316/316L vs 304/304L

Uhlobo lwe-316 / 316L / 316H yintsimbi ye-austenitic stainless eyenzelwe ukusetyenziswa kwizicelo ezifuna amandla aphezulu, ukuqina kunye nokusebenza, kunye nokunyanzeliswa kwe-corrosion resistance.Thelekisa i-304 yensimbi engenasici, i-316 iqulethe ipesenti ephezulu ye-molybdenum (i-Mo 2% -3%) kunye ne-nickel (i-Ni 10% ukuya kwi-14%), i-Molybdenum inokumelana ne-corrosion engcono, ngakumbi kwi-pitting kunye ne-crevice corrosion kwiindawo ze-chloride.I-316 inokuqina okugqwesileyo kunye neempawu zoomatshini kumaqondo obushushu angaphantsi kwe-zero, alungele ukuqengqeleka okubandayo, ipleyiti yokusila eqhubekayo kunye nefomu yeplate ye-millplate, ububanzi bufikelela kwi-intshi ezingama-60.

316L/TP316L uMbhobho weNtsimbi eNgatyiwayo

IBanga le-316L libhekisela kwi-S31603 i-UNS desination 1.4404, inokumelana ne-corrosion engcono kune-TP316 ngenxa ye-Carbon content ephantsi.I-316L i-carbon content content 0.03% apho i-316 iphezulu i-0.08%, i-carbon ephezulu iya kwandisa i-intergranular corrosion.Ngoko ke, i-316L ifanelekile kwizicelo apho i-carbon precipitation kufuneka igwenywe.Le ntsimbi engenasici isetyenziselwa ukuwelda amacandelo, umxholo wayo okhethekileyo wekhabhoni udityaniswe ne-welding iqinisekisa ukuxhathisa okuphezulu kwi-corrosion jikelele, ngakumbi isebenzayo kumacandelo omsebenzi onzima.

I-316L ithathwa njengexhathisa ngakumbi kwi-oxidation kune-Type 316, ngakumbi kwiindawo ezifudumele zaselwandle.Kwakhona, umxholo wayo ophantsi wekhabhoni uyikhusela kwimvula yekhabhoni.Isinyithi sikwabonisa ukuxhathisa kumaqondo obushushu aphantsi kakhulu, ukuya kuthi ga kumanqanaba e-cryogenic.Ngokubhekiselele ekuxhathiseni ubushushu, i-316L ibonisa ukuxhathisa okungcono kwe-creep, ukumelana noxinzelelo lwe-fracture kunye namandla onke kunamanye amabakala ensimbi engenasici.

Uninzi lweendlela zokusebenza ezifanayo ezisebenzayo kuHlobo lwe-316 zinokusetyenziselwa i-316L, kubandakanya ukuwelda kunye nokuqina komsebenzi obandayo.Ukongeza, i-316 ayifuni ukuhlanjululwa kwangemva kwenkonzo ukuze kwandiswe ukuxhathisa kwayo ekudlekeni, kodwa i-annealing ingasetyenziswa kwezinye iimeko.

316H/TP316H iNtsimbi eNgatyiwayo

I-Grade 316H ibhekisela kwi-S31609, umxholo wekhabhoni i-0.04% ukuya kwi-0.10%, inika ukuchasana kweqondo lokushisa ngaphezu kwe-316L.

316Ti/TP316Ti

Insimbi engenasici i-316Ti yaziwa njengebakala elizinzileyo lohlobo lwe-316 kwaye ikwayenye yeentsimbi ezimbini ze-316 ezicetyiswayo kwizicelo eziphezulu zobushushu.Eli bakala liqulethe ixabiso elincinci (ngokuqhelekileyo yi-0.5%) ye-titanium.Ngelixa isabelana ngeepropathi ezininzi zamanye amabakala angama-316, ukongezwa kwe-titanium kukhusela i-316Ti kwimvula kumaqondo obushushu aphezulu, nokuba kuvezwa ixesha elide.

I-Molybdenum yongezwa ekuqulunqweni kwe-316Ti.Njengamanye amabanga angama-316, i-molybdenum ibonelela ngokhuseleko olongeziweyo ngokuchasene nokuhlwa, ukugonywa kwesisombululo sekloride kunye nokomelela xa ibekwe kwindawo yobushushu obuphezulu.Nangona kunjalo, ukuxhathisa kwayo kwiqondo lobushushu eliphezulu kudityaniswa nomxholo wayo we-titanium, eyenza i-316Ti ikhuseleke kwimvula kula maqondo obushushu.Ukongeza, isinyithi simelana ne-acids efana ne-sulfuric acid, i-hydrochloric acid, kunye ne-acid sulfates.
I-316Ti isetyenziswa ngokuqhelekileyo kwiindawo zokutshintsha ubushushu, izixhobo zokugaya amaphepha kunye nezixhobo zokwakha kwiindawo zaselwandle.

TP316LN/316N

I-316N: I-Nitrogen (N) yongezwa kwi-316 yensimbi engenasici ukunyusa amandla ngaphandle kokunciphisa iplastiki, ukwenzela ukuba ubukhulu bezinto buncitshiswe.Amalungu aphezulu anamandla anokumelana nokugqwala okungcono.

I-316LN ngokunjalo yi-316L kunye ne-N yongeziweyo, inokumelana ne-corrosion engcono kune-316N.

TP316/316L/316H/316Ti iStainless Steel Pipe Applications

Umbhobho we-TP316 / 316L ongenamthungo usetyenziselwa ukuhanjiswa koxinzelelo lwamanzi okanye igesi kunyango lwamanzi, ukucocwa kwamanzi amdaka, i-petrochemical, ikhemikhali, amayeza kunye namanye amashishini.Kwaye usetyenziso lwezakhiwo lubandakanya ii-handrails, iipali kunye nombhobho wenkxaso wamanzi anetyuwa kunye neendawo ezinobungozi.Xa kuthelekiswa ne-TP304 yensimbi engenasici, i-TP316 ipayipi yensimbi engenasici ine-weldability ephantsi, ngoko ke ayisetyenziswa rhoqo njengombhobho odityanisiweyo ngaphandle kokuba ukuxhathisa kwayo okuphezulu kudlula ukuwelda.
