Tseem ceeb 310S Stainless Hlau Phaj Khoom

310S stainless hlau phajyog ib lub siab -kub austenitic stainless hlau, los yog UNS S31008 los yog 1.4845, nws yog dav siv nyob rau hauv furnaces, tshav kub exchangers, thiab cov khoom siv tshuaj uas ua hauj lwm kub heev.

Hauv tsab xov xwm no, peb piav qhia qhov tseem ceeb tshaj plaws ntawm 310S stainless hlau phaj khoom.

Dab tsi yog 310S Stainless Hlau Phaj?

310S yog austenitic stainless hlau nrog siab chromium thiab nickel cov ntsiab lus. Lub "S" sawv cev rau "tsawg carbon," uas ua rau nws ruaj khov ntawm qhov kub siab tshaj li tus qauv 310. Nws khaws nws lub zog thiab tiv thaiv oxidation mus txog 1,100 degree, deb tshaj qhov txwv ntawm 304 lossis 316 stainless hlau.

Peb cov phaj yog muab nyob rau hauv thicknesses ntawm 3 hli mus rau 50 hli thiab tuaj yeem txiav mus rau txhua qhov dav lossis ntev koj xav tau.

Tshuaj muaj pes tsawg leeg ntawm 310S Stainless hlau phaj

Cov tshuaj muaj pes tsawg leeg ntawm 310S stainless hlau yog lub hauv paus rau nws cov kev ua tau zoo. Nws yog ib qho qis- carbon variant ntawm 310 stainless hlau, uas txo qhov kev pheej hmoo ntawm carbide nag lossis daus thaum vuam thiab siab - kev pabcuam kub. Lub ntsiab muaj pes tsawg leeg yog raws li nram no:

Cov ntsiab lus siab chromium muab oxidation zoo heev thiab corrosion kuj.

Cov ntsiab lus siab nickel ua kom ruaj khov ntawm cov qauv austenitic ntawm qhov kub thiab txias.

Cov ntsiab lus tsis tshua muaj carbon tsawg txo qhov kev nkag siab thiab carbide nag lossis daus, uas tuaj yeem ua rau cov welds tsis muaj zog.

Cov tshuaj muaj pes tsawg leeg no ua rau 310S stainless hlau daim hlau haum rau siab - qhov chaw kub txog li 1150℃.

Mechanical Properties

Cov cuab yeej cuab tam txhais tau li cas 310S stainless hlau daim hlau ua haujlwm nyob rau hauv kev ntxhov siab, nro, thiab siab. Cov parameter tseem ceeb muaj xws li:

Lub zog tensile siab thiab elongation ua 310S daim hlau resistant rau deformation nyob rau hauv load.

Tsawg hardness ua kom yooj yim ntawm fabrication, khoov, thiab sib sau tsis muaj cracking.

Cov khoom siv ruaj khov ntawm qhov kub siab ua rau nws zoo tagnrho rau cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov thermal oxidizers.

Thaum tshav kub kub Resistance

Ib qho txiaj ntsig tseem ceeb tshaj plaws ntawm 310S stainless hlau daim hlau yog lawv qhov ua tau zoo heev -kub tsis kam.

Kev pabcuam kub kub: mus txog 1150℃hauv oxidizing cua.

Kev pabcuam kub kub: mus txog 1035℃hauv carburizing lossis txo qhov chaw.

Kev tiv thaiv zoo heev rau scaling thiab oxidation, txawm nyob rau hauv thermal cycling tej yam kev mob.

Daim ntaub ntawv: 310S stainless hlau feem ntau yog siv rau hauv boilers, gas turbines, qhov cub Cheebtsam, rauv liners, thiab siab - kub chimneys, qhov twg lwm yam stainless hlau yuav ua tsis tau tejyam.

Corrosion Resistance

Thaum 310S muaj npe nrov rau kev ua haujlwm siab - qhov kub thiab txias, nws kuj muaj qhov zoo corrosion kuj ntawm chav tsev thiab nruab nrab kub.

General corrosion: 310S resists corrosion zoo ib yam li 304 stainless hlau nyob rau hauv feem ntau me me ib puag ncig (atmospheric, dej tshiab, dilute acids).

Oxidizing acids: Kev tiv thaiv zoo rau nitric acid thiab lwm yam tshuaj oxidizing vim muaj cov ntsiab lus chromium siab.

Txo cov kua qaub (xws li sulfuric lossis hydrochloric): Tsis zoo. Tsis txhob siv 310S nyob rau hauv muaj zog txo acids.

Chloride stress corrosion cracking (SCC): Zoo li lwm yam austenitic stainless hlau, 310S tuaj yeem tawg hauv cov tshuaj chloride kub (xws li dej hiav txwv saum 140℃F / 60 degree). Yog tias cov chlorides nyob ntawm qhov kub siab, xav txog qhov siab dua -nickel alloy.

Qhov tseem ceeb: Qhov kev tiv thaiv corrosion ntawm 310S yog qhov zoo tshaj plaws hauv kev daws teeb meem -annealed mob (ceev txias tom qab cua sov). Yog hais tias cov khoom yog maj mam txias los ntawm cov carbide nag lossis daus ntau (800-1600℃F / 425-870 degree), chromium carbides tuaj yeem tsim ntawm cov ciam teb, txo cov kev tiv thaiv corrosion.

Qhov no yog vim li cas cov ntsiab lus qis carbon (0.08% max) ntawm 310S yog qhov tseem ceeb -nws txo qhov teeb meem no.

Fabrication thiab Weldability

Vuam: 310S muaj qhov zoo tshaj plaws weldability. Nws tuaj yeem welded siv tag nrho cov txheej txheem txheem (TIG, MIG, SMAW, SAW). Siv cov khoom siv sib txuam xws li 310 lossis 309 (uas muaj cov nickel qis dua tab sis tseem muaj cov khoom zoo). Tsis xav tau preheat, thiab tom qab -weld heat treatment feem ntau tsis tsim nyog. Txawm li cas los xij, yog tias qhov siab tshaj plaws corrosion kuj yuav tsum tau nyob rau hauv ib qho kev sib koom ua ke, ib qho kev tshaj tawm -weld tov anneal (cua sov rau 1900-2050℃F / 1040-1120℃tom qab txias txias) yog pom zoo.

Kev tsim: 310S tuaj yeem txias - ua los ntawm kev khoov, dov, lossis stamping. Txawm li cas los xij, nws ua haujlwm - hardens sai - txhais tau tias nws yuav nyuaj dua thiab tsis muaj zog thaum koj tsim nws. Rau cov duab complex, intermediate annealing tej zaum yuav xav tau. Kev sib sau kub kuj tseem ua tau ntawm qhov kub ntawm 1700-2200℃F (925-1200 degree), ua raws li kev daws teeb meem annealing.

Machining: 310S nyuaj rau tshuab dua li tus qauv 304 vim nws ua haujlwm - hardens sai. Siv cov cuab yeej ntse, txiav nrawm nrawm, thiab ntau cov dej txias. Nyob rau hauv cov xwm txheej annealed, machinability yog ntsuas ntawm li 45% ntawm carbon steel.

Kev kho cua sov: 310S yog muab rau hauv cov tshuaj -annealed mob. Yog tias koj xav tau rov ua dua -anneal tom qab fabrication, kub rau 1900–2050℃F (1040–1120 degree) thiab tom qab ntawd dej quench lossis txias sai hauv huab cua. Tsis txhob qeeb- txias los ntawm cov nag lossis daus ntawm carbide.

310S vs Lwm Qib: Kev sib piv ceev

310S ntaus qhov sib npaug zoo tshaj plaws ntawm kev ua tau zoo thiab tus nqi rau feem ntau siab - daim ntawv thov kub.
