I-UNS S31703 ayinasici

I-317L yintsimbi ye-austenitic ethwala i-molybdenum enokonyuka kakhulu kokuchasa uhlaselo lwekhemikhali xa ithelekiswa ne-chromium-nickel yesiqhelo yeentsimbi ze-austenitic ezifana no-Type 304. I-317L alloy ikwabonelela ngokunyuka okuphezulu, uxinzelelo-ukugqabhuka, kunye namandla okuqina kumaqondo obushushu aphakamileyo. kuneentsimbi eziqhelekileyo ezingenasici. I-alloy inekhabhoni ephantsi ukubonelela ukuchasana nokuvuselela ngexesha le-welding kunye nezinye iinkqubo ze-thermal. Le alloy yenzelwe iimeko zenkonzo ezinzima ezifana ne-flue gas desulfurization (FGD) iinkqubo.

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 lokutshisa
Ukuhlaziya
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.
