317L(1.4438) iPropati ngokuBanzi
I-alloy 317LMN kunye ne-317L yi-molybdenum-ethwele i-austenitic stainless steel ityhubhu enokwanda kakhulu kokuchasana nokuhlaselwa kweekhemikhali xa kuthelekiswa nombhobho oqhelekileyo we-chromium-nickel austenitic steel stainless steel onjenge-Alloy 304. Ukongeza, i-317LMN kunye ne-317L i-alloys inikezela ngokunyuka okuphezulu -ukuqhekeka, kunye namandla okuqina kumaqondo obushushu aphakamileyo kunezintsimbi eziqhelekileyo ezingenasici. Zonke iikhabhoni eziphantsi okanye "L" amabakala ukubonelela ukuxhathisa ukwazisa ngexesha le-welding kunye nezinye iinkqubo ze-thermal.
Izibizo zika-"M" kunye no-"N" zibonisa ukuba iingoma zinemigangatho eyongeziweyo yemolybdenum kunye nenitrogen ngokulandelelanayo. Indibaniselwano ye-molybdenum kunye ne-nitrogen isebenza ngokukodwa ekwandiseni ukuxhathisa kwimingxuma kunye nokuhlwa kwemingxuma, ngakumbi kwiinkqubo zemisinga equlethe i-asidi, i-chlorides, kunye neekhompawundi zesulfure kumaqondo obushushu aphezulu. I-Nitrogen ikwasebenza ekwandiseni amandla ezi ngxubevange. Zombini ii-alloys zenzelwe iimeko zenkonzo ezinzima ezifana neenkqubo ze-flue gas desulfurization (FGD).
Ukongeza kwizinto ezigqwesileyo zokuxhathisa umhlwa kunye neempawu zokomelela, ii-alloys 316, 316L, kunye ne-317L Cr-Ni-Mo ialloys zikwabonelela ngokugqwesa okugqwesileyo kunye nokwakheka okuqhelekileyo kwe-austenitic stainless steel tubing.
317L (1.4438) Unyango lokutshisaUkuhlaziya
Umbhobho we-austenitic stainless steel inikezelwa kwimeko yokusila elungele ukusetyenziswa. Unyango lobushushu lunokuba yimfuneko ngexesha okanye emva kokwenziwa ukuze kususwe iziphumo zokuyila okubandayo okanye ukunyibilikisa i-chromium carbides egayiweyo ngenxa yokuvezwa kubushushu. Kwi-Alloys 316 kunye ne-317L isisombululo se-anneal sifezekiswa ngokufudumeza kwi-1900 ukuya kwi-2150 ° F (1040 ukuya kwi-1175 ° C) uluhlu lobushushu olulandelwa kukupholisa komoya okanye ukucinywa kwamanzi, kuxhomekeke kubukhulu becandelo. Ukupholisa kufuneka kukhawuleze ngokwaneleyo ngoluhlu lwe-1500 ukuya kwi-800 ° F (816 ukuya kuma-427°C) ukuthintela ukuphindaphindwa kwe-chromium carbides kunye nokubonelela ngokuxhathisa ukubola. Kuzo zonke iimeko, isinyithi kufuneka sipholiswe kwiqondo lokushisa lokutshisa ubushushu obumnyama ngaphantsi kwemizuzu emithathu.
Ukuqulunqa
Uluhlu lweqondo lokushisa lokuqala olucetyiswayo luyi-2100-2200 ° F (1150-1205 ° C) kunye nokugqiba kwe-1700-1750 ° F (927-955 ° C).
Ukuhlaziya
I-317LMN kunye ne-Alloy 317L i-stainless steels inokuthi ifakwe kwiqondo lokushisa kwe-1975-2150 ° F (1080-1175 ° C) ilandelwa ngumoya opholileyo okanye ukucima amanzi, kuxhomekeke kubukhulu. Amacwecwe kufuneka afakwe phakathi kwe-2100 ° F (1150 ° C) kunye ne-2150 ° F (1175 ° C). Isinyithi kufuneka sipholiswe kwiqondo lokushisa le-annealing (ukusuka ebomvu / emhlophe ukuya kumnyama) ngaphantsi kwemizuzu emithathu.
Ukuba lukhuni
- La mabanga anzima ngonyango lobushushu.
- I-alloys 316 kunye ne-317L ityhubhu yensimbi engenasici ayinakuqiniswa ngonyango lobushushu.
FAQUmbuzo: Ngaba uyinkampani yokurhweba okanye umenzi?
A: Siyinkampani yokurhweba enamava angaphezulu kweminyaka eyi-15 kwishishini lokuthumela ngaphandle kwentsimbi, sinentsebenziswano yexesha elide kunye neenjini ezinkulu eTshayina.
Umbuzo: Ngaba uza kuzisa iimpahla ngexesha?
A:Ewe, sithembisa ukubonelela ngeemveliso ezikumgangatho ophezulu kunye nokuhanjiswa ngexesha.Ukunyaniseka ngumgaqo wenkampani yethu.
Q:Ngaba ubonelela ngeesampulu? ngaba simahla okanye ngaphezulu?
A: Isampulu inokubonelela umthengi simahla, kodwa imithwalo yekhuriya iya kuhlawulwa yiakhawunti yomthengi.
Q: Ngaba uyalwamkela uhlolo lomntu wesithathu?
A: Ewe siyavuma ngokupheleleyo.
Q: Zeziphi iimveliso zakho eziphambili?
A: Intsimbi yeCarbon, intsimbi yealloyi, ipleyiti yensimbi engenasici/coil, umbhobho nofakelo, amacandelo njl.
Q: Ngaba uyayamkela iodolo eyenziwe ngokwezifiso?
A: Ewe, siyaqinisekisa.
