Tshuaj muaj pes tsawg leeg
| Element | Limit (tseem) | Lub hom phiaj rau kev cia roj |
|---|---|---|
| C (Carbon) | Tsawg dua lossis sib npaug li 0.18–0.20% | Tsawg C ua kom zoo weldability & qis txias -kev pheej hmoo tawg; zam qhov nyuaj, nkig zones hauv welds |
| Manganese (Mn) | ~1.00% | Txhim kho yam tsis poob ductility; txhim kho toughness & qaug zog lub neej |
| Si (Silicon) | Tsawg dua lossis sib npaug li 0.35% | Txhim kho lub zog, deoxidizes, txhim kho corrosion kuj |
| P, S (Impurities) | P Tsawg dua lossis sib npaug rau 0.025%, S Tsawg dua lossis sib npaug li 0.015% | Ultra- tsis muaj impurities tiv thaiv brittleness, inclusions, thiab weld defects |
| Al (Aluminium) | Ntau dua lossis sib npaug li 0.015% | Refines nplej → finer, tougher microstructure |
Tsawg heev Ceq=weldability zoo heev (tsis xav tau preheat feem ntau)
Qhov tseem ceeb rau cov roj thooj voos kheej kheej: welds yog # 1 kev nyab xeeb - cov khoom tseem ceeb
Mechanical Properties Tuned for Pressure Vessels
HP295 uawb 6653(Suav lub tog raj kheej steel qauv) nrog lub zog sib npaug-plasticity profile:
- Yield Strength (YS): Ntau dua los yog sib npaug rau 295 MPa → Resistant deformation nyob rau hauv 1.6-2.1 MPa ua hauj lwm siab (LPG kev pab)
- Tensile Strength (TS): 440-560 MPa → Muaj zog txaus rau lub siab ntim tab sis tsis nkig
- Elongation (A5): Ntau dua lossis sib npaug li 26% (t Ntau dua lossis sib npaug li 3 hli) → Cov ductility heev rau qhov sib sib zog nqus - kos lub tog raj kheej lub cev tsis muaj qhov tawg
- Yield Ratio (YS / TS): Tsawg dua lossis sib npaug ntawm 0.75-0.8 → Dav yas deformation ntau yam → cov ntaub ntawv yooj yim, tiv taus tearing hauv stamping / flanging
Qhov nyiaj tshuav no ua rau HP295 tsim tau ntau dua li HP325 / HP345 thiab muaj zog dua li HP265-zoo tagnrho rau LPG lub tog raj kheej tsim.

Zoo heev Corrosion Resistance Ntawm HP295 Hlau
HP295 steel, raws li qib siab rau cov nkoj siab xws li LPG lub tog raj kheej, boasts zoo heev corrosion kuj, uas yog ib qho tseem ceeb lav rau nws ntev -lub sij hawm kev nyab xeeb kev pab cuam nyob rau hauv roj cia thiab tsheb thauj mus los scenarios. Nws cov corrosion kuj tsis yog tsuas yog muab los ntawm kev tshawb fawb tshuaj muaj pes tsawg leeg tsim tab sis kuj optimized los ntawm nruj ntau lawm txheej txheem, ua rau nws muaj peev xwm tiv taus ntau yam hnyav ib puag ncig thiab ua hauj lwm tej yam kev mob thiab zoo mus cuag lub neej kev pab cuam ntawm cov khoom.
Kev tswj hwm ntawm cov tshuaj muaj pes tsawg leeg nteg lub hauv paus rau HP295's corrosion kuj. Nrog rau ib qho ultra- cov ntsiab lus tsis zoo (phosphorus Tsawg dua lossis sib npaug li 0.025%, sulfur Tsawg dua lossis sib npaug li 0.015%), nws zam kev tsim cov corrosion- cov khoom sib xyaw ua ke, uas yuav ua rau muaj kev xeb hauv zos thiab ua kom cov khoom puas tsuaj. The appropriate addition of silicon (<=0.35%) and manganese (~1.00%) not only enhances the steel's strength and toughness but also forms a dense oxide film on the surface, acting as a barrier to isolate the steel matrix from corrosive media such as moisture, oxygen, and acidic substances in the air.
Hauv kev siv tswv yim, HP295 steel nthuav tawm zoo heev atmospheric corrosion kuj. Txawm hais tias siv sab nraum zoov lossis hauv qhov chaw ntub dej, nws tuaj yeem tiv thaiv xeb thiab xeb los ntawm nag, dej lwg, thiab cov pa taws ua haujlwm, tswj kev ncaj ncees ntawm cov hlau nto ntev. Rau cov khoom siv roj cia xws li LPG lub tog raj kheej, uas feem ntau raug rau huab cua qhib thiab thauj mus los ntawm cov cheeb tsam sib txawv, qhov kev ua tau zoo no tiv thaiv corrosion -induced thinning ntawm lub tog raj kheej phab ntsa thiab muaj peev xwm to.
Ntxiv mus, HP295 steel tuaj yeem tiv taus qhov kub thiab txias ntawm -40℃mus rau +60℃yam tsis muaj embrittlement lossis corrosion degradation, hloov mus rau ntau yam kev nyab xeeb. Thaum nyob rau hauv kev sib cuag nrog LPG los yog lwm yam kua roj, nws qhia tau hais tias zoo compatibility, tsis reacting nrog cov roj los tsim corrosive tshuaj, los yog corroded los ntawm kab impurities nyob rau hauv cov roj. Nws cov kev tiv thaiv corrosion kuj txo qhov kev xav tau ntawm kev saib xyuas tsis tu ncua thiab tiv thaiv - kev kho corrosion, txo tus nqi siv tag nrho thaum ua kom muaj kev nyab xeeb mus ntev thiab kev ntseeg siab ntawm cov khoom siv roj cia.
Zoo Weldability Ntawm HP295 Hlau
Lub fabrication ntawm roj thooj voos kheej kheej cia siab heev rau vuam los tsim lub plhaub thiab sib sau ua ke. HP295 tus qauv tsim muaj qhov tseem ceeb tshaj plaws weldability, lub hauv paus ntawm nws qhov kev ua tau zoo.
Tsawg Carbon Equivalent (CEV):Cov pa roj carbon tsawg thiab cov ntsiab lus tswj tau ua rau muaj qhov sib npaug ntawm cov pa roj carbon tsawg, txo qhov kev pheej hmoo ntawm qhov txias txias hauv qhov vuam thiab cua sov- thaj tsam cuam tshuam (HAZ) thaum thiab tom qab vuam.
Versatility nyob rau hauv Vuam txheej txheem:HP295 tau tshaj txhua yam kev lag luam vuam loj, suav nrog kev siv tsis siv neeg submerged arc vuam (SAW), plasma vuam, thiab MIG / MAG vuam. Qhov no versatility ua kom siab - zoo, zoo ib yam welds uas muaj zog thiab tawv zoo li cov khoom siv hauv paus, tswj lub siab ciam teb ruaj khov.
Ua raws li cov qauv nruj:HP295 yog tsim los ua kom tau raws li cov kev cai nruj ntawm GB / T 6653, Suav teb tus qauv rau welded gas cylinder steels. Qhov kev ua raws cai no tau lees paub tias txhua pawg ntawm cov khoom siv ua raws li kev tswj hwm nruj rau cov tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab cov suab nrov sab hauv, kom ntseeg tau tias cov khoom kawg ua tau raws li kev cai thoob ntiaj teb kev nyab xeeb rau roj cia.
Tus nqi -Kev ua tau zoo:Ua ke nrog kev ua haujlwm siab nrog kev tsim khoom zoo, HP295 muaj tus nqi tshwj xeeb -kev ua tau zoo piv. Nws muab qhov tsim nyog kev nyab xeeb thiab kav ntev yam tsis muaj tus nqi them nqi siab dua - alloy steels, ua rau nws qhov kev xaiv zoo tshaj plaws rau cov khoom loj - tsim, siab - roj thooj voos kheej kheej.
| Qhov xwm txheej | HP295 kev ua haujlwm |
|---|---|
| Crack rhiab heev | Tsawg |
| Vuam efficiency | Siab |
| Kev sib koom ua ke | Zoo heev |
