Lub hauv paus chiv keeb ntawm 1.4541 yog dab tsi?
1.4541 yog cov khoom siv hlau tsis muaj steel nrog tus lej tshwj xeeb.
Tshwj xeeb, tus lej 1.4541 yog raws li EU BS EN tus qauv thiab sib haum rau 06Cr18Ni11Ti cov khoom ntawm Suav GB / T20878 tus qauv. Hauv Tebchaws Meskas, nws yog qhov sib npaug rau ASTM 321 cov khoom siv qib. Cov tshuaj muaj pes tsawg leeg ntawm cov khoom no suav nrog tsis pub ntau tshaj 0.08% carbon (C), tsis ntau tshaj 1.00% silicon (Si), tsis ntau tshaj 2.00% manganese (Mn), tsis ntau tshaj 0.030% sulfur (S), thiab tsis ntau tshaj 0.035% phosphorus (P)% thiab lwm yam. Vim nws zoo heev corrosion kuj thiab mechanical zog ntawm qhov kub thiab txias, 1.4541 yog dav siv nyob rau hauv kev tsim cov khoom thiab cov khoom nyob rau hauv petrochemical, hluav taws xob fais fab, choj thiab tsheb industries. Hauv keeb kwm kev txhim kho ntawm stainless hlau, 1.4541 tau tsim los daws cov teeb meem intergranular corrosion ntawm cov pa 18-8 austenitic stainless hlau. Los ntawm kev ntxiv cov khoom titanium rau kev kho kom ruaj khov, kev tsim cov chromium carbide yog tswj tau zoo, yog li txhim kho cov khoom siv lis ciam corrosion kuj thiab kub siab zog. Txoj kev loj hlob ntawm cov khoom siv no yog ua raws li kev xav ntawm chromium-tsis zoo txoj kev xav ntawm intergranular corrosion ntawm austenitic stainless hlau, thiab yog ib qho kev txhim kho thiab optimization ntawm cov khoom qub.
Piv txwv li, 1.4541 tsis yog tsuas yog cov khoom siv xwb, nws kuj sawv cev rau cov khoom siv hlau stainless uas tau raug kho tshwj xeeb los txhim kho kev ua haujlwm.
