Ordinary txias-dov daim ntawv SPCC SPCC hais txog cov hlau ingot uas txuas ntxiv dov mus rau hauv qhov xav tau tuab ntawm steel phaj coil lossis cov ntaub ntawv los ntawm lub tshuab txias txias. Qhov saum npoo ntawm SPCC tsis muaj kev tiv thaiv thiab yooj yim oxidized thaum raug huab cua, tshwj xeeb tshaj yog nyob rau hauv huab cua puag ncig uas cov oxidation tus nqi nrawm thiab tsaus liab xeb tshwm. Qhov saum npoo yuav tsum tau pleev xim rau, electroplated, lossis lwm yam kev tiv thaiv thaum siv.
Lub substrate ntawm galvanized steel phaj SECC SECC yog ib tug general txias-kuav los tiag steel kauj, uas yog ib tug electrogalvanized khoom tom qab undergoing degreasing, pickling, electroplating, thiab ntau yam kev kho mob tom qab ib tug tas mus li electrogalvanizing ntau lawm kab. SECC tsis tsuas yog muaj cov khoom siv kho tshuab thiab cov txheej txheem zoo sib xws ntawm cov ntawv txias txias txias, tab sis kuj muaj kev tiv thaiv corrosion zoo dua thiab zoo nkauj zoo nkauj. Nws muaj kev sib tw zoo thiab kev hloov pauv hauv kev ua lag luam ntawm cov khoom siv hluav taws xob, khoom siv hauv tsev, thiab rooj tog zaum. Piv txwv li, SECC feem ntau yog siv hauv computer chassis.
Kub-dip galvanization steel ntawv SGCC Kub-dip galvanization steel kauj yog hais txog cov khoom ua tiav tom qab kub dov thiab pickling lossis txias dov, tom qab ntxuav thiab annealing, raus hauv cov tshuaj zinc da dej nrog qhov kub ntawm txog 460 degree C, yog li tias cov ntawv hlau yog coated nrog zinc, thiab tom qab ntawd quenched, tempered, leveled thiab chemically kho. SGCC cov ntaub ntawv nyuaj dua li cov khoom siv SECC, nrog cov khoom siv tsis zoo (tsis txhob sib sib zog nqus kos duab), zinc txheej tuab, thiab tsis zoo weldability.
Stainless hlau SUS301 muaj qis Cr (chromium) cov ntsiab lus thiab tsis zoo corrosion kuj piv rau SUS304. Txawm li cas los xij, tom qab ua haujlwm txias, nws tuaj yeem ua tau zoo tensile lub zog thiab hardness, thiab muaj elasticity zoo. Nws yog tsuas yog siv rau lub caij nplooj ntoos hlav caij nplooj ntoos hlav thiab tiv thaiv EMI.
Stainless hlau SUS304 yog ib qho ntawm feem ntau siv stainless hlau. Vim nws muaj Ni (nickel), nws muaj peev xwm tiv taus corrosion thiab kub dua li cov hlau uas muaj Cr (chromium). Nws muaj cov cuab yeej zoo heev, tsis muaj kev kho cua sov, thiab tsis muaj elasticity.
