1.4501 Stainless hlau yog dab tsi?

1.4501 stainless hlau, dav paub los ntawm nws lub npe lag luam Zeron 100 (thiab kuj yog UNS S32760 lossis F55), yog super duplex stainless hlau txhim kho nrog tungsten thiab tooj liab. Nws sawv cev rau lub siab tshaj plaws echelon ntawm duplex alloys, muab kev sib xyaw ua ke ntawm lub zog loj heev, tshwj xeeb tshaj yog corrosion resistance-tshwj xeeb tshaj yog tiv thaiv pitting thiab kev nyuaj siab corrosion cracking-thiab txhim kho weldability, ua rau nws yog qhov kev xaiv kawg rau kev txhoj puab heev offshore, tshuaj, thiab subsea ib puag ncig.

 

Qhov hwm super duplex qib no tau txhais raws li cov qauv tseem ceeb thoob ntiaj teb.

Txuj	Qib sib npaug
EN (Tebchaws Europe)	1.4501
ASTM / AISI (USA)	F55, UNS S32760 (Zero 100)
Lub Npe	Zeron 100

Nws cov kev ua tau zoo tshaj yog ua tiav los ntawm qhov siab, sib npaug ntawm cov ntsiab lus xws li tungsten thiab tooj liab.

Element	C	Si	Mn	P	S	Cr	Ni	Mo	N	W	Cu
Cov ntsiab lus (%)	≤ 0.03	≤ 1.0	≤ 1.0	≤ 0.03	≤ 0.01	24.0 - 26.0	6.0 - 8.0	3.0 - 4.0	0.20 - 0.30	0.50 - 1.00	0.50 - 1.00

Nws muab lub zog thiab toughness, txawm nyob rau hauv cov xwm txheej hnyav.

Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4501 / Zeron 100

Tsis sib haum Corrosion Resistance:Muaj tus lej tshwj xeeb siab Pitting Resistance Equivalent Number (PREN> 40), muab qhov zoo tshaj plaws - hauv -chav kawm tiv thaiv pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg hauv kub, chloride-laden ib puag ncig.

Muaj zog heev:Muab lub zog tawm los kwv yees li ob npaug ntawm cov qauv austenitic steels, ua kom muaj qhov hnyav thiab txo nqi hauv cov hlab ntsha siab thiab cov khoom siv.

Txhim kho Weldability:Qhov sib npaug sib npaug, suav nrog tungsten thiab tooj liab, txhawb kev ruaj khov microstructure hauv welds, ua rau nws zam ntau dua rau vuam dua li lwm cov qib super duplex.

 

Cov ntawv thov tseem ceeb:

Subsea & Offshore:Christmas ntoo, manifolds, flowlines, thiab umbilicals nyob rau hauv dej tob thiab roj ntau lawm.

Tshuaj & Txheej Txheem:Reactors, kem, thiab cov khoom siv hluav taws xob ua kom muaj zog sib xyaw ntawm cov kua qaub, chlorides, thiab lwm yam xov xwm corrosive.

Pollution Control:FGD scrubbers, absorber towers, thiab tseem ceeb ductwork.

Pulp & Ntawv:Siab -siab thiab siab - kub diesters.

 

Zeron 100 (1.4501) txawv ntawm Super Duplex 2507 (1.4410) li cas?
Thaum ob qho tib si yog qib super duplex, Zeron 100 muaj cov ntsiab lus alloying ntxiv -tungsten (W) thiab tooj liab (Cu). Tungsten ntxiv txhim kho pitting thiab crevice corrosion kuj, tshwj xeeb tshaj yog nyob rau hauv siab kub, thiab txhim kho stability ntawm lub microstructure thaum vuam. Tooj liab txhim khu kev tiv thaiv kom tsis txhob muaj cov kua qaub xws li sulfuric acid. Qhov no muab Zeron 100 qhov kev ua tau zoo nyob rau hauv qhov nyuaj tshaj plaws thiab hnyav corrosive ib puag ncig, tshwj xeeb tshaj yog cov uas muaj chlorides thiab acids.

 

Dab tsi ua rau vuam Zeron 100 txawv ntawm vuam txheej txheem duplex steels?
Vuam Zeron 100 ua raws li cov hauv paus ntsiab lus zoo sib xws (tswj cov khoom siv hluav taws xob, siv ntau tshaj -alloyed muab tub lim) tab sis tau txais txiaj ntsig los ntawm nws cov khoom zoo. Cov ntsiab lus tungsten pab tiv thaiv kev tsim cov theem cuam tshuam ntawm intermetallic nyob rau hauv tshav kub- cuam tshuam cheeb tsam (HAZ), muab qhov dav "ua qhov rai" thiab txo qhov kev pheej hmoo ntawm embrittlement. Nws tseem yuav tsum tau ua tib zoo saib xyuas cov txheej txheem tsim nyog tab sis feem ntau suav hais tias muaj qhov zoo dua weldability dua li lwm cov super duplex alloys uas zoo sib xws corrosion kuj.
