304 stainless hlau tsis tuaj yeem tawv los ntawm kev kho cua sov. Kev kho los yog annealing tuaj yeem ua tau los ntawm kev ua kom txias sai tom qab cua sov rau 1010-1120 ° C.
Puas yog 304 stainless nyuaj rau tshuab?
Txawm tias nws muaj ntau yam zoo, Hom304 stainless hlau muaj cov yam ntxwv ua haujlwm nyuaj, vim nws txoj kev xav ua haujlwm nyuaj ntawm tus nqi nrawm heev. Txhawm rau txhim kho nws cov khoom siv, cov kws tshawb fawb tau hloov kho Hom 304 los ntawm kev ntxiv cov sulfur lossis selenium. Lub resulting stainless hlau yog hom 303.
Yuav ua li cas stainless hlau nyuaj dua 304 lossis 316?
Txawm hais tias cov hlau tsis muaj steel 304 alloy muaj cov ntsiab lus melting ntau dua, qib 316muaj cov tshuaj tiv thaiv zoo dua rau cov tshuaj thiab chlorides (xws li ntsev) dua qib 304 stainless hlau. Thaum nws los txog rau cov ntawv thov nrog cov tshuaj chlorinated los yog raug ntsev, qib 316 stainless hlau yog suav tias yog superior.
Yuav ua li cas stainless hlau tuaj yeem ua kom tawv nqaij?
Nto hardening ntawm stainless hlau tuaj yeem ua tiav los ntawm kev tshwj xeeb high- thiab qis-kub gaseous thermochemical txheej txheem uas hloov nto rau hauv N / C-expanded austenite.
Dab tsi yog qhov nyuaj ntawm stainless hlau 304?
304 steel muaj Rockwell B hardness ntawm 70; rau kev siv, Rockwell B hardness ntawm tooj liab, ib tug mos hlau, yog 51. Cias muab, 304 steel tsis nyuaj li ib co ntawm nws stainless steel cov kwv tij xws li 440 steel (saib peb tsab xov xwm ntawm 440 steel yog xav paub ntxiv), tab sis tseem tuav nws tus kheej ua lub hom phiaj tawv tawv.
