Dab tsi yog qhov sib txawv ntawm 440A 440B thiab 440C stainless hlau?
Tso lus
Niaj hnub no, Kuv yuav qhia cov khoom raw nrov tshaj plaws hauv cov cuab yeej kev lag luam, uas yog 440A (940B (940C (9CR18MO). Kuv yuav tshuaj ntsuam qhov sib txawv ntawm ntau qhov thiab cia siab tias nws yuav pab tau koj!
Lub ntsiab sib txawv ntawm peb cov khoom nyob hauv cov ntsiab lus carbon, thiab ntxiv rau ntawm molybdenum thiab vanadium ntsiab rau 440A stainless hlau.
Tshwj xeeb, feem ntau siv Qib 44 {{0 c yog cov ntsiab lus ntawm cov roj carless nrog {}}%. Nws muaj me ntsis molybdenum cov ntsiab lus thiab yog qhov zoo ntawm stainless hlau nrog muaj xeb muaj xeb.
Cov qauv ntawm daim ntawv thov ntawm 440C stainless hlau: 440C feem ntau yog siv los tsim cov kabmob uas ua haujlwm thiab lubricated muaj zog oxidizing cua. 440C muaj cov ntsuas hluav taws xob zoo nyob ruaj khov, yog li nws tseem tuaj yeem siv los ua corrosion-resistant kub-kub bear steel. Ib qho ntxiv, nws kuj tseem siv tau los tsim cov riam zoo, txiab, pob txiab, thiab lwm yam.
Tshuaj lom neeg muaj pes tsawg leeg ntawm 440C stainless hlau:
Cov pa roj carbon c: {{0. {95-1. 1
Silicon Si: tsawg dua los yog sib npaug rau 0. 8
Manganese MN: Tsawg dua lossis sib npaug rau 0. 8
Sulphur S: Tsawg dua lossis sib npaug rau 0. 030
Phosphorus p: tsawg dua lossis sib npaug rau 0. 035
Chromium cr: 16. {0-18. 0
Nickel Ni: tsawg dua los yog sib npaug rau 0. 6
Molybdenum mo: {0. {4-0. 7
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm 440C Stainless Hlau:
Hardness: tsawg dua los yog sib npaug rau 269hb
Quenching thiab tempering: ntau dua los yog sib npaug rau 58hrc
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab ntawm 440C Stainless Hlau:
Kev ntxhov siab sab hauv (250 n / hli2)
Tensile lub zog (560 n / hli2)
El (18%) HB (250)
440 Nta: High-zog txiav cov cuab yeej hlau, me ntsis cov ntsiab lus muaj zog carbon, hardness tuaj yeem ncav cuag 58hrc, thiab yog ib qho nyuaj tshaj plaws stainless hlau. Cov ntawv thov piv txwv feem ntau yog "chais plaub hau". Muaj peb feem ntau siv cov qauv: 440A, 440B, 440C, thiab 440F (yooj yim rau txheej txheem).
