Product & Process Analysis
Kev tsim khoom ntawm Super Duplex Stainless Steel Castings (xws li Qib 2507 / F53) yuav tsum tau tswj cov txheej txheem nruj heev vim nws txoj kev nyuaj dual -theem microstructure. Cov txheej txheem pib nrog Advanced Investment Casting (Silica Sol), siv high- pwm precision kom ua tiav nyob ze -net- cov khoom zoo. Thaum lub sij hawm melting theem, meej spectrochemical tswj yog yuav tsum tau tswj qhov tseem ceeb tshuav nyiaj li cas ntawm Chromium, Nickel, Molybdenum, thiab Nitrogen, kom ntseeg tau ib tug Pitting Resistance Equivalent Number (PREN) saum toj no 40.
Ib theem tseem ceeb yog Txoj Kev Kho Kho Thaum Tshav Kub Kub, feem ntau ua ntawm 1050℃thiab 1150 degree, ua raws li dej nrawm. Qhov no yog qhov tseem ceeb los tiv thaiv kev tsim cov theem ntawm kev puas tsuaj, xws li nkig Sigma (σ) theem, uas tuaj yeem cuam tshuam ob qho tib si toughness thiab corrosion kuj. Tom qab kev kho cua sov, ntau-axis CNC machining yog ua haujlwm los tswj cov khoom siv ua haujlwm siab- cov nqi hardening thiab ua tiav cov kev kam rau siab. Thaum kawg, qhov kev ncaj ncees ntawm cov casting raug txheeb xyuas los ntawm kev kuaj nruj, suav nrog ASTM A923 Method A/C corrosion tests, ferrite-scope theem kev txheeb xyuas, thiab tsis yog-kev ntsuam xyuas kev puas tsuaj (NDT) zoo li Radiographic (RT) thiab Dye Penetrant Inspection (DPI), muaj peev xwm ua kom muaj kev tiv thaiv ib puag ncig.
FAQ
Q1: Dab tsi ua rau Super Duplex stainless hlau zoo dua rau tus qauv Duplex 2205?
A: Super Duplex (piv txwv li, Qib 2507) muaj ntau dua Chromium, Molybdenum, thiab Nitrogen. Qhov no ua rau Pitting Resistance Equivalent Number (PREN) tshaj 40, muab kev tiv thaiv zoo dua tiv thaiv hauv zos pitting thiab crevice corrosion nyob rau hauv siab -chloride ib puag ncig piv rau 2205.
Q2: Koj ua li cas kom ntseeg tau qhov tseeb 50: 50 theem sib npaug?
A: Cov ferrite-rau- austenite piv yog qhov tseem ceeb. Peb ua tiav qhov no los ntawm kev tswj cov tshuaj muaj pes tsawg leeg thaum lub sij hawm melting thiab tshwj xeeb kev daws annealing ua raws li dej ceev ceev quenching. Txhua batch raug kuaj xyuas siv Ferritscope kuaj thiab kuaj metallographic.
Q3: Puas muaj kev pheej hmoo ntawm Sigma theem tsim thaum lub sij hawm casting?
A: Yog, Super Duplex rhiab heev rau nkig intermetallic theem zoo li Sigma (σ). Peb tshem tawm qhov kev pheej hmoo no los ntawm kev tswj hwm tus nqi txias txias tom qab-casting thiab siv cov kev kho cua sov tshwj xeeb los xyuas kom meej qhov siab tshaj plaws ntawm qhov tawv thiab corrosion kuj.
Q4: Cov castings puas tuaj yeem siv rau hauv cov pa roj qaub (H2S) ib puag ncig?
A: Yog lawm. Peb cov castings tuaj yeem tsim ua raws li NACE MR0175 / ISO 15156 tus qauv, ua rau lawv tsim nyog rau cov kev pabcuam qaub hauv cov roj thiab roj siv uas tiv thaiv sulfide kev nyuaj siab tawg yog qhov yuav tsum tau ua.
Q5: Kev sim ua dab tsi los xyuas qhov tseeb ntawm cov khoom?
A: Ntxiv rau cov qauv tensile thiab hardness tests, peb ua ASTM A923 corrosion tests, Charpy impact testing at sub-zero temperatures, and comprehensive NDT (X-}ray, Ultrasonic, and Dye Penetrant) kom ntseeg tau tias tsis muaj qhov tsis xws luag.
