Tus? Asme sa240 316ti phaj? Yuav muaj ntau hom chaw xws li 2b, 2d, kab ntawv plaub hau. Muaj ntau qhov sib txawv xws li kub dov thiab dov dej txias dua. Ib txhia yog txawm yas coated. Nrog lub zog siab tensile lub zog thiab tawm lub zog zoo ib yam li ntawm 316 cov khoom siv,? Alloy 316ti chev? Kuj yog siv cua sov, condensers thiab hauv boilers.

304 Stainless hlau daim hlau kuj tseem siv rau hauv kev tsim kho vaj tse, kev siv siab, khoom noj thiab haus dej haus thiab ntau dua. 304L stainless hlau phaj muaj zoo corrosion tsis kam raws li cov atmospheric uas muaj qhov kub thiab txias thiab tuaj yeem tiv thaiv qee cov kua qaub.

Peb xyuas kom paub tseeb tias xaiv freatless stainless hlau 316 \ / 316ti daim hlau thiab cov ntawv txheeb tau dhau ntawm cov neeg pab txhawb 'sab hauv lub sijhawm. Peb cov hlau stainless 316 \ / 316ti daim hlau feem ntau siv nyob rau hauv cov chaw muaj kev lag luam sib txawv thiab peb acclaimed txoj hauj lwm tseem ceeb hauv kev lag luam no. Stainless hlau 316 \ / 316l \ / 316Ti Daim Hlau & Cov Ntawv Cog Tseg muaj kev sib tw txaus thiab cov khoom siv vuam.

Qeb 316 tau raug xa mus rau raws li molybdenum uas muaj ustenitic stainless hlau alloy. Txawm hais tias feem ntau pom tias yog cov tub rog alloy, the chemistry ntawm? Astm A240 tus kheej zoo heev li qib 316L. Kev hloov pauv yooj yim hauv lawv cov ntsiab lus carbon txawv txhua yam peb lub alloys.

304 Stainless hlau phaj, muaj ntau hom stainless hlau: piv txwv li Nickel ntxiv, cov qauv Austenic ntawm cov hlau yog nyob ruaj ruaj. Tus qauv crystal ua rau cov hlau yuav luag tsis muaj hlau thiab tsawg dua nkig ntawm cov kub tsawg. Rau qhov nyuaj dua thiab lub zog, ntxiv ntau cov pa roj carbon. Nrog kev kho cua sov kom zoo, cov cuab yeej no tuaj yeem siv hauv rab chais paj, cutlery, thiab cuab yeej, ntawm lwm tus.

1.4539 phaj, oxidation tsis kam. Txawm li cas los xij, cov txheej txheem kev ruaj ntseg ntawm qib no ua rau kub hnyiab, tshwj xeeb tshaj yog tshaj li 400¡Ãc. ASTM A240 UNICS N08904 cov khoom siv tuaj yeem yog cov tshuaj thaum tshav kub kho ntawm 1090-11755555555. Kev kho cua sov yog haum rau kev ua kom tawv. 1.4539 daim ntawv yog siv hauv cov roj refining, pulp thiab cov ntawv ua lag luam, roj scrubbing nroj tsuag, thiab lwm yam.

Cov phaj steel feem ntau siv rau cov txheej txheem qauv thiab kev tsim kho, cov hlab ntsha, cov nkoj siab, cov khoom siv uas muaj caj dab, thiab cov ntawv thov tub rog. Cov qib, cov ntsiab thiab cov tsis muaj ntawm cov phaj steel kuj tseem ceeb hauv nws siv li cas.

Thaum cov ntsiab lus chromium ntawm alloy yog qis dua tsawg kawg yog 12%, piv txwv li hauv Aerospace kev lag luam, lo lus "corrosion resistant steel" yog siv. Stainless tus hlau los hauv cov qib sib txawv thiab cov npoo ua tiav, nyob ntawm seb nws siv qhov twg.

Stainless hlau yog ib qho hlau alloy muaj tsawg kawg yog 10.5% chromium. Chromium ua cov txheej txheej nyias ntawm oxide nyob rau saum npoo ntawm cov hlau, hu ua "passivation txheej".

Thaum hlau-rau-hlau hnav ntawm 304 steel phaj yog qhov teeb meem, xws li tooj dag ua ke rau cov khoom sib txawv ntawm cov hlau, lossis txawm sib txawv ntau hom stainless hlau (Martension thiab Austenite). Nitronic alloys txo cov nyiam hnav los ntawm kev xaiv ua ke nrog manganese thiab nitrogen. Ib qho ntxiv, cov pob qij txha tuaj yeem ua kom muaj lubricated los tiv thaiv kev hnav.

Qeb 304 \ / 304L stainless hlau muaj tsawg kawg 18% chromium thiab 8% npib tsib xee. Qhov sib txawv tsuas yog ntawm lawv yog cov ntsiab lus carbon. Hom 304 muaj qhov siab tshaj plaws carbon ntawm 0.07% .type 304l muaj qhov siab tshaj Carbon ntawm 0.030%. Qhov ntau ntawm cov pa roj carbon hauv cov hlau cuam tshuam rau corrosion tsis kam. 304 \ / 304L muaj nyob rau hauv ntawv, ntawv coil, phaj, phaj coil, puag ncig cov khoom lag luam rau cov khoom lag luam ntxiv.

Inconel 600 yog ib qho tshwj xeeb npib tsib xee-chromium alloy uas paub rau nws oxidation tiv taus ntawm qhov kub siab dua. Nws yog ntau yam thiab tuaj yeem siv rau txhua yam ntawm cryogenics rau cov ntawv thov uas tam sim no nce txog li 2000dÃf (1093¡Ã).

Ib lub super duplex stainless hlau yog txhais ua lub hlwv yas nrog pitting corrosion (pre)>% (% mo + + 1 x 100 n. Usually super duplex steels have a chromium content of 25% or more, some common examples are S32760 (Zeron 100), S32750 (2507) and S32550 (Ferralium), but not all Ferralium grades are super duplex steels.

HT cov yeeb nkab muaj cov cuab yeej niaj hnub nrog cov pab pawg txawj thiab cov kws tshaj lij. Peb ua kom siv cov cuab yeej siab tshaj plaws thiab nruj me ntsis ua raws li cov txheej txheem kev tsim khoom zoo. Cov ntaub ntawv qib siab no suav nrog Manganese, cov pa roj carbon, sitholog, phosphorus, sulfur, chromium, npib tsib xee, molybdenum hauv nws.

Stainless hlau 304 hlau yog resistant rau corrosion thiab staining, kev txij nkawm tsawg, feem tsawg tus nqi, thiab cov khoom siv tsawg uas ua rau nws cov khoom zoo rau ntau cov ntawv thov. Muaj ntau tshaj 150 qib ntawm stainless hlau, 15 ntawm uas yog feem ntau siv.

ASTM A240 316TI Daim phiaj yuav tsum yog ua los ntawm ib tug txheej txheem kub kub lossis txias dua los ntawm tus neeg yuav khoom. Cov hlau yuav tsum yog los ntawm hluav taws xob-arc rauv taws feem ntau yog ua raws li cov txheej txheem hluav taws xob hluav taws xob. Cov phiaj yuav tsum tau muab rau kev kho kom sov sov, uas nws yog tsau rau hauv 1900-2150 degree ntau yam ua raws los ntawm dej quench.

316ti yog qhov sib ntxiv ntawm titanium rau 316 zoo stainless hlau. Yog tias cov khoom siv tau kub los ntawm 550 txog 800 txog 800 Ã Ã c rau lub sijhawm ntev, siv 316TI (1.4571) qib stainless. 316ti stainless hlau muaj cov nyiaj tsawg ntawm titanium. Tus nqi no feem ntau yog 0.5%. 316Ti qib stainless hlau muaj lub sijhawm ntev dua 304 lossis 316 stainless hlau qib.

Alloy 904L stainless hlau phaj nyob rau hauv thicknesses los ntawm 3 \ / 16 "los ntawm 2". Alloy 904L (tsis yog n08904) yog Superaustenitic Stainless hlau tsim rau corrosion thiab pitting yeem nyob rau hauv ntau cov txheej txheem ib puag ncig.

Nyob rau hauv 304 stainless hlau phaj, ferritic stainless hlau feem ntau muaj cov khoom siv roj hluav taws xob zoo dua li cov ntsiab lus chromium thiab npib tsib xee, xeb tawm tsam yog txo. Lawv kuj yog pheej yig dua.

Cov phiaj nruab nrab thiab hnyav kav hlau xa mus rau cov phaj hlau nrog lub thickness ntau dua 3 hli thiab tsawg dua 50 hli. Nruab nrab thiab tuab cov hlau hlau feem ntau yog siv nyob rau hauv nkoj shrbuilding, boilers, choj
