Khoom Description
17-4 Stainless Hlau Square Hlau Tubes
Dab tsi yog 17-4 Stainless hlau siv rau?
Roj thiab Roj
17-4 stainless hlau yog qhov kev xaiv zoo rau kev lag luam roj thiab roj vim tias nws muaj peev xwm tiv taus cov xwm txheej hnyav thiab ib puag ncig corrosive. Cov hlau yog cov resistant rau corrosion los ntawm cov dej ntsev thiab tshuaj, ua rau nws zoo haum rau siv nyob rau hauv offshore thiab ntug dej hiav txwv ib puag ncig.
Tsis tas li ntawd, 17-4 stainless hlau muaj lub zog-rau-qhov hnyav piv, uas ua rau nws zoo tagnrho rau kev siv hauv kev lag luam roj thiab roj qhov hnyav thiab qhov loj me feem ntau yog qhov tseem ceeb.
Petrochemical
Hauv kev lag luam petrochemical, 17-4 stainless hlau feem ntau yog siv los tsim cov khoom siv, xws li cov khoom siv hluav taws xob, cov twj, thiab cov li qub.

Lub alloy tuav nws cov qauv kev ntseeg siab ntawm qhov kub thiab txias, ua rau nws tsim nyog rau kev siv hauv kev siv xws li kev tsim cov khoom siv hluav taws xob thiab lwm yam khoom siv uas siv hauv kev ua thiab kev thauj mus los ntawm petrochemicals.
Aerospace
17-4 stainless hlau tuaj yeem siv rau hauv kev tsim cov khoom siv dav hlau dav hlau, xws li turbine blades thiab rotors, nrog rau kev tsim cov cuab yeej dav hlau thiab cov khoom siv xws li tsaws iav.
Lub alloy yog zoo haum rau siv nyob rau hauv aerospace Cheebtsam uas raug rau siab loads thiab hnyav ib puag ncig, xws li qhov chaw siab tshaj thiab huab cua kub.
Kev ua zaub mov
Hauv kev lag luam ua zaub mov, corrosion-resistant 17-4 stainless hlau feem ntau yog siv rau hauv kev tsim khoom noj khoom haus, xws li cia tank, conveyors, thiab ua machinery. Cov hlau nplaum yog hlau nplaum, ua rau nws zoo tagnrho rau kev siv hauv cov khoom noj khoom haus uas cov hlau nplaum yog siv los xyuas kom meej tias cov pa phem raug tshem tawm.
Tsis tas li ntawd, lub zog siab thiab ua haujlwm ntev ntawm 17-4 stainless hlau ua rau nws zoo haum rau kev siv hauv cov ntawv thov uas yuav tsum tau ua kom huv thiab tu cov txheej txheem.
Ntawv / Pulp
Hauv kev lag luam ntawv thiab cov ntaub so ntswg, 17-4 stainless hlau yog siv thaum tsim cov khoom siv uas ua cov ntaub ntawv xws li tso tsheb hlau luam, twj, li qub, thiab cov khoom siv hluav taws xob. Vim hais tias cov khoom yuav raug kub hnyiab tau, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov hlau zoo li 17-4.

17-4 Stainless Hlau Square Hlau Tubes
17-4 stainless yog lub hnub nyoog-hardening martensitic stainless combining siab zog nrog corrosion kuj ntawm stainless hlau. Hardening yog ua tiav los ntawm ib lub sij hawm luv luv, kev kho mob tsawg-kub yooj yim. Tsis zoo li cov pa martensitic stainless hlau, xws li hom 410, 17-4 yog weldable heev. Lub zog, corrosion kuj thiab yooj yim fabrication yuav ua tau 17-4 stainless ib tug nqi-zoo hloov rau siab zog carbon steels raws li zoo raws li lwm yam stainless qib.Thaum cov tshuaj kho kub, 1900 degree F, cov hlau yog austenitic tab sis undergoes transformation. mus rau qhov qis-carbon martensitic qauv thaum lub sij hawm txias rau chav tsev kub. Qhov kev hloov pauv no tsis tiav kom txog rau thaum qhov kub poob mus rau 90 degree F. Cov cua kub tom qab mus rau qhov kub ntawm 900-1150 degree F rau ib mus rau plaub teev nag lossis daus ntxiv dag zog rau cov hlau. Qhov kev kho hardening no kuj tempers cov qauv martensitic, ua kom ductility thiab toughness.
