410 Seamless Stainless Hlau Yeeb Nkab rau Kev Siv Dej
Tso lus
Dab tsi 410 Martensitic Stainless Hlau Muaj
410 stainless hlau yog martensitic chromium hlau uas muaj 11.5 mus rau 13.5 feem pua chromium nrog cov ntsiab lus siab tshaj plaws ntawm 0.15 feem pua. Nws tuaj yeem hardened los ntawm austenitizing thiab tempering, uas muab qhov sib npaug ntawm lub zog, hardness thiab nruab nrab corrosion kuj ntawm tus nqi qis dua li cov qib austenitic. Vim tias nws yog cov hlau nplaum thiab cov cua sov kho tau, 410 feem ntau xaiv qhov chaw hnav tsis kam lossis lub zog muaj zog nrog rau qhov zoo tib yam atmospheric corrosion kuj.
Seamless 410 yeeb nkab yog ib qho hollow round seem uas tsis muaj longitudinal weld. Nws yog tsim los ntawm kub tho ib puag ncig billet, ces txias txias los yog txias dov mus rau qhov kawg loj, ua raws li los ntawm kev kho cua sov, straightening thiab pickling. Qhov tsis muaj qhov vuam seam thiab cov phab ntsa zoo sib xws ua rau nws tsim nyog rau kev hloov pauv cov kua dej uas yuav tsum tau ua kom nruj nruj thiab muaj peev xwm xav tau.
Chemical Composition thiab Mechanical Properties
Hom chemistry rau ASTM A268 TP410 seamless raj yog muab hauv qab no. Corrosion kuj nyob ntawm yuav luag tag nrho ntawm cov qib chromium, uas ua rau nws tus kheej kho cov zaj duab xis passive ntawm qhov chaw thiab tiv thaiv cov hlau matrix hauv cov xov xwm me me.
| Element | Kev sib xyaw, feem pua |
|---|---|
| Cov pa roj carbon | 0.15 max |
| Manganese | max 1.00 Nws |
| Phosphorus | 0.040 max |
| Sulfur | 0.030 max |
| Silicon | max 1.00 Nws |
| Chromium | 11.5-13.5 Nws |
Nyob rau hauv cov xwm txheej annealed, ASTM A268 TP410 tube nqa lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa, qhov tsawg kawg nkaus 0.2 feem pua cov pov thawj lub zog ntawm 205 MPa thiab qhov tsawg kawg nkaus elongation ntawm 20 feem pua, nrog qhov siab tshaj plaws hardness nyob ib ncig ntawm 217 HBW. quenching thiab tempering nce tensile lub zog zoo tshaj cov nuj nqis no thaum txo cov ductility, yog li cov khoom xa tuaj yuav tsum tau teev rau ntawm qhov kev txiav txim.
Yog 410 Pipes haum rau kev xa cov kua
Yog, hauv nws lub hnab ntawv kev pabcuam. Uniform phab ntsa thickness thiab ib tug du, scale free bore qis ndlwg tsis kam thiab txhim khu kev hloov efficiency, thaum lub zog siab dua ntawm martensitic steel tso cai rau ib tug nyias phab ntsa dua ib tug austenitic yeeb nkab ntawm tib lub siab ntsuas. Cov ntaub ntawv tuav tau zoo nyob rau hauv atmospheric raug, dej tshiab, me me organic media thiab ntau roj av khoom, uas yog vim li cas nws yog lug siv rau industrial hloov kab.
Cov kev txwv yuav tsum raug hwm. Qib 410 tsis yog tsim rau cov kua qaub uas muaj zog, kub siab ua kom sov, lossis cov tshuaj chloride nplua nuj xws li dej hiav txwv, qhov chaw pitting tuaj yeem pib ntawm cov tshuaj chloride siab tshaj li 200 ppm. Kev pabcuam txuas ntxiv saum toj li 600 C kuj raug zam vim tias lub zog tempered ntog thiab ua kom nrawm nrawm. Qhov twg welded tsim yog tsim nyog, preheat thiab tom qab weld kev kho cua sov yog ib txwm yuav tsum tau kom tsis txhob muaj ib tug nyuaj, tawg rhiab martensitic tshav kub cuam tshuam cheeb tsam.
Txoj kev tsim khoom, qhov ntau thiab tsawg thiab kam rau ua
Cold drawn 410 raj yog tsim los ntawm kub tho, pickling, txias kos duab hla lub mandrel, annealing, straightening thiab zaum kawg xov. Qhov ntau thiab tsawg yog tsim los txiav txim nrog lub hnab ntawv hauv qab no.

Daim Ntawv Thov thiab Kev Pabcuam txwv
Kev sib xyaw ua ke ntawm lub zog, hardness thiab nruab nrab corrosion kuj ua rau 410 seamless yeeb nkab hauv kev thov thoob plaws kev lag luam.
Cov kab hloov pauv hauv cov roj av, petrochemical thiab cov nroj tsuag tshuaj
Txheej txheem dej, coolant thiab tsis tshua muaj siab hydraulic circuits
Cov khoom siv kho mob, kev lag luam khoom noj piping thiab cov kev pabcuam kev lag luam teeb
Mechanical instrument tubing thiab mechanical structural Cheebtsam
Twj shafts, valve trim, cylinder chim thiab bushings qhov twg hardness yuav tsum tau
Thaum tshav kub kub exchanger thiab condenser raj ua hauj lwm nrog me me, tsis tshua muaj chloride media
Rau cov tshuaj chloride bearing lossis acidic lub luag haujlwm, 316L lossis duplex lwm qhov yuav tsum tau ntsuas qhov hloov pauv, vim tias 11.5 mus rau 13.5 feem pua ntawm chromium qib 410 tsuas yog muaj qhov nruab nrab pitting kuj.
Cov lus nug nquag
Q: 410 stainless hlau yeeb nkab puas tuaj yeem nqa cov kua dej nyab xeeb?
Yog lawm. Seamless 410 yeeb nkab yog siv tsis tu ncua rau roj av, tshuaj, kev kho mob, khoom noj khoom haus thiab lub teeb kev lag luam hloov kab, muab qhov nruab nrab yog me me thiab qhov kub thiab txias nyob rau hauv cov khoom txwv.
Q: Vim li cas 410 suav tias yog hlau nplaum?
Nws muaj lub cev martensitic nyob nruab nrab ntawm lub cubic qauv, yog li nws yog sib nqus nyob rau hauv ob qho tib si annealed thiab hardened mob, tsis zoo li 304 los yog 316 austenitic qib.
Q: Qhov siab tshaj plaws ua haujlwm kub yog dab tsi?
Kev pabcuam txuas ntxiv yog feem ntau khaws cia qis dua 600 C, vim tias tempering txo lub zog thiab oxidation scaling nce siab tshaj qib ntawd.
Q: Puas yog 410 haum rau kev pabcuam dej hiav txwv?
Tsis yog. chloride nplua nuj xov xwm ua rau pitting thiab crevice corrosion; siv 316L lossis qib duplex rau dej hiav txwv thiab dej hiav txwv.
Q: Puas yog 410 yeeb nkab xav tau kev kho cua sov tom qab vuam?
Vuam tsim ib qho nyuaj martensitic cheeb tsam, yog li preheat thiab tom qab vuam kev kho cua sov yog ib txwm teev kom rov qab ductility thiab txo qhov kev pheej hmoo tawg.
Q: Cov qauv dab tsi npog 410 seamless raj?
ASTM A268 TP410 npog seamless thiab welded ferritic thiab martensitic raj, ASTM A276 npog bar Tshuag ntawm hom 410 thiab ASTM A511 npog seamless mechanical tubing.
