Tso lus

1.4104 stainless hlau, feem ntau hu ua 430F los yog UNS S43020, yog ib qho dawb -machining ferritic stainless hlau tshwj xeeb tsim rau siab -machining daim ntawv thov. Nrog nws cov sulfur ntxiv rau kev txhim kho machinability, nws muaj cov machinability zoo heev thaum tuav cov corrosion kuj zoo thiab txhua yam khoom zoo ib yam li tus qauv 430. Qhov no ua rau nws cov khoom ntawm kev xaiv rau precision Cheebtsam uas yuav tsum tau complex machining, xws li screws, txiv ntseej, bolts, thiab fittings, qhov ntau lawm efficiency thiab nqi -effectiveness yog ib qho tseem ceeb.

Machinability zoo heev:Ib qho ntawm cov hlau tsis zoo tshaj plaws, nrog rau machinability kwv yees li 85% ntawm B1112 steel, siab dua tus qauv 430 (65%) thiab 304 (45%), tso cai rau kev ua haujlwm siab -ceev machining, lub neej ntev dua, thiab kev ua tiav zoo tshaj plaws.

Zoo Corrosion Resistance nyob rau hauv ib puag ncig me me:Muab kev tiv thaiv corrosion zoo ib yam li tus qauv 430, haum rau cov huab cua sab hauv tsev, dej tshiab, thiab cov tshuaj me me, tab sis tsis pom zoo rau cov dej hiav txwv los yog qhov chaw muaj corrosive hnyav.

Sib nqus thiab tsis-Hardenable:Muaj zog sib nqus thiab tsis teb rau kev kho cua sov rau hardening, ua rau nws haum rau daim ntaub ntawv uas yuav tsum tau zoo ib yam khoom yam tsis muaj kev kho cua sov.

Zoo Mechanical Properties:Ua kom muaj zog txaus thiab ductility rau feem ntau cov khoom siv machined.

Fasteners thiab Fittings:Screws, txiv ntseej, bolts, studs, thiab threaded Cheebtsam ua los ntawm kev siab -machining ceev.

Precision Cheebtsam:Solenoid Cheebtsam, ntsuas qhov chaw, thiab precision shafts.

Automotive:Sensor vaj tse, roj txhaj tshuaj, thiab ntau yam machined qhov chaw.

Hluav taws xob:Relay Cheebtsam, switchgear qhov chaw, thiab sib nqus Circuit Court Cheebtsam.

General Engineering:Cheebtsam qhov twg machinability yog qhov tseem ceeb tshaj qhov siab tshaj plaws corrosion kuj.

Pneumatic Cheebtsam:Fittings thiab connectors xav tau machinability zoo.

Qhov zoo tshaj plaws yog machinability. 430F tshwj xeeb yog tsim los rau kev ua haujlwm dawb nrog cov tshuaj sulfur ntxiv, tso cai rau kev txiav nrawm dua, lub neej ntev ntawm cov cuab yeej siv, kev ua kom zoo dua qub, thiab cov nqi tsim khoom qis dua piv rau tus qauv 430. Thaum 430 muaj qhov zoo dua corrosion kuj me ntsis vim tsis muaj sulfide suav nrog, qhov sib txawv yog tsawg heev nyob rau hauv feem ntau ib puag ncig . 430 cov khoom siv siab dua . 430 F efficiency yog qhov tseem ceeb. Rau cov ntawv thov uas xav tau qhov siab tshaj plaws corrosion kuj los yog qhov chaw ua kom tiav qhov kev ncaj ncees yog qhov tseem ceeb (xws li cov ntaub ntawv kho kom zoo nkauj), tus qauv 430 yuav tsim nyog dua.

Cov ntsiab lus sulfur siab (Ntau dua lossis sib npaug li 0.15%) uas txhim kho kev ua haujlwm kuj tseem tsim cov manganese sulfide inclusions, uas tuaj yeem ua raws li qhov chaw pib rau pitting corrosion. Qhov no txo qhov kev tiv thaiv corrosion tag nrho piv rau tus qauv 430. Yog li ntawd, 430F tsis pom zoo rau qhov chaw muaj corrosive heev, cov ntawv thov yuav tsum tau ua kom tiav qhov kev ntseeg siab rau kev tiv thaiv corrosion, los yog qhov chaw yuav raug chlorides, acids, los yog marine tej yam kev mob. Rau cov ntawv thov no, tus qauv 430 lossis lwm qib uas muaj kev tiv thaiv corrosion zoo dua yuav tsum raug txiav txim siab.

430F muaj cov yam ntxwv zoo machining xws li:

Ua kom luv luv, tawg chips uas yooj yim tshem tawm ntawm qhov chaw txiav

Tso cai rau kev txiav nrawm dua li tus qauv 430 (txog 30% sai dua)

Muab cov npoo zoo kawg nkaus nrog kev xaiv cov cuab yeej tsim nyog

Txo cov cuab yeej hnav, ncua lub neej ntawm cov cuab yeej

Nws tuaj yeem ua tau siv ob qho tib si carbide thiab siab -cov cuab yeej steel ceev

Haum rau tsis siv neeg ntsia hlau tshuab ua haujlwm

Zoo rau tapping, threading, drilling, thiab tig ua haujlwm
