Qhov tseeb nyias-phab ntsa stainless hlau yeeb nkab hauv Tshuag
304 txoj kab uas hla loj stainless hlau yeeb nkab yog ib hom hlau alloy siab uas tuaj yeem tiv taus corrosion hauv huab cua lossis tshuaj lom neeg corrosion nruab nrab. 304 stainless hlau yeeb nkab muaj qhov zoo nkauj thiab zoo corrosion kuj. Nws tsis tas yuav raug kho saum npoo xws li xim plating, tab sis muab kev ua si tag nrho rau qhov kev ua tau zoo ntawm cov hlau tsis huv thiab siv ntau yam ntawm cov hlau.
9% nickel, 19% chromium, stainless hlau, kub-resistant hlau
Feem ntau hu ua stainless hlau. Cov khoom sawv cev muaj xws li 13 chromium steel, 18-8 chromium nickel steel thiab lwm yam hlau alloy siab. Los ntawm kev xav ntawm metallography, vim hais tias stainless hlau muaj chromium, ib tug nyias chromium zaj duab xis yog tsim nyob rau saum npoo, uas yog sib cais los ntawm cov oxygen invaded nyob rau hauv cov hlau thiab plays lub luag hauj lwm nyob rau hauv corrosion kuj. Yuav kom tswj tau qhov kev tiv thaiv corrosion ntawm stainless hlau, cov hlau yuav tsum muaj ntau tshaj 12% chromium. 304 yog ib qho universal stainless hlau, uas yog dav siv los ua cov cuab yeej thiab cov khoom uas xav tau kev ua haujlwm zoo (corrosion resistance and formability). 304 stainless hlau yog ib hom ntawm stainless hlau ua raws li American ASTM cov qauv. 304 yog sib npaug rau 0Cr19Ni9 (0Cr18Ni9) stainless hlau hauv Suav teb. 304 muaj 19% chromium thiab 9% npib tsib xee. 304 yog feem ntau siv stainless hlau thiab kub-resistant hlau. Rau cov khoom siv khoom noj khoom haus, Xitong chemical khoom, nuclear zog, thiab lwm yam chemical muaj pes tsawg leeg specification ntawm 304 stainless hlau C Si Mn ps Cr Ni (nickel) Mo SUS304 ≤ 0.08 ≤ 1.00 ≤ 2.00 ≤ 0.05 ≤ 0.03 18.00-20.500 ~ 10.00
