Kev paub txog Stainless Hlau 410

Stainless hlau 410 yog cov feem ntau martensitic stainless hlau, muaj 11.5-13.5% chromium. Nws yog cua sov- kho tau, muab lub zog siab thiab hardness tom qab quenching thiab tempering, thaum muab qhov yooj yim corrosion kuj. Nws yog dav siv nyob rau hauv daim ntawv thov xav tau ob qho tib si txhua yam muaj zog thiab nruab nrab xeb kuj.

Tshuaj muaj pes tsawg leeg (Key, % ASTM A240)C: 0.08–0.15; Cr: 11.50–13.50 Nws. Mn: Tsawg dua lossis sib npaug li 1.00; Si: Tsawg dua lossis sib npaug li 0.50

Mechanical Properties (Kub-Kho)Tensile Strength: Ntau dua lossis sib npaug ntawm 620 MPa; Yield zog: Ntau dua lossis sib npaug rau 415 MPa; Elongation: Ntau dua lossis sib npaug li 15%; Hardness: Tsawg dua los yog sib npaug rau 241 HB (annealed), mus txog 40 HRC (kub-kho)

Kev ua tau zoo & Kev sivQhov zoo: Thaum tshav kub kub- kho tau, siab zog / hardness, zoo hnav tsis kam. Daim ntaub ntawv: li qub, twj tso kua mis, fasteners, cutlery, cov cuab yeej phais, tshuab qhov chaw.

5 Quick Q&As

1. Dab tsi ua rau 410 martensitic stainless hlau, thiab vim li cas qhov ntawd tseem ceeb?Martensitic stainless hlau zoo li 410 muaj cov qauv siv lead ua (martensite) tsim los ntawm cua txias (quenching) tom qab cua sov. Cov qauv no muab 410 cua sov-kev kho tau- tsis zoo li qib ferritic (piv txwv li, 409), nws tuaj yeem ua rau 40 HRC, ua rau nws muaj zog txaus rau kev thauj khoom-cov kabmob xws li li qub. Martensite kuj muab kev hnav tsis kam, tseem ceeb rau cov khoom xws li cov twj tso kua mis uas rub tawm tsam lwm qhov. Yog tsis muaj cov qauv no, 410 yuav tsuas muaj lub zog nruab nrab, txwv tsis pub nws siv hauv siab - kev siv kev ntxhov siab.

2. Kev kho cua sov cuam tshuam li cas rau 410 lub zog?Annealing (cua sov rau 815-900 degree, txias qeeb) softens 410, txo hardness tsawg dua los yog sib npaug rau 241 HB rau fabrication (xws li, khoov, machining). quenching (cua sov rau 925-1010 degree, dej txias) ua cov martensite nyuaj, nce hardness tab sis ua rau nws nkig. Tempering (cua sov quenched steel rau 150-650 degree) sib npaug zog thiab toughness -tempering ntawm 300℃muab siab hardness (35-40 HRC) rau cutlery, thaum tempering ntawm 600℃txo hardness mus rau 25 HRC tab sis boosts toughness rau tshuab qhov chaw. Qhov no versatility ua rau 410 haum rau ntau yam kev siv.

3. Puas yog 410 corrosion-resistant txaus rau siv sab nraum zoov?410 muaj qhov yooj yim corrosion kuj- zoo dua li cov pa roj carbon steel tab sis tsawg dua cov qib austenitic xws li 304. Nws tiv taus xeb hauv huab cua hauv qhov chaw qhuav lossis ntub dej (xws li, cov tshuab hauv tsev) tab sis tuaj yeem xeb hauv ntub dej, ntsev, lossis cov cua hauv tsev. Rau kev siv sab nraum zoov hauv thaj chaw ntug dej hiav txwv, 410 yuav pit thiab corrode vim muaj cov tshuaj chloride. Txhawm rau txhim kho kev ua haujlwm sab nraum zoov, 410 tuaj yeem pleev xim rau (xws li, nrog cov xim) lossis hloov nrog cov qib siab dua -chromium xws li 430. Nws yog qhov zoo tshaj plaws siv hauv tsev lossis kev tiv thaiv sab nraum zoov.

4. Vim li cas 410 siv rau cov cuab yeej phais?410's cua sov-kev kho mob tso cai rau nws ua kom tawv nqaij mus rau theem uas khaws cov ntug ntse (tseem ceeb rau cov tawv nqaij) thaum tseem nyob ruaj khov. Nws tsis yog - lom thiab tuaj yeem ua kom tsis muaj menyuam ntau zaus (ntawm autoclaving) yam tsis muaj degrading - nws cov chromium oxide txheej tiv thaiv corrosion los ntawm kev kho mob kev daws teeb meem. Tsis zoo li austenitic qib zoo li 316 (uas yog corrosion ntau dua-resistant tab sis tsis nyuaj), 410 sib npaug sharpness, lub zog, thiab biocompatibility, ua rau nws raug nqi -zoo rau cov khoom siv phais pov tseg lossis rov siv tau.

5. 410 piv rau 420 li cas hauv lub zog thiab corrosion kuj?420 muaj cov ntsiab lus carbon ntau dua (0.15–0.40% vs . 0.08–0.15% rau 410), yog li nws tuaj yeem ua rau tawv tawv dua (txog 50 HRC vs . 40 HRC rau 410) thiab muaj kev hnav zoo dua. Qhov no ua rau 420 zoo tagnrho rau siab -cov khoom xws li riam hniav. 410, nrog cov pa roj carbon tsawg, muaj qhov zoo me ntsis ductility thiab weldability dua li 420. corrosion kuj zoo ib yam rau ob qho tib si, vim lawv muaj tib chromium ntau yam (11.5-13.5% rau 410, 12-14% carbon ntau dua rau 420% yog tias tsis yog ntau dua rau 420%). kom raug kub- kho.
