Kev xaiv ntawm steel lub puab tsaig xauv yog feem ntau ua ke ntawm lub zog, durability, corrosion kuj thiab processability. Cov ntaub ntawv tseem ceeb yog stainless hlau (xws li . 304 stainless hlau) thiab carbon steel (xws li T8 carbon steel thiab 20Cr steel). Nyob ntawm cov yam ntxwv ntawm cov khoom siv thiab nws qhov zoo, cov hauv qab no raug tshuaj xyuas:
I. Hom thiab yam ntxwv
Stainless hlau
Tus neeg sawv cev zoo: 304 Stainless Hlau (Ntau dua lossis sib npaug rau 10.5% chromium thiab 8% -10.5% nickel)
Core Advantages:
Corrosion Resistance: Ib qhov ntom ntom chromium oxide zaj duab xis tsim rau ntawm qhov chaw, tiv taus ya raws, ntsev pos huab thiab microacidic lossis alkaline ib puag ncig rau sab nraum zoov, tshuaj lom neeg thiab dej hiav txwv. Piv txwv li, 304 stainless hlau ceev- tso tawm clip tsis xeb tom qab ntau tshaj 48 teev nyob rau hauv kev ntsuam xyuas ntsev tsuag, ua rau nws haum rau mus pw hav zoov los yog caij tsheb kauj vab nyob rau hauv lub los nag.
Lub zog siab thiab kev puas tsuaj: Lub zog hnyav (HRC Tsawg dua lossis sib npaug ntawm 35), kev sib zog ua ke nrog khawb tsis kam, haum rau nquag qhib thiab kaw xauv.
Mechanical zog: Yooj yim rau xuas nrig ntaus thiab vuam, tuaj yeem tsim cov qauv precision (xws li fixtures nrog tus kheej -locking function) kom tau raws li cov qauv tsim. Cov pa roj carbon steel
Piv txwv li: T8 carbon steel, 20Cr steel
Core Advantages:
High Hardness thiab abrasion tsis kam: T8 steel yog tshav kub kho rau HRC50-55 hardness thiab tsim nyog rau kev tsim lub puab tsaig siab (xws li hydraulic clamps); 20Cr steel tuav zoo abrasion kuj txawm nyob rau hauv HRC44 thiab feem ntau yog siv nyob rau hauv cov yeeb nkab ciaj ntswj clamping pab kiag li lawm.
Tus nqi-Kev ua tau zoo: Cov khoom siv roj carbon hlau tsis tshua muaj nqi ntau dua li cov hlau tsis muaj steel thiab yog li tsim nyog rau tus nqi-rhiab heev tab sis siab- muaj zog siv kev lag luam (xws li kev tsim kho thiab kev tsim tshuab).
Kev Kho: Qee cov pa roj carbon steel, xws li pliers, tuaj yeem kho nrog Colmano vuam, txuas lawv lub neej kev pab cuam.
ii. Cov txheej txheem xaiv cov khoom siv
Environmental adaptability: Yog hais tias lub latch xav tau ntev raug rau ntub thiab corrosive ib puag ncig (xws li tshuaj thiab hluav taws xob industries), stainless hlau (xws li 304 stainless hlau rau -bar xauv) yog qhov zoo dua, vim nws cov xeb kuj ua kom lub neej muaj txiaj ntsig ntau dua 10 xyoo.
cov ntaub ntawv carbon steel (xws li T8 steel clasps) ua tau raws li qhov yuav tsum tau ua thiab raug nqi ntau dua - siv tau rau qhov qhuav, tsis tshua muaj - corrosion nyob rau hauv ib puag ncig (xws li lub Hoobkas tswj cov khoom siv). Load thiab Friction Requirements: High- kev sib txhuam daim ntawv thov (xws li, tso lub tes tsho ntawm hydraulic clamps) yuav tsum siab -hardness carbon steel (xws li, 20Cr steel) kom txo cov hniav thiab txhim kho puas.
Stainless hlau muab superior toughness thiab qaug zog tiv thaiv rau latches (xws li multi- cuab tam pliers) uas yuav tsum tau nquag qhib thiab kaw los yog raug rau dynamic loads.
Kev ua haujlwm thiab tus nqi sib npaug: Stainless hlau yog tsim rau precision manufacturing (xws li tus kheej -locking fixtures), tab sis tus nqi ua yog siab. carbon steel tuaj yeem txhim kho kev ua tau zoo los ntawm carburizing, quenching, thiab lwm yam, thiab tsim nyog rau ntau lawm.
