Stainless hlau yog lub ntsiab lus ntawm stainless acid-resistant steel. Cov hlau uas tiv taus tsis muaj zog corrosive media xws li cua, chav, thiab dej los yog stainless yog hu ua stainless hlau; Thaum cov hlau uas tiv taus cov tshuaj tiv thaiv corrosion media (tshuaj corrosion xws li acid, alkali, ntsev, thiab lwm yam) Cov hlau yog hu ua acid-resistant steel.
Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm ob, lawv cov corrosion kuj sib txawv. Ordinary stainless hlau feem ntau tsis tiv taus corrosion los ntawm tshuaj lom neeg, thaum acid-resistant steel feem ntau stainless. Lo lus "stainless steel" tsis tsuas yog xa mus rau ib hom stainless hlau, tab sis hais txog ntau tshaj li ib puas industrial stainless hlau, txhua yam yog tsim los kom muaj kev ua tau zoo hauv nws cov ntawv thov tshwj xeeb. Tus yuam sij rau kev ua tiav yog ua ntej nkag siab txog daim ntawv thov thiab tom qab ntawd txiav txim siab qib steel raug. Muaj feem ntau tsuas yog rau hom hlau cuam tshuam rau kev tsim kho vaj tse. Lawv txhua tus muaj 17 mus rau 22% chromium, thiab cov hlau zoo dua kuj muaj npib tsib xee. Ntxiv molybdenum tuaj yeem txhim kho cov huab cua tiv thaiv corrosion, tshwj xeeb tshaj yog cov tshuaj tiv thaiv corrosion ntawm chloride-muaj cua.
Feem ntau hais lus, lub hardness ntawm stainless hlau yog siab dua li ntawm aluminium alloy, thiab tus nqi ntawm stainless hlau yog siab dua li ntawm aluminium alloy.
