Hastelloy G-30 Sawb (ASTM B582)
Hastelloy G-30 Sawb (ASTM B582)
Hastelloy G-30 Sawb (ASTM B582) yog npib tsib xee-chromium- hlau-molybdenum- tooj liab alloy sawb nrog cov ntsiab lus siab chromium thiab ntxiv cobalt thiab tungsten. Piv rau feem ntau cov nickel-raws li thiab hlau-raws li alloys, nws pom zoo corrosion kuj nyob rau hauv kev lag luam "ntub txheej txheem" phosphoric acid daws thiab nyob rau hauv complex ib puag ncig uas muaj zog oxidizing acids (xws li nitric acid / hydrochloric acid, nitric acid / hydrofluoric acid, thiab sulfuric acid sib tov).
Grain ciam teb precipitates tsis yooj yim tsim nyob rau hauv lub tshav kub- cuam tshuam cheeb tsam, tshem tawm qhov xav tau rau post-weld tshav kub kho; nws tuaj yeem siv ncaj qha tom qab vuam.
Cov khoom tau muab rau hauv daim ntawv strip, coil, thiab ntawv ci, ua raws li ASTM B582 tus qauv, thiab muaj nyob rau hauv ib qho kev mob annealed thiab ntau yam kev kho deg.
Customized specifications thiab tus nqi siv
Customization yog txaus siab. Common parameter ranges yog raws li nram no:
Thickness:Los ntawm ultra-nyias 0.01 mm foil mus rau standard 0.1 mm–3.0 mm, kub- dov sawb mus txog 13.0 mm.
Dav:Feem ntau 5 hli - 600 hli, nrog qhov siab tshaj plaws ntawm 1000 hli.
Khoom Muag Khoom:Ntxiv rau cov mos mos, lub quarter- nyuaj, semi- nyuaj, thiab lwm cov qib hardness kuj muaj.
Qauv:Cov qauv tseem ceeb yog ASTM B582 thiab ASME SB 582.
Nqe:Raws li cov nqi lag luam, peb tus nqi siv yog $ 40 txog $ 70 ib kilogram (tus nqi yuav nce ntxiv rau qhov tshwj xeeb tshwj xeeb lossis cov uas muaj kev ua haujlwm siab dua).
Nco tseg: Cov ntaub ntawv no tsuas yog siv rau kev siv xwb; tus nqi kawg yog raws li qhov kev txiav txim. Cov ntaub ntawv yog qhov tseem ceeb thiab tsis lav. Tus neeg yuav khoom yog lub luag haujlwm rau kev txheeb xyuas lawv qhov kev thov. Cov nqi yuav raug cuam tshuam los ntawm kev hloov pauv ntawm kev lag luam thiab cov nqi pauv; peb muaj cai kho tus nqi. Thov tau txais kev pom zoo zaum kawg ua ntej muab koj daim ntawv xaj.

Nco tseg: Cov txiaj ntsig raug pom yog rau kev siv nkaus xwb. Cov khoom tiag tiag yuav txawv ntawm cov khoom loj, kev kho cua sov, thiab kev sim. Tsis siv rau specification. Tiv tauj peb kom tau txais txiaj ntsig zoo.
Manufacturing txheej txheem thiab khoom raws li txoj cai
khoom siv raws li txoj cai
G-30 sawb feem ntau yog muab nkag rau hauv lub xeev dov annealed los ua kom zoo dua cov hlau tsis muaj corrosion thiab ductility.
Kev daws annealing (cov txheej txheem kev kho cua sov tseem ceeb)
Annealing kub:1177℃(2150℃F)
Lub sijhawm tuav:Kho raws li strip thickness, 10-30 feeb (10 feeb rau thinner strips)
Txoj kev ua kom txias:Dej quenching pom zoo (cua cua txias tuaj yeem siv rau strip thickness <10mm)
Txheej txheem hom phiaj:Txhawm rau kho qhov zoo tshaj plaws corrosion kuj thiab plasticity. Cov khoom siv yuav tsum tau rov ua dua -annealed tom qab tag nrho cov txheej txheem kub los yog txias deformation ua haujlwm tseem ceeb.
Cov txheej txheem ua haujlwm kub
Cov txheej txheem ua haujlwm kub:Kub forging, kub dov, kub chim siab, kub extrusion, thiab kub sib sau yog ua tau.
Nws yog rhiab heev rau strain thiab lim tus nqi, thiab lub qhov rais kub ua hauj lwm yog nqaim. Kev txo qis qis thiab nquag rov ua dua yog pom zoo kom tsis txhob overheating lossis tawg.
Kev daws teeb meem annealing yog qhov tsim nyog tom qab ua haujlwm kub los kho cov khoom.
Cov txheej txheem ua haujlwm txias
G-30 yog ib qho nyuaj tshaj li feem ntau austenitic stainless hlau, xav tau lub zog ntau dua rau qhov txias txias; nws kuj hardens sai dua, uas yuav tsum tau ntau yam txias ua hauj lwm txheej txheem ntxiv rau nruab nrab annealing.
Nws txhawb ntau txoj hauv kev txias txias, xws li txias dov, stamping, sib sib zog nqus nqus, spinning, poob rauj txoj kev, thiab shearing.
Tej thaj chaw thov
Kev ntub dej - txheej txheem phosphoric acid ntau lawm:Qhov feem ntau daim ntawv thov. Nws qhov kev tiv thaiv corrosion yog qhov zoo tshaj rau stainless hlau thiab feem ntau nickel-raws li alloys. Feem ntau yog siv rau hauv cov khoom tseem ceeb xws li evaporators, tshav kub exchangers, tshuaj tiv thaiv tank, pipelines, thiab twj / valve.
Kev kho tshuaj thiab pickling:Siv nyob rau hauv pickling kab rau stainless hlau thiab titanium cov ntaub ntawv (pickling tank, cua sov coils, thiab lwm yam). Nws tseem tuaj yeem ua haujlwm hnyav hauv sulfuric acid rov qab, petrochemical, tshuaj tua kab, thiab chiv ntau lawm.
Kev tiv thaiv ib puag ncig thiab flue gas desulfurization (FGD):Siv rau hauv ob sab phlu ntawm qhov nqus tsev uas muaj cov tshuaj chlorides thiab fluorides siab, demisters, thiab reheaters.
Qhov tseem ceeb ntawm kev tsim khoom:Feem ntau machined rau hauv lub twj tso kua mis shafts, valve stems, agitators, thiab ntau yam fasteners uas tiv taus siab loads.
