waht yog 304 stainless hlau phaj?

Date:Jul 13, 2019

304 stainless hlau yog cov khoom siv ntau yam hauv cov hlau stainless nrog qhov ceev ntawm 7.93 g / cm3, tseem hu ua 18/8 stainless hlau. Nrog siab kub tsis kam ntawm 800 ° C, nws muaj cov kev ua haujlwm zoo thiab siab toughness. Nws yog dav siv nyob rau hauv kev lag luam thiab rooj tog kho kom zoo nkauj kev lag luam thiab khoom noj khoom haus kho mob kev lag luam.

304 yog qhov muaj peev xwm siv tau ntau yam steel hlau uas yog dav siv los ua cov cuab yeej thiab qhov chaw uas xav tau kev ua tau zoo tag nrho (kev ua hauj corrosion thiab cov qauv). Txhawm rau kom muaj qhov kev tiv thaiv xeb ua haujlwm hauv stainless hlau, cov hlau yuav tsum muaj ntau dua 18% chromium thiab ntau dua 8% npib tsib xee. 304 stainless hlau yog qeb ntawm stainless hlau ua raws li American ASTM qauv.

Cov ntsiab lus tseem ceeb tshaj plaws hauv 304 yog Ni, Cr, tab sis tsis txwv rau ob yam no. Cov kev qhia tshwj xeeb tau teev tseg los ntawm cov qauv khoom. Cov kev txiav txim siab thoob plaws hauv kev lag luam xav tias ntev li ntev tau cov ntsiab lus Ni ntau dua 8% thiab cov ntsiab lus Cr yog ntau dua 18%, nws tuaj yeem suav tias yog 304 stainless hlau. Qhov no yog vim li cas kev lag luam hu hom hom hlau no 18/8 stainless hlau. Qhov tseeb, cov qauv txheej txheem cov khoom lag luam muaj cov kev cai zoo heev rau 304, thiab cov qauv khoom lag luam no muaj qee qhov sib txawv rau cov duab sib txawv ntawm cov hlau tsis huv.

304 stainless hlau yog cov feem ntau siv cov chromium-nickel stainless hlau. Raws li cov khoom siv dav siv hlau, nws muaj kev txhim kho zoo corrosion, thaum tshav kub kub tsis tshua muaj zog, tsis tshua muaj zog kub thiab cov cuab yeej muaj zog. Nws muaj cov kub zoo ua haujlwm xws li stamping thiab khoov. , tsis muaj kev kho cua sov ua kom tawv tawv (siv kub -196 ° C ~ 800 ° C). Corrosion tiv taus nyob rau hauv huab cua, yog tias nws yog huab cua kev lag luam lossis thaj chaw muaj kuab paug ntau, nws yuav tsum tau tu lub sijhawm kom tsis txhob xeb. Haum rau kev ua, khaws thiab thauj khoom noj. Nws Muaj cov khoom ua zoo ua zoo thiab solderability.
