Q1: Inconel 718 alloy seamless yeeb nkab nyob rau hauv ASTM B163 yog dab tsi, thiab nws lub npe UNS yog dab tsi?
A1: Inconel 718 alloy seamless yeeb nkab nyob rau hauv ASTM B163 yog qhov siab -kev ua haujlwm nag lossis daus-nickel hardening nickel-chromium- hlau superalloy yeeb nkab. Nws lub npe UNS yog UNS N07718 (W.Nr. 2.4668), thiab nws tau tsim tshwj xeeb kom ua tau raws li qhov yuav tsum tau ua ntawm ASTM B163- tus qauv specification rau seamless npib tsib xee alloy condenser thiab tshav kub- cov raj sib hloov, kom tsim nyog rau qhov kev pabcuam siab tshaj {{14} thiab kub siab.
Q2: Cov cai tseem ceeb dab tsi ua ASTM B163 yuam rau Inconel 718 seamless yeeb nkab?
A2: ASTM B163 nruj me ntsis qhia cov tshuaj muaj pes tsawg leeg, cov khoom siv kho tshuab, qhov ntev ntev, kev kho cua sov, thiab tsis yog -kev kuaj kev puas tsuaj (NDT) ntawm Inconel 718 seamless yeeb nkab. Nws yuav tsum tau ua raws li kev txwv tsis pub muaj alloy (piv txwv li, 50.0-55.0% Ni, 17.0-21.0% Cr), yuav tsum tau kuaj hydrostatic, eddy tam sim no los yog ultrasonic soj ntsuam, thiab pov thawj ntawm tensile zog, yield zog, thiab elongation kom ntseeg tau nyob rau hauv lub tshav kub hloov lwm lub tsev thiab hnyav kev pab cuam ib puag ncig.
Q3: Dab tsi yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob thiab kev pabcuam kub ntawm cov yeeb nkab no?
A3: Feem ntau muab rau hauv kev daws teeb meem-annealed (1000–1100 degree) thiab quenched mob, Inconel 718 seamless yeeb nkab muaj cov cuab yeej zoo heev ntawm chav tsev kub: tensile lub zog ntawm 965–1250 MPa, yield zog ntawm 550–1035 MPa, 12 – elongation zoo sib npaug ntawm 10% ntawm elongation. 36–42 HRC. Nws qhov kev pabcuam kub yog los ntawm -253℃(cryogenic tej yam kev mob) mus rau +705℃(high-temperature applications), ua rau nws haum rau huab cua hloov pauv.
Q4: Vim li cas Inconel 718 seamless yeeb nkab nyiam rau kev siv tseem ceeb?
A4: Inconel 718 muaj qhov tshwj xeeb creep thiab qaug zog ntawm qhov kub siab, zoo heev corrosion kuj rau oxidizing thiab txo qhov chaw, thiab siab tiv thaiv chloride kev nyuaj siab corrosion cracking. Raws li cov yeeb nkab seamless, nws tsis muaj vuam seams, ua kom cov phab ntsa tuab tuab, siab dua qhov ua haujlwm, thiab cov ntsiab lus tsis ua haujlwm tsawg dua - tseem ceeb rau cov ntawv thov uas muaj kev ntseeg siab thiab kev pab lub neej ntev tsis yog - sib tham.
Q5: Dab tsi yog cov ntawv thov ntawm Inconel 718 ASTM B163 seamless yeeb nkab?
A5: Nws yog dav siv hauv kev lag luam uas xav tau kev ua haujlwm siab nyob rau hauv cov xwm txheej hnyav, suav nrog: cov khoom siv hluav taws xob sib hloov thiab cov condensers hauv cov chaw tsim hluav taws xob thiab cov chaw siv tshuaj, aerospace hydraulic thiab roj kab, roj turbine Cheebtsam, siab - siab tubing nyob rau hauv petrochemical nroj tsuag, nuclear zog systems, thiab offshore roj thiab cov khoom siv roj av uas tiv taus kub, siab, thiab corrosion tseem ceeb.
