ASTM A240 904L phaj tsum,tiv tauj pebkom tau txais kev tsocai dawb thiab qauv!
ASTM A{0}}L phajyog lub siab- alloy austenitic stainless hlau phaj uas yog tsim tshwj xeeb rau kev siv hauv qhov chaw corrosive. UNS N08904 lub npe qhia tias nws yog cov tsev neeg super austenitic stainless hlau. Qhov noASME SA 240 Gr 904Lmuaj kev tiv thaiv corrosion zoo heev, tshwj xeeb tshaj yog nyob rau hauv hnyav hnyav xws li cov sulfuric acid, acetic acid, thiab lwm yam corrosive.
Kev siv ntau ntawm ASME SA240 Gr 904L Phaj.
1. Kev ua tshuaj lom neeg:
ASTM A240 UNS N08904 phaj ntawv yog siv dav hauv kev ua tshuaj lom neeg vim nws zoo heev tiv thaiv corrosion nyob rau hauv ob qho tib si txo thiab oxidizing ib puag ncig. Cov904L UNS N08904 phajyog siv rau fabrication ntawm chemical cia tso tsheb hlau luam, pipelines, tshav kub exchangers, thiab lwm yam khoom uas nquag raug rau heev corrosive acid thiab alkaline daws.
2. Kev lag luam roj thiab roj:
ASME SA 240 904L Phajyog dav siv nyob rau hauv cov roj thiab roj kev lag luam vim nws zoo heev tsis kam mus ntsev dej corrosion. CovSA 240 Gr 904L phajyog siv los ua cov khoom siv hluav taws xob sib txuas, cov kav dej, cov roj thiab cov roj tso tsheb hlau luam, cov twj tso kua mis, thiab lwm yam khoom siv roj thiab roj uas raug rau cov dej hiav txwv thiab cov tshuaj corrosive.
3. Kev tsim hluav taws xob:
ASME SA 240 UNS N08904 PhajNws kuj tseem tsim nyog siv rau hauv cov cuab yeej tsim hluav taws xob vim nws zoo heev -kub tsis kam thiab oxidation tsis kam. CovAISI 904L phajyog siv los ua cov cua kub exchangers, turbines, chav thiab roj turbines, thiab lwm yam khoom siv hluav taws xob tsim hluav taws xob uas ua haujlwm ntawm qhov kub thiab txias thiab raug rau cov pa phem.
4. Desalination Nroj Tsuag:
ASME SA 240 904L UNS N08904 Phajyog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cov nroj tsuag desalination. CovEN 1.4539 stainless hlauphaj qhov zoo tshaj plaws corrosion kuj, ua ke nrog nws lub zog, ua rau nws yog ib qho kev xaiv zoo heev rau kev ua cov cua kub exchangers, evaporators, thiab lwm yam khoom siv nyob rau hauv cov txheej txheem desalination.
5. Kev ua zaub mov:
Alloy 904l stainless hlau ntawvNws kuj tseem siv rau hauv kev ua zaub mov vim nws zoo heev corrosion kuj thiab tu cev. 1.4539 904l phaj yog siv los ua cov khoom siv ua zaub mov, xws li cov nkoj ua noj, lub tank cia, thiab cov tshuab ua zaub mov, uas raug rau cov khoom noj khoom haus corrosive thiab tshuaj ntxuav.
Key Performance Advantages
Sulfuric Acid Resistance:Tsis zoo li tus qauv 316L, cov ntsiab lus tooj liab hauv 904L tso cai rau nws tawm tsam sulfuric acid nyob rau hauv tag nrho cov concentrations ntawm kub txog 35 degree.
Siab Pitting Resistance:Nrog lub siab PREN (Pitting Resistance Equivalent Number), nws ua tau zoo nyob rau hauv qhov chaw sov chloride qhov twg 316L yuav poob vim kev ntxhov siab corrosion tawg (SCC).
Tsis yog-Magnetic:Txawm tias tom qab ua haujlwm txias, 904L tseem tsis yog- sib nqus, ua rau nws zoo tagnrho rau cov tsev kho mob tshwj xeeb thiab hluav taws xob.
Fabrication, Welding, thiab Supply Norms
Tshwj xeeb Weldability
Vim nws cov qauv austenitic crystalline tag nrho,904L stainless hlau phajWeldable zoo heev siv cov qauv roj tungsten arc vuam (GTAW/TIG), roj hlau arc vuam (GMAW/MIG), thiab tiv thaiv hlau arc vuam (SMAW) txoj kev. Lub ultra- qis carbon profile tshem tawm qhov xav tau tom qab-weld heat treatment (PWHT). Tshaj -cov khoom siv sib xyaw ua ke (xws li sib piv E904L lossis ER904L cov xov hlau) xyuas kom cov vuam seam phim lub hauv paus hlau qhov corrosion kuj.
Txuj kev ua raws cai & xa tawm qauv
Dimensional Specification:ASTM A240 / ASME SA240 (Kub{2}} dov daim hlau thiab txias - cov ntawv dov)
Cov qauv xeem:100% Ultrasonic Testing (UT) ua raws li ASTM A435/A578, ua tiav nrog EN 10204 3.1 Daim Ntawv Pov Thawj Mill Test (MTR).
Hauv kev xaus,ASTM A240 UNS N08904 Phajyog ntau yam thiab siab - zoo stainless hlau phaj uas pom muaj ntau yam kev siv hauv ntau yam lag luam.N08904 stainless hlauzoo heev corrosion kuj, lub zog, thiab durability ua rau nws yog ib tug zoo tagnrho xaiv rau siv nyob rau hauv heev corrosive thiab hnyav ib puag ncig.
