HP345 hlautau tshwm sim raws li cov khoom nyiam rau siab -siab, qaug zog- welded gas cylinders vim nws qhov sib xyaw ua ke ntawm lub zog siab (Ntau tshaj lossis sib npaug rau 345 MPa tawm los), zoo heev weldability, superior toughness, thiab pov thawj qaug zog kev ua tau zoo. Tsis zoo li qib qis dua -qib lwm yam xws li HP295, HP345 ua rau cov tuam txhab tsim khoom sib dua, muaj zog dua, thiab muaj kev nyab xeeb dua lub tog raj kheej uas tuaj yeem ua rau lub zog rov ua dua yam tsis ua haujlwm. Qhov kev tshuaj ntsuam no tshuaj xyuas cov txheej txheem tsim nyog, qhov zoo sib piv, thiab tiag - ntiaj teb daim ntawv thov uas tsim HP345 raws li tus qauv kev lag luam rau kev thov cov ntawv thov cia roj.
Hauv kev tsim cov welded gas cylinders, tshwj xeeb tshaj yog cov uas tsim los rau nruab nrab mus rau siab - kev siv siab, kev xaiv cov khoom ncaj qha txiav txim siab txog kev nyab xeeb, durability, thiab lifecycle nqi. Ntawm ntau qib steel, HP345 steel phaj tau dhau los ua qhov kev xaiv zoo tshaj vim nws qhov sib npaug ntawm lub zog, tawv, weldability, thiab qaug zog ua haujlwm.
Lub zog muaj zog ua kom muaj kev ruaj ntseg zoo nyob rau hauv siab
| Khoom | HP345 Tus nqi |
|---|---|
| Yield zog (ReL) | Ntau dua lossis sib npaug li 345 MPa |
| Tensile zog (Rm) | 510-640 MPa |
| Elongation | Ntau dua lossis sib npaug li 21% |
Vim Li Cas Nws Tseem Ceeb:
Gas cylinders ua haujlwm hauv qabkev nyuaj siab sab hauv
Higher yield zog txhais tau tias:
- Zoo dua tiv thaiv deformation
- Tsawg txoj kev pheej hmoo ntawm bulging los yog rupture
- Muaj peev xwm tiv taus kev tsim qauv siab dua
Fatigue Performance Advantages ntawm HP345
HP345 welding gas cylinder steel yog tsim tshwj xeeb rau kev ua haujlwm siab - lub voj voog qaug zog, nrog cov khoom siv tau zoo uas ua rau lub hauv paus ruaj khov rau nws txoj kev qaug zog zoo heev:
ruaj khov, Zoo-Grained Microstructure: Los ntawm kev tswj dov thiab ua kom txias txias (TMCP) txheej txheem, HP345 ua tiav ib qho kev sib xws, refined ferrite-pearlite (los yog bainite) microstructure. Cov nplej zoo tsis tsuas yog txhim kho tag nrho lub zog ntawm cov hlau, tab sis kuj ua rau muaj kev cuam tshuam kev ntxhov siab, inhibit qhov nucleation thiab nthuav dav ntawm microcracks ntawm cov ciam teb, thiab txhim kho cov khoom muaj peev xwm tiv thaiv cyclic loading.
Ultra-Cov ntsiab lus tsis zoo (P, S): HP345 nruj me ntsis tswj cov teeb meem xws li phosphorus (P) thiab sulfur (S) los ntawm cov txheej txheem smelting siab heev (xws li LF refining thiab VD nqus tsev degassing). Sulfur yog ib qho yooj yim los tsim sulfide inclusions, uas dhau los ua lub hauv paus ntawm qaug zog tawg nyob rau hauv alternating kev ntxhov siab; phosphorus yuav txo cov tawv tawv ntawm cov hlau thiab ua kom tawg tawg. Lub ultra- cov ntsiab lus tsis muaj impurity tsawg hauv paus tshem tawm qhov kev phom sij zais ntawm kev ua tsis tiav thaum ntxov.
Uniform thiab Consistent Mechanical Properties: Tag nrho cov phaj ntawm HP345 muaj lub zog tsis sib xws, toughness thiab plasticity, tsis muaj qhov sib txawv ntawm lub taub hau, lub tog raj kheej lub tog raj kheej thiab vuam cheeb tsam, kom tsis txhob muaj kev ntxhov siab hauv zos thiab tsis ua hauj lwm ntxov los ntawm cov khoom siv tsis sib xws, kom ntseeg tau tias lub tog raj kheej tuaj yeem ua haujlwm ruaj khov nyob rau hauv ntev - lub sij hawm cyclic loading.
Weldability zoo rau lub tog raj kheej kev ntseeg siab ntawm HP345 steel
Weld zoo yog qhov tseem ceeb tshaj plaws kev nyab xeeb tshaj plaws hauv kev tsim roj cylinder. Lub tog raj kheej roj ua haujlwm nyob rau hauv siab heev - cov kev mob siab, thiab lawv cov welded seams inherently lub cev tsis muaj zog ntawm tag nrho cov hlab ntsha. Txhua qhov vuam tsis xws luag, tawg, lossis kev ua haujlwm tsis zoo hauv qhov cua sov- thaj chaw cuam tshuam (HAZ) tuaj yeem ua rau muaj kev puas tsuaj loj, tawg, lossis tawg. HP345 welding gas cylinder steel yog engineered nrog ib tug weld -cov tshuaj lom neeg muaj pes tsawg leeg thiab microstructure, xa kev lag luam- ua cov weldability los lav lub sij hawm ntev - cov qauv kev ncaj ncees ntawm lub tog raj kheej roj.
Kev tsim tshuaj lom neeg rau kev ua tau zoo dua vuam
HP345's weldability kom zoo dua pib los ntawm nws cov precision - tswj cov tshuaj muaj pes tsawg leeg, uas yog optimized tshwj xeeb rau siab - siab lub tog raj kheej vuam daim ntaub ntawv:
| Qhov xwm txheej | Technical Advantage | Hauv -Kev piav qhia tob |
|---|---|---|
| Cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.20%) | Txo kev tawg rhiab heev | Cov pa roj carbon monoxide yog lub hauv paus tseem ceeb uas ua rau kom cov hlau tsis muaj zog thiab ua rau muaj kev kub ntxhov thaum lub sij hawm vuam. Los ntawm nruj me ntsis txwv cov ntsiab lus carbon tsawg dua los yog sib npaug li 0.20%, HP345 txo qis qhov tsim ntawm brittle martensite nyob rau hauv vuam thiab tshav kub- cuam tshuam cheeb tsam (HAZ), tshem tawm lub hauv paus ua rau txias tawg thiab ua kom lub ductility thiab toughness ntawm welded sib koom. |
| Tswj CE (Carbon Equivalent) | Txhim kho weld stability |
Carbon Equivalent (CE) yog ib qho tseem ceeb qhia rau kev ntsuam xyuas steel weldability. HP345 nruj me ntsis tswj CE mus rau qhov tsawg, ruaj khov ntau yam los ntawm kev sib npaug alloy tsim, kom ntseeg tau zoo ib yam vuam kev ua tau zoo thoob plaws ntau lawm batch. Qhov kev tswj hwm CE no tiv thaiv qhov tsis tuaj yeem ua kom tawv thiab tawg thaum lub sijhawm vuam, ua kom ruaj khov, rov ua dua cov txheej txheem vuam rau ntau lub tog raj kheej. |
| Micro{0}} alloying | Txhim kho HAZ toughness |
HP345 ntxiv cov lej ntawm micro-alloying cov ntsiab lus (xws li Nb, V, Ti) uas tsim tau zoo, dispersed carbonitride precipitates. Cov precipitates zoo ua kom zoo dua cov qauv nplej hauv tshav kub- thaj chaw cuam tshuam (HAZ) thaum lub sijhawm vuam, inhibiting grain coarsening ntawm qhov kub thiab txias. Qhov no ua rau muaj kev cuam tshuam zoo rau qhov hnyav thiab qaug zog ntawm HAZ, tshem tawm "tsis muaj zog txuas" ntawm lub hauv paus hlau thiab vuam seam. |
