316LSS los yog Hastelloy, cov khoom twg tiv taus kub thiab siab?
Hastelloy B-3
Hastelloy B-3 Product Overview
Hastelloy B-3 yog npib tsib xee-raws li high-temperature alloy tsim los ntawm npib tsib xee, molybdenum, cobalt thiab lwm yam ntsiab lus, nrog ib tug nickel ntsiab lus ntawm kwv yees li 65%. Hastelloy B-3 nickel-based alloy khoom yog cov khoom siv txhim kho raws li Hastelloy B-2. Nws txhim kho cov thermal stability ntawm cov khoom, yog li txhim kho corrosion kuj. Nyob rau tib lub sijhawm, nws txhim kho cov txheej txheem kub thiab txias ua haujlwm. Nyob rau hauv xyoo tas los no, nws tau siv ntau zuj zus hauv kev tsim thiab tsim cov khoom siv tshuaj.
Mechanical zog ntawm Hastelloy B-3 alloy daim ntawv nyob rau hauv cov tshuaj tov khoom:
Raws li cov cua kub kub nce, nws lub zog tensile, lub zog tawm los, thiab elastic modulus yuav txo qis, thaum lub elongation, thermal expansion coefficient, thermal conductivity, thiab cov cua kub tshwj xeeb yuav nce me ntsis; Thaum lub caij txias deformation nce, nws hardness, tensile zog, thiab tensile zog yuav txo. Lub zog thiab yield zog nce, thiab elongation txo
Hastelloy B-3 Nta
1. Cov khoom siv Hastelloy B3 muaj qhov elongation siab, tsim kom muaj kev sib haum xeeb rau kev sib sau txias.
Cov khoom siv Hastelloy B3 yog ib qho nyuaj tshaj li austenitic stainless hlau thiab muaj lub siab xav ua haujlwm hnyav dua, yog li nws yuav tsum tau ua kom muaj zog ntau dua thaum lub caij txias los yog ua cov kauj ruam.
2. Thaum lub caij txias deformation tus nqi ntawm Hastelloy B3 cov khoom yog tsawg dua 10%, nws yuav tsis cuam tshuam rau corrosion kuj ntawm lub workpiece, tab sis thaum lub sij hawm vuam txheej txheem, muaj cov residual kev nyuaj siab yuav ua rau kub tawg nyob rau hauv lub vuam. Yog li ntawd, rau cov workpieces uas yuav tsum tau welded tom qab, lub zog ntawm residual kev nyuaj siab yuav tsum tau muab tshem tawm kom ntau li ntau tau.
3. Cov txheej txheem txias nrog qhov deformation hnyav yuav ua rau kom cov txiaj ntsig zoo ntawm Hastelloy B3 cov khoom thiab ua rau muaj kev cuam tshuam rau kev ntxhov siab corrosion thiab tawg. Cov txheej txheem kev kho cua sov nruab nrab thiab zaum kawg feem ntau yog siv.
4. Hastelloy B3 cov khoom yog rhiab heev rau oxidizing xov xwm thiab leej faj, phosphorus, txhuas thiab lwm yam tsawg melting point hlau nyob rau hauv high kub.
Hastelloy B-3 Thermal Stability
Piv nrog rau Hastelloy B-2 alloy, qhov zoo tshaj plaws ntawm B-3 alloy yog tias nws tseem tuaj yeem tuav tau zoo heev thaum raug kub kub rau ib lub sijhawm luv luv. Qhov kev raug mob no feem ntau tshwm sim tsis tu ncua thaum kho cua sov ntawm cov txheej txheem. B-2 alloy yog qhov cuam tshuam rau embrittlement thaum raug kub ntawm 700 degree rau lub sijhawm luv luv, thaum B-3 alloy muaj qhov cuam tshuam loj heev rau embrittlement thiab tuaj yeem muaj sia nyob tau ntev li ob peb teev. Qhov no muab kev yooj yim zoo rau cov alloy los tsim rau hauv cov khoom sib xws xws li kev tsim cov khoom siv.
Hastelloy B-2 thaj chaw thov
Hastelloy B-3 alloy tuaj yeem siv rau hauv txhua daim ntawv thov ntawm B-2 alloy. Zoo li B-2 kub, B-3 tsis pom zoo siv nyob rau hauv ib puag ncig uas ferric hlau ntsev thiab divalent tooj liab ntsev nyob, vim tias cov ntsev no yuav ua rau corrosion sai. Thaum hydrochloric acid los rau hauv kev sib cuag nrog hlau thiab tooj liab, nws reacts chemically tsim ferric hlau ntsev thiab divalent tooj liab ntsev.
