Stainless hlau 254 SMO Phaj Nqe

Stainless hlau 254 SMO phaj (UNS S31254 / 1.4547 / F44)yog ib qho super-austenitic stainless hlau khoom plig rau nws txoj kev tiv thaiv zoo rau pitting, crevice corrosion, thiab chloride kev ntxhov siab tawg hauv dej hiav txwv thiab cov tshuaj lom neeg ib puag ncig. Engineers xaiv nws thaum 316L lossis 904L tsis muaj zog txaus, tab sis tag nrho cov nickel alloys kim heev.

Ntawm peb lub Hoobkas tshwj xeeb hauv cov khoom lag luam stainless hlau thiab npib tsib xee alloy, peb tsim 254 SMO daim hlau txhua lub lim tiam rau ASTM A240, ASME SA240, thiab NORSOK M-630 cov qauv.

Kev nkag siab ntawm stainless hlau 254 SMO phaj nqe pab koj cov peev nyiaj kom raug thiab sib piv cov neeg muag khoom. Hauv tsab xov xwm no peb piav qhia txog tus nqi tam sim no 2026 hauv cov lus meej; tag nrho cov lej yog raws li niaj hnub no cov khoom nyoos- cov khoom lag luam thiab peb lub Hoobkas- cov lus ncaj qha.

Qhov nruab nrab 254 SMO stainless hlau phaj nqi ib kg hnub no yog li ntawm $ 11.80 txog $ 16.50, nyob ntawm thickness, kom muaj nuj nqis, thiab ntawv pov thawj. Peb ncaj qha-los ntawm-mill nqi feem ntau yog 18-28% qis dua tus nqi xa tawm vim peb tswj tag nrho cov saw hlau los ntawm melting mus rau qhov kawg dov.

Table 1: 254 SMO Phaj Nqe ib Kg los ntawm Thickness (FOB Tuam Tshoj, USD / kg)

Thickness (hli)	Tus nqi ntau (USD / kg)	Nqe rau 1-5 tons	Nqe rau 10+ tons	Siv dav
3 – 6	14.80 – 16.50	15.80	14.80	Cladding, linings, cov hlab ntsha me me
8 – 12	13.20 – 14.90	14.20	13.20	Thaum tshav kub kub exchangers, tank
15 – 20	12.50 – 13.90	13.30	12.50	Cov hlab ntsha siab, cov kav dej txhawb nqa
25 – 30	11.80 – 13.20	12.60	11.80	Offshore platforms, cov qauv hauv paus
40 – 50	12.80 – 14.50	13.70	12.80	Heavy- lub luag haujlwm reactors

Cov nqi suav nrog kev kuaj PMI, kuaj xyuas ultrasonic, thiab daim ntawv pov thawj tag nrho cov ntawv xeem (EN 10204 3.1). Rau PED lossis NORSOK cov ntaub ntawv pov thawj ntxiv $ 0.40– $ 0.70 ib kg. Daim iav polish los yog kev cai beveling ntxiv $0.50–$0.90 ib kg.

Kev txiav txim loj dua coj tus nqi qis dua ib kilogram. Ib qho -tuj mus sib hais zaum ntawm qhov kawg ntawm qhov ntau, thaum qhov kev txiav txim 20-tuj tuaj yeem txo 254 SMO phaj nqi ib kg txog li 22%. Peb kuj tseem muab cov ntawv cog lus them nqi tas mus li uas tiv thaiv koj ntawm txhua hli nickel thiab molybdenum nqe swings.

254SMO Plate Price by Quantity and Order Size

Plaub yam tseem ceeb txiav txim siab tus nqi kawg:

Cov nqi raw khoom

254 SMO muaj 6.0-7.0% molybdenum thiab 0.18-0.25% nitrogen. Thaum molybdenum nce $ 1,000 ib tuj, phaj nqi ib kg feem ntau txav los ntawm $ 0.25- $ 0.35.

Thickness thiab Rolling Complexity

Nyias daim hlau (3-6 hli) yuav tsum tau muaj meej dov hla dhau thiab nruj dua tswj zoo, nce tus nqi ib kg. Cov phaj tuab heev (tshaj li 40 hli) siv cov slabs hnyav dua thiab ua kom qeeb qeeb, thiab ntxiv cov nqi.

Quantity thiab Lead Time

Standard 4-6 lub lis piam xa khoom yog qhov kev lag luam tshaj plaws. Rush xaj (nyob rau hauv 3 lub lis piam) ntxiv $0.80–$1.20 ib kg.

Ntawv pov thawj thiab kuaj

Basic ASTM daim ntawv pov thawj yog pub dawb. Tag nrho thib peb-kev tshuaj ntsuam xyuas (SGS, BV, lossis TÜV) lossis NORSOK M-630 ntxiv $ 0.50– $ 0.80 ib kg tab sis yuav tsum tau ua rau cov haujlwm sab nrauv thiab lub nkoj siab.

Peb tus nqi yog pob tshab tag nrho: koj pom txhua tus nqi tiv thaiv ua ntej koj xaj.

Table 2: Nqe ib Kg Sib Piv (15 hli phaj, 5-tuj xaj, USD / kg)

Qib	Nqe ib kg	PREN Tus nqi	Yield zog (MPa)	Zoo tshaj rau
316L	3.20 – 3.80	24–28	170–220	Me me corrosion
904L	6.80 – 8.20	34–36	220–300	Sulfuric acid
254 SIB	12.50 – 13.90	42–46	300–400	Seawater & txhoj puab heev chlorides
Super Duplex 2507	7.80 – 9.20	40–45	550–700	Dej hiav txwv heev

254 SMO muab cov tshuaj chloride siab tshaj plaws ntawm tus nqi nruab nrab - ntau. Nws feem ntau txuag nyiaj ntau dua 10-20 xyoo vim nws xav tau yuav luag tsis muaj kev tiv thaiv corrosion thiab kav ntev dua li qis dua - cov ntaub ntawv qib.

Siv cov qauv no yooj yim:

Tag Nrho Tus Nqi=(Nqe ib kg) × (Tag nrho qhov hnyav hauv kg)

Piv txwv

Koj xav tau kaum 15 hli daim hlau, txhua 3000 hli × 1500 hli.

Luas alas=3 m × 1.5 m=4.5 m²

Luj ib m² (15 mm)=15 × 7.93=118.95 kg/m²

Nyhav ib phaj=118.95 × 4.5=535 kg

Tag nrho qhov hnyav rau 10 daim phiaj=5,350 kg

Nqe ib kg (10-tuj bracket)=$12.80

Tag nrho cov khoom raug nqi=5,350 × 12.80=$68,480

Ntxiv freight ($ 0.80 - $ 1.60 ib kg) thiab koj muaj koj tus nqi tsaws hauv feeb.
