Lus Teb luv luv
ASTM A105 yog carbon hlau, tsis yog stainless hlau. A105 yog ib qho kev qhia tshwj xeeb rau carbon steel forgings rau kev siv cov kav dej, npog lub siab - muaj cov khoom xws li li qub, flanges, forged fittings thiab cov khoom zoo sib xws. Nws tsis muaj chromium ntxiv nyob rau theem uas yuav tsum tau rau stainless hlau, yog li nws tsim ib tug ib txwm hlau oxide nto es tsis txhob ntawm nyias passive chromium oxide txheej uas muab stainless hlau nws corrosion kuj.
Dab tsi ASTM A105 Tiag npog
Lub Scope ntawm A105 yog forged carbon steel qhov chaw rau ambient thiab siab kub kev pab cuam. Cov khoom uas muaj xws li flanges, forged fittings, valve lub cev, lub kaus mom thiab lwm yam siab - khaws cov khoom uas zoo li lub forging es tsis yog dov los yog casting. Vim hais tias ib feem yog forged, cov specification hais txog forging xyaum, kev kho cua sov, tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm cov khoom tiav es tsis yog nrog cov raj qhov ntev.
Cov qib yog ib txwm muab raws li -forged, lossis normalised, thiab, thaum daim ntawv xaj yuav xav tau, normalized thiab tempered. Hardness feem ntau tau teev nrog qhov siab tshaj plaws ntawm 187 HBW rau qhov ua tiav, thiab NACE ntxiv -txog kev txwv hardness tuaj yeem siv rau hauv kev pabcuam qaub.
A105 Piv nrog A106 thiab A672
Peb qhov kev qhia tshwj xeeb feem ntau tsis meej pem vim tias tag nrho peb yog carbon steel, tab sis lawv npog cov khoom sib txawv thiab ntau txoj kev tsim khoom.
| Specification | Yam khoom | Lub hom phiaj kev pabcuam |
|---|---|---|
| ASTM A105 1 | Forgings rau piping Cheebtsam | Valves, flanges, fittings thiab lwm yam siab -muaj cov khoom |
| ASTM A106 1 | Seamless carbon steel yeeb nkab | Siab - qhov kub thiab txias kev pab cuam nqa dej, roj thiab roj |
| ASTM A672 Cov Lus Qhia Tshwj Xeeb | Hluav taws xob-fusion-welded yeeb nkab | Kev pabcuam kub nruab nrab, ua los ntawm cov hlab ntsha siab zoo nrog cov hlau muab tub lim |
Vim tias cov ntaub ntawv khoom sib txawv, cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab thiab kev kho cua sov yuav txawv. A105 forgings thiab A106 yeeb nkab yog li ntawd tsis ncaj qha interchangeable yam tsis muaj kev ntsuam xyuas engineering ntawm kev sib dhos tiav. A672 welded yeeb nkab tuaj yeem ua haujlwm siab - lub luag haujlwm siab ib yam, tab sis nws yog tsom rau qhov kev pabcuam kub nruab nrab thiab tuaj yeem muab tau rau hauv ntau qhov kev kho cua sov.
Chemistry: Vim li cas A105 Tsis Stainless
| Element | Yam yuav tsum tau muaj,% |
|---|---|
| Cov pa roj carbon (C) | 0.35 max |
| Manganese (Mn) | 0.60 - 1.05 |
| Phosphorus (P) | 0.035 max |
| Sulfur (S) | 0.040 max |
| Silicon (Si) | 0.10 - 0.35 |
| Chromium (Cr) | Tsis tau teev raws li kev sib ntxiv alloying |
Stainless hlau xav tau kwv yees li 10.5% chromium raws li qhov tsawg kawg nkaus los tsim cov yeeb yaj kiab ruaj khov. A105 tsis muaj chromium alloying yuav tsum tau txhua, yog li nws tsis tuaj yeem coj raws li cov khoom siv stainless hauv ntub, chloride-cov kabmob lossis cov kua qaub ib puag ncig. Nws cia siab rau cov txheej txheej, cov ntaub hauv ob sab phlu lossis kev tiv thaiv corrosion rau kev tiv thaiv xwb.
Mechanical Behavior thiab Service Limits
Lub zog:A105 yog ib qho nruab nrab -lub zog carbon steel rau ambient thiab elevated kub piping Cheebtsam, tsis yog ib tug siab -strength low-alloy qib.
Toughness:txaus rau kev pabcuam kav dej; qis- qhov kev pabcuam kub yuav tsum muaj qhov tshwj xeeb sib txawv nrog rau kev ntsuas qhov cuam tshuam.
Corrosion:carbon steel tus cwj pwm. Hauv cov kev pabcuam ntub dej lossis txhoj puab heev, kev tiv thaiv corrosion, sab hauv hauv ob sab phlu lossis hloov mus rau qib alloy lossis stainless qib yuav tsum tau ua.
Vuam:yooj yim weldable rau cov yeeb nkab ntawm qib sib piv siv cov txheej txheem carbon steel, nrog preheat txiav txim los ntawm phab ntsa tuab.
Kub:npaj rau kev pabcuam ambient thiab siab dua; Cov dej kub uas tsis tshua muaj dej poob sab nraum nws qhov kev ua haujlwm.
Kev Taw Qhia Xaiv Tswv Yim
Xaiv A105 thaum qhov kev tivthaiv yog ib qho forging xws li flange, valve lub cev lossis haum thiab cov kev pabcuam yog carbon steel tau tshaj. Xaiv A106 thaum qhov yuav tsum tau muaj yog seamless yeeb nkab rau siab -kub dej kev pab cuam. Xaiv A672 thaum welded yeeb nkab ua los ntawm phaj nrog ntxiv muab tub lim hlau yog siv tau rau lub luag haujlwm kub kub. Yog hais tias qhov nruab nrab yog corrosive, yog chlorides tam sim no, los yog yog hais tias qhov kev khiav hauj lwm kub yog tsawg heev, tshuaj xyuas cov khoom xaiv thiab xav txog stainless los yog alloy qib es tsis txhob carbon hlau.
Thaum txiav txim, hais cov specification thiab qib raws nraim li sau nyob rau hauv tus qauv, nrog rau cov kev kho cua sov, hardness txwv thiab lwm yam kev kuaj ntxiv. Kev muab cov qhab nias kom raug zam qhov kev hloov pauv ntau yam yuam kev uas tshwm sim thaum forged thiab tubular carbon steel cov khoom raug kho raws li kev hloov pauv.

A106 yog seamless yeeb nkab thiab A672 yog hluav taws xob - fusion- welded yeeb nkab ua los ntawm lub siab lub nkoj phaj nrog muab tub lim hlau, tsom rau kev pabcuam kub.
Q: A105 puas tuaj yeem siv rau qhov kub thiab txias?
Nws yog npaj rau ambient thiab siab dua kev pab cuam; cov kev txwv tso cai ntawm cov qauv tsim qauv yuav tsum raug kuaj xyuas rau txhua daim ntawv thov.
Q: A105 tiv thaiv corrosion li cas?
Los ntawm kev tiv thaiv corrosion, coatings, hauv ob sab phlu los yog ib qho kev hloov ntawm cov khoom, vim cov hlau tsis muaj chromium zaj duab xis passive.
