Stainless hlau
Raws li lub ntsiab lus ntawm GB / T20878-2007, cov yam ntxwv tseem ceeb ntawm stainless hlau, corrosion kuj, thiab chromium cov ntsiab lus tsawg kawg yog 10.5%, cov ntsiab lus carbon ntawm qhov siab tshaj plaws yog tsis ntau tshaj 1.2%.
Stainless hlau (Stainless hlau) yog luv rau stainless acid-resistant steel, cua, chav, dej thiab lwm yam tsis muaj zog corrosion nruab nrab los yog stainless hlau;Thiab cov tshuaj corrosion resistant nruab nrab (acid, alkali, ntsev thiab lwm yam tshuaj etching) corrosion ntawm steel hu ua acid resistant steel.
Vim hais tias ntawm qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg ntawm ob thiab lawv cov corrosion kuj sib txawv, zoo tib yam stainless hlau feem ntau tsis resistant rau corrosion ntawm tshuaj lom neeg, thiab acid-resistant steel feem ntau tsis muaj xeb.Lo lus "stainless steel" tsis tsuas yog xa mus rau ib hom stainless hlau, tab sis txhais tau tias ntau tshaj li ib puas hom kev lag luam stainless hlau, kev txhim kho ntawm txhua stainless hlau muaj kev ua tau zoo hauv nws cov ntawv thov tshwj xeeb.Tus yuam sij rau kev vam meej yog thawj zaug kom paub txog lub hom phiaj, thiab tom qab ntawd txiav txim siab qhov zoo ntawm cov hlau.Feem ntau tsuas yog rau hom hlau uas muaj feem xyuam rau daim ntawv thov kev tsim kho vaj tsev.Lawv tag nrho muaj 17 mus rau 22 feem pua chromium, thiab cov hlau zoo dua kuj muaj cov npib tsib xee.Qhov sib ntxiv ntawm molybdenum tuaj yeem txhim kho qhov corrosion ntawm huab cua, tshwj xeeb tshaj yog cov corrosion kuj ntawm cov huab cua uas muaj chloride.
Feem ntau, lub hardness ntawm stainless hlau yog siab dua li ntawm aluminium alloy, tus nqi ntawm stainless hlau yog siab dua li ntawm aluminium alloy.
