub cub tawg feem ntau yog ua los ntawm 321 stainless hlau vim nws zoo heev kub tsis kam thiab oxidation kuj. Nws kuj tseem pom muaj nyob rau hauv cov khoom siv kho cua sov ua haujlwm.
