Vim li cas koj thiaj yuav tsum xaiv S31254?
S31254 stainless hlau Corrosion kuj
- Ib puag ncig chloride:6% molybdenum + 0.2% nitrogen tsim cov zaj duab xis tuab, thiab pitting kuj yog 10 npaug ntawm 316L. Txhua xyoo corrosion tus nqi hauv 10,000ppm chloride ion tov yog<0.01mm (316L>1 hli).
- Complex media:resistant rau hydrofluoric acid (HF), fluorosilicic acid (H₂SiF₄) thiab sib xyaw halides, npog muaj zog acid tej yam kev mob xws li tshuaj lom neeg kev lag luam thiab flue gas desulfurization (FGD).
stainless hlau 254smo Mechanical thiab lub cev muaj zog
- High zog thiab toughness ua ke:annealed yield zog Ntau dua los yog sib npaug rau 310MPa, tensile zog Ntau dua los yog sib npaug rau 650MPa, elongation Ntau dua los yog sib npaug rau 40%, zoo dua li cov tsoos austenitic steel (xws li 304 yield zog tsuas yog 205MPa).
- Tsis yog -magnetic + low temperature toughness:Sib nqus permeability Tsawg dua lossis sib npaug li 1.001, haum rau cov khoom siv hluav taws xob sib nqus resonance, -196℃cuam tshuam toughness＞100J, ua tau raws li qhov xav tau ntawm LNG cia tso tsheb hlau luam.
UNS S31254 steel phaj nqi kom zoo dua
Txawm hais tias tus nqi ntawm chav tsev yog 2.5 npaug ntawm 316L phaj, lub neej voj voog tus nqi raug txo los ntawm 52% nyob rau hauv seawater desalination system (txo hloov zaus thiab downtime poob).

Cov txiaj ntsig zoo ntawm kev siv 254 ss smo Sheet
stainless hlau 254 smKev pab lub neej ntev, kev txuag nyiaj txiag
S31254 daim ntawv yog tsim los kom kav ntev txawm nyob rau hauv ib puag ncig hnyav, radically txo cov peev txheej siv. Qhov no yog vim hais tias cov alloy lub siab yield zog (Ntau tshaj los yog sib npaug zos rau 550 MPa) enables thinner gauges tsis muaj kev cuam tshuam kev ua tau zoo, thiab txhim kho cov khoom efficiency.
254 smo steel Txo carbon hneev taw los ntawm kev tsim lub neej
S31254 ua rau qis emissions los ntawm ntau lawm thiab daim ntawv thov dua lwm yam ntaub ntawv. Nws 92% recyclability (ntau dua li polymer composites '20%) thiab ntau dua los yog sib npaug rau 75% recycled cov ntsiab lus txo CO2 emissions ib kg ntawm cov khoom los ntawm 74% piv rau cov khoom nkauj xwb.
Stainless hlau 1.4547 Kev lag luam vaj huam sib luag
Lub siab nickel thiab molybdenum cov ntsiab lus khaws cov khoom seem siab tshaj 60% ntawm tus nqi pib, piv rau tsuas yog 30% rau tus qauv 304 stainless hlau. Qhov no ua rau nws recyclable. Cov hlau nplaum ruaj khov microstructure tso cai rau kev tsim cov khoom seem rov qab siv dua rau cov khoom qis qis xws li gaskets lossis brackets.
cov ntaub ntawv s31254 Kev ua haujlwm eco-efficiency
S31254 txhim kho lub zog ua haujlwm hauv kev siv thermal. Nrog rau cov thermal conductivity ntawm 15 W / m·K, 12-18% siab dua cov hlau duplex, cov khoom siv hluav taws xob ua los ntawm S31254 phaj tuaj yeem txo cov pa thiab roj noj hauv cov txheej txheem tshuaj.
ultra 254 smo Kev tswj hwm kev ua raws cai thiab yav tom ntej-Kev pov thawj
S31254 ua raws li cov txheej txheem kev ruaj ntseg, suav nrog EU REACH, RoHS, thiab EN 10088-1 Ecodesign cov cai. Nws tau suav nrog hauv ASME Sustainable Pressure Equipment Green Materials Database, kom ntseeg tau tias ua raws li kev hloov pauv cov pa roj carbon emissions.
Daim ntawv thov ntawm ss 254smo ntawv
- Roj thiab roj:submarine pipelines, downhole cov cuab yeej rau acid gas qhov dej.
- Cov khoom siv tshuaj:sulfuric acid reactors, phosphoric acid evaporators, pickling khoom.
