ASTM A335 P5, P9, P11, P12, P22, P91, P125
Alloy Steel Seamless kav yog dav siv hauv cov roj av, kev lag luam roj ntsha, kev tsim kho hluav taws xob, kev tsim kho, kho mob, kho mob, kev tiv thaiv thiab hluav taws xob. P91 Alloy Steel yog siv nyob rau hauv kev lag luam muaj zog. Rau welded qauv, lub asme boiler thiab siab vessel code txwv cov pa roj carbon ntau dua 0.35%. Alloy cov hlau yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum muaj zog dua, ua rau muaj kev tiv thaiv hluav taws xob hlau qib.
Peb tus TI Qib 2 Flange, Carbon Steel A694 F60 F65 (TTM ARB, ASTM A182 S32750 Stad Bolt yog qhov tshiab hauv thev naus laus zis thiab tsim nyog hauv cov qauv. Lawv muag tau zoo nyob hauv tsev thiab txawv tebchaws thiab tau txais tos los ntawm cov neeg siv feem ntau. Los ntawm kev ua haujlwm zoo, peb vam tias yuav ua rau muaj kev loj hlob ua kom muaj kev loj hlob ntawm kev tswj hwm ib puag ncig thiab qhov tseem ceeb ntawm cov muaj zog tib neeg cov peev txheej. Tam sim no, peb tab tom siv zog ntxiv rau hauv qhov tshiab ib txwm, cia siab tsim kho tus qauv tshiab ntawm lub tuam txhab kev txhim kho hauv kev coj tshiab. Thaum nkag siab cov ntsiab lus tseem ceeb ntawm kev siv tshuab, lub tuam txhab them ntau dua los muab cov khoom lag luam thiab cov kev pabcuam zoo dua. Cov cuab yeej siv tau zoo heev, cov txuj ci kws tshaj lij, cov kev pab ntau lawm, kev lees paub zoo thiab raws sijhawm tau peb cov neeg siv khoom.
Lub ATTM A194 cov kev qhia tshwj xeeb yog cov tshuaj carbon, alloy, thiab martensitic stainless hlau txiv ntoo nyob rau hauv ntau thiab tsawg rau 4 nti thiab metric m6 mus rau M100 nominal. Nws tseem npog Anustenitic stainless hlau txiv ntoo hauv qhov loj ntawm 1 \ / 4 nti thiab m6 nominal thiab saum toj no. Cov txiv ntoo no yog siv rau kev pabcuam siab lossis kub kub, lossis ob qho tib si.
International Stainless Hlau Txawv Txawv Txoj Cai Lub Tebchaws Asmeskas Hlau thiab Hlau Lub Koom Haum Siv Peb Tus lej los cim ntau cov qauv ntawm cov kab mob stainless. Ntawm lawv: ¢ atausustenitic stainless hlau yog cim nrog 200 thiab 300 series cov lej. For example, some of the more common austenitic stainless steels are marked with 302, 304, 316 and 310, ¢ÚFerritic and martensitic stainless steels are used The number of the 400 series is represented. ¢ferritic stainless hlau yog cim nrog 430 thiab 446, cov xim tawv tawv me me), muaj nag lossis 4%
Raws li ib qho ntawm cov thawj coj ua lag luam hauv Suav teb, peb sov siab txais tos koj mus yuav peb 309 stainless hlau phaj ntawv kauj. Peb lub Hoobkas kuj lees txais cov kev txiav txim siab customized. Thov tsis pub muaj kev txaus siab rau peb tus nqi sib tw thiab kev pabcuam zoo.
Alloy Steel yog hlau uas tau sib xws nrog ntau yam ntawm cov ntsiab lus hauv 1.0% thiab 50% los ntawm qhov hnyav los txhim kho nws cov khoom siv. Alloy cov hlau tawg tau tawg rau ob pawg: cov hlau qis thiab cov hlau loj. Qhov sib txawv ntawm ob yog kev sib cav. Smith thiab Hashemi txhais tau qhov sib txawv ntawm 4.0%, thaum degarmo, li al., Txhais tau nws ntawm 8.0%. [1] Feem ntau, cov kab lus "alloy steel" yog hais txog tsawg-alloy steels.
Txawm hais tias ntxiv cov ntsiab no, tsawg allolo steel flanges tsis tas yuav nyuaj rau Weld. Tus yuam sij kom ua tiav qhov ua tau zoo ntawm kev ua haujlwm vuam yog los ntawm kev paub raws nraim li cov hlau tsawg-alloy koj muaj.
