Duplex Stainless tus account nyiaj rau> 80% ntawm kev noj ntawm duplex, super duplex thiab hyper duplex cov qib. Tsim nyob rau xyoo 1930 rau kev thov hauv ntawv thiab pulp ua khoom siv, alloys ua kom raws li 22% kev sib xyaw ua ke thiab cov microstritic microstructure uas tau muab cov khoom siv uas xav tau.
Piv nrog rau cov generic 304/316 Austenitic Stainless hlau, tsev neeg ntawm cov qhab nia ntawm lub zog ntau npaum li cas ib zaug thiab muab cov khoom siv tseem ceeb hauv corrosion tsis kam. Nce cov ntsiab lus chromium ntawm stainless hlau yuav nce lawv pitting corrosion tsis kam. Txawm li cas los xij, qhov pitting tiv taus tus lej (pren) uas infers ib alloys kuj tseem ua rau pitting corrosion kuj suav nrog lwm yam ntawm lwm cov qauv. Qhov no subtlety tuaj yeem siv los piav qhia txog qhov sib txawv ntawm qhov sib txawv ntawm kev sib txawv ntawm kev ua haujlwm s31803 thiab tsis tau tsim thiab seb nws muaj teeb meem.
Ua raws li kev txhim kho ntawm duplex stainless hlau, lawv thawj qhov kev tshawb fawb tau raug ntes raws li UNSENT S31803. Txawm li cas los xij, ib tus lej ntawm cov thawj coj ua lag luam tau tsim cov qib no mus rau sab saud ntawm kev tso cai tshwj xeeb. Qhov no xav txog lawv txoj kev xav kom ua kom tiav ntawm cov kev ua yeeb yam corrosion, pab los ntawm kev txhim kho ntawm Alod steel txheej txheem uas tso cai rau kev tswj hwm kev sib xyaw. Tsis tas li ntawd, nws tseem tso cai rau theem ntawm nitrogen ntxiv rau kom muaj kev cuam tshuam, ntau dua li tam sim no raws li lub keeb kwm yav dhau. Yog li ntawd, cov neeg siab tshaj plaws ua kom tiav qib siab ntawm cov chromium (CR), Molybdenum (mo) thiab nitrogen (n). Qhov sib txawv ntawm ib qho duplex uas muaj ntau yam ua tau raws li cov lus qhia hauv qab, tiv thaiv ib qho ntawm tus Prenula Pren =% CR + 3.3% MO + 16% N.
Txhawm rau sib txawv ntawm cov hlwv me me ua rau sab saum toj kawg ntawm cov muaj ntau yam, ib qho kev qhia ntxiv tau ua tiav, yog UNF32205. Duplex Stainless hlau ua rau S32205 (F60) yuav ua tau raws li S31803 (F51) LINTION, whereas qhov thim rov qab tsis muaj tseeb. Yog li S32205 tuaj yeem ua tau dual-ntawv pov thawj raws li S31803.

Sakysteel stock muaj ntau ntau ntawm cov hlwv uas tsis muaj zog ntawm tus khub uas nyiam tshaj plaws ntawm Sandvik. Peb npaj cov khoom siv ntau thiab tsawg ntawm 5/8 "txog 18" txoj kab uas hla nyob hauv Sanmac® 2205 qib, uas ntxiv 'txhim kho' rau lwm yam khoom. Tsis tas li ntawd, peb kuj npaj ntau ntawm S32205 Hollow bar los ntawm peb lub tsev muag khoom UK, thiab phaj txog 3 "los ntawm peb Portland, Tebchaws USA Warehouse.
