Nws qhov kev tiv thaiv corrosion txaus nyob rau hauv ib puag ncig me ntsis hnyav.
316 stainless hlau zoo tshaj plaws hauv cov khoom siv hauv dej hiav txwv, tshuaj lom neeg, thiab tshuaj. Qhov muaj 2–3% molybdenum yog qhov tseem ceeb thaum xaiv cov hlau stainless zoo tshaj plaws rau cov chaw nyob hauv dej hiav txwv lossis cov kab ua haujlwm hauv kev lag luam uas raug rau chlorides, ua tau zoo dua 304 hauv kev pabcuam dej ntsev thiab cov kua qaub.
321 stainless hlau dominates thermal thiab aerospace daim ntawv thov, jet engine exhaust manifolds, thiab petrochemical cua sov, nrog rau kev tiv thaiv zoo dua rau scaling thiab lub zog khaws cia txog li 900 ° C. Nws cov titanium ntxiv ua kom ntseeg tau tias muaj kev ntseeg siab nyob rau hauv rov ua dua thermal cycling, txo qis kev pheej hmoo ntawm carbide precipitation tom qab welding.
