FAQ
Q1: Qhov txawv ntawm C71500 thiab C70600 tooj liab npib tsib xee yog dab tsi?
C71500 (70/30) muaj zog dua thiab zoo dua yaig tsis kam tshaj C70600 (90/10).C71500 muaj 30% nickel vs 10% hauv C70600. Raws li cov ntaub ntawv kho tshuab, C71500 H02 pas nrig muaj 75 ksi tensile zog vs C70600 feem ntau 55-65 ksi. C71500 raug pom zoo rau kev nrawm nrawm thiab muaj kev puas tsuaj loj, thaum C70600 haum rau kev pabcuam qis dua. Txawm li cas los xij, C71500 kim dua - feem ntau 25-30% tus nqi siab dua.
Q2: Dab tsi ASTM cov qauv npog C71500 seamless yeeb nkab thiab raj?
ASTM B111 npog seamless condenser raj, thiab ASTM B466 npog seamless yeeb nkab.Rau ASME code daim ntawv thov, siv ASME SB111 rau raj thiab ASME SB466 rau cov yeeb nkab. Cov ntawv thov tub rog xav tau MIL-T-16420K. Lwm cov qauv siv tau suav nrog ASTM B151 (rod / bar), ASTM B171 (phaj / condenser raj), thiab ASTM B122 (daim ntawv / phaj / sawb).
Q3: Dab tsi yog qhov ceev ntawm C71500 khoom hauv lb / in³?
Qhov ceev yog 0.323 lb / in³ ntawm 68℃F (8.94 g / cm³).Siv qhov no rau kev xam qhov hnyav. Rau 1 "OD × 0.065" phab ntsa C71500 tooj liab yeeb nkab, qhov hnyav yog kwv yees li 0.65 lb ib ko taw. Rau phaj, hnyav ib square feet rau 1" tuab phaj=0.323 lb/in³ × 144 in²=46.5 lb/sq ft.
Q4: Dab tsi yog qhov machinability ntsuas ntawm 70/30 tooj liab npib tsib xee?
Machinability ntsuam xyuas yog 20 (dawb-machining tooj dag=100).Qhov no txhais tau tias C71500 kuj nyuaj rau tshuab. Rau bar Tshuag, H02 temper (ib nrab nyuaj) tshuab zoo dua annealed. Siv cov cuab yeej ntse carbide, txo qis txiav nrawm, thiab cov dej txias ntau. Rau cov khoom sib xws xws li lub cev valve, xav txog kev yuav khoom tiav machined los ntawm tus neeg muag khoom.
Q5: Cov txheej txheem vuam zoo li cas rau C71500 tooj liab yeeb nkab?
Gas shielded arc vuam (TIG/MIG), coated hlau arc vuam (MMA), taub qab vuam, seam vuam, thiab qhov chaw vuam yog txhua yam zoo heev.Oxyacetylene vuam yog zoo. Brazing thiab soldering kuj zoo heev. Rau kev pabcuam dej hiav txwv, TIG vuam nrog cov hlau tsim nyog (ERNi-7) raug pom zoo. Tsis txhob overheating vim nws tuaj yeem txo qhov kev tiv thaiv corrosion.
Q6: Lub thermal conductivity ntawm 70/30 tooj liab nickel yog dab tsi?
Thermal conductivity yog 17 Btu·ft / (sq ft·ft·hr·℃F) ntawm 68℃F.Qhov no yog kwv yees li 1/12 ntawm cov tooj liab ntshiab (C12200 ntawm ~ 223 Btu). Rau kev siv hluav taws xob sib hloov, qhov qis conductivity yuav tsum muaj thaj tsam ntau dua piv rau cov tooj liab ntshiab. Txawm li cas los xij, cov hlau nplaum zoo tshaj dej hiav txwv corrosion tsis kam thiab muaj peev xwm tiv taus siab tshaj tawm ua rau nws nyiam xaiv rau marine condensers.
Q7: Lub zog tawm ntawm C71500 annealed raj yog dab tsi?
Rau OS035 annealed raj, tensile lub zog yog 54 ksi yam tsawg kawg nkaus, tab sis lub zog tawm los tsis tau teev tseg - elongation yog 45%.Rau OS025 lub teeb annealed raj, yield zog yog 25 ksi nrog tensile zog 60 ksi. Rau phaj / ntawv / sawb hauv M20 temper, yield zog yog 20 ksi nrog tensile zog 55 ksi thiab elongation 45%.
Q8: Cov duab thiab qhov ntau thiab tsawg rau C71500 yog dab tsi?
Cov duab muaj xws li round bar (1/2 "mus rau 10-1/8" dia), phaj (3/16" mus rau 2-5/8" tuab), ntawv / strip (0.065", 0.125"), raj (3/8" rau 1" OD), yeeb nkab (1/4" mus rau 12" standard / 4 "sch / 40" ntxiv thiab hnyav fittings (xov thiab socketweld 3000 # / 6000 #), thiab flanges (slip-on, threaded, dig muag, weldneck).Kev cai txiav muaj nyob ntawm phaj saws, bar saws, txiab, thiab dej dav hlau.
Q9: Dab tsi yog qhov sib npaug European cov qauv rau C71500?
EN CW352H yog tus qauv European rau C71500 (qee qhov chaw qhia CW354H - paub meej nrog tus neeg muag khoom).DIN 2.0872 yog tus qauv German. BS 2871 CN102 yog tus qauv British. Rau cov haujlwm European, qhia EN CW352H thiab thov daim ntawv pov thawj dual (ASTM + EN) yog tias xav tau.
Q10: C71500 puas tuaj yeem tiv taus siab tshaj tawm thiab kev puas tsuaj loj?
Yog lawm, C71500 tshwj xeeb yog tsim los rau kev kub ceev thiab kev puas tsuaj rau kev kub ntxhov.Cov hlau me me ntawm cov hlau (0.4-1.0%) muab nws txawv txawv rau kev yaig thiab impingement nres. Qhov no ua rau C71500 qhov kev xaiv zoo tshaj plaws rau cov kav dej condenser, cov kav dej hiav txwv, thiab cov khoom siv hluav taws xob sib txawv uas cov dej ntws tau siab thiab kev kub ntxhov yog qhov tsis tuaj yeem zam.
