Precipitation Hardening Stainless hlau

Lub zog siab thiab zoo toughness tuaj yeem ua tiav los ntawm kev kho cov laus, ua rau nws feem ntau siv rau hauv siab - lub zog ntawm qhov chaw.

1. 304 Stainless hlau

Ib qho ntawm cov feem ntau cov austenitic stainless hlau, nws muaj zoo heev corrosion kuj thiab machinability, ua rau nws haum rau milling 304 stainless hlau thiab CNC milling stainless hlau.

Nws yog feem ntau siv hauv kev tsim cov cuab yeej vaj tsev, khoom noj khoom haus, cov kav dej kua qaub, thiab cov khoom siv kho kom zoo nkauj.

2. 316 Stainless hlau

Qhov sib ntxiv ntawm molybdenum rau 304 txhim kho nws qhov kev tiv thaiv rau pitting thiab chloride corrosion, ua rau nws yog ib qho khoom siv rau kev siv hauv marine ib puag ncig lossis cov khoom siv tshuaj.

Milling 316 stainless hlau ua kom muaj corrosion ntau dua- cov khoom tiv thaiv, xws li cov twj tso kua mis valve lub cev thiab cov pa hluav taws kub exchanger tube nplooj ntawv.

3. 317 Stainless hlau

Raws li 316L, nws nta ntxiv molybdenum thiab chromium cov ntsiab lus, muab ntau dua corrosion kuj. Nws yog tsim rau CNC milling stainless hlau qhov chaw raug cov organic acids los yog kub kub.

4. 321 Stainless hlau

Stabilized los ntawm kev sib ntxiv ntawm titanium, nws muaj kev tiv thaiv zoo heev rau intergranular corrosion thiab haum rau stainless hlau CNC machining qhov chaw rau siab -kub pipelines thiab cov khoom siv hluav taws xob.

5. 347 Stainless hlau

Los ntawm kev ntxiv niobium los txhim kho nws cov kev tiv thaiv rau intergranular corrosion, nws tswj zoo txhua yam muaj zog txawm tias nyob rau hauv qhov kub thiab txias, ua rau cov khoom siv thermal thiab petrochemical kev lag luam.

6. 904L Stainless Hlau

Super- austenitic stainless hlau nrog cov nickel thiab molybdenum siab, nws pom zoo corrosion kuj zoo nyob rau hauv cov acid muaj zog.

Nws yog feem ntau siv nyob rau hauv stainless hlau dov mills, chemical khoom, thiab CNC machining ntawm marine Cheebtsam.

Alloying Element Cov ntsiab lus

Cov ntsiab lus chromium ntau tshaj 10.5% tsim cov zaj duab xis passive ntawm steel nto, txhim kho corrosion kuj. Cov khoom xws li npib tsib xee, molybdenum, thiab titanium ntxiv txhim kho oxidation tsis kam.

Smelting txheej txheem thiab purity tswj

Cov txheej txheem refining zoo tshem tawm impurities, ua kom cov qauv ntom ntom thiab ruaj khov ntawm stainless hlau CNC machining qhov chaw.

Ib puag ncig tej yam kev mob
Cov xeb tsis tshua muaj tshwm sim hauv qhov cua, qhov chaw qhuav. Txawm li cas los xij, nyob rau hauv ib puag ncig uas muaj cov av noo siab, acidic lossis alkaline gases, lossis ib puag ncig marine, siab dua -qib stainless hlau cov ntaub ntawv xws li 316 lossis 904L yog xav tau.

1. Kev Siv Tshuaj

Repassivate saum npoo siv cov kua qaub pickling muab tshuaj txhuam los yog tshuaj tsuag los tsim cov tshuaj tiv thaiv chromium oxide zaj duab xis. Tom qab kev kho mob, yaug nrog dej huv thiab txhuam thiab kaw.

2. Mechanical Method

Tshem tawm cov kab mob saum npoo av uas siv cov txheej txheem xws li sandblasting, txhuam hniav, thiab ceramic txhaj tshuaj blasting. Rau stainless hlau CNC qhov chaw, wax foob lub nto tom qab txhua yam polishing los txhim kho corrosion kuj.

Nyob rau hauv precision manufacturing thiabCNC machining stainless hlau qhov chawkev lag luam, kev xaiv kom raug ntawm cov qib stainless hlau yog qhov tseem ceeb hauv kev txiav txim siab cov khoom lag luam lifespan thiab kev ua haujlwm. Los ntawm kev sib xyaw ua ke ntawm kev nkag siab tob txog cov khoom siv thiab kev ua haujlwm nrog cov txheej txheem siab heev xws li milling, tig, thiab CNC milling, precision thiab kev ntseeg siab ntawm cov khoom tiav tuaj yeem txhim kho tau zoo.

Nrog rau kev nce qib ntawm automated machining chaw thiab ntse tsim, tsim ntawm stainless hlau CNC qhov chaw yog hloov zuj zus mus rau lub zog siab dua, sib dua yuag, thiab ntau dua corrosion kuj, muab kev txhawb nqa zoo thiab ruaj khov rau kev lag luam xws li lub zog tshiab, electronics, kev kho mob, thiab aviation.
