316L iNtsimbi eNgatyiwayo

Ukuqulunqwa, Iimpawu kunye nezicelo

Ukuqonda i-316L yensimbi engenasici, umntu kufuneka aqale aqonde i-316 yensimbi engenasici.

I-316 yintsimbi ye-chromium-nickel ye-austenitic ephakathi kwe-2 kunye ne-3% ye-molybdenum.Umxholo we-molybdenum uphucula ukuxhathisa kwe-corrosion, ukwandisa ukuchasana nokugoba kwi-chloride ion solutions, kunye nokuphucula amandla kumaqondo aphezulu.

Yintoni i-316L iStainless Steel?

I-316L yinqanaba lekhabhoni ephantsi ye-316. Eli bakala likhuselekile kwi-sensitization (grain boundary carbide precipitation).Isetyenziswa rhoqo kwigeyiji enzima edityanisiweyo (malunga ne-6mm).Akukho mahluko uphawuleka ixabiso phakathi 316 kunye 316L steel stainless.

I-316L insimbi engenasici inikezela ngokunyuka okuphezulu, uxinzelelo lokuqhekeka kunye namandla okuqina kumaqondo obushushu aphakamileyo kune-chromium-nickel austenitic steels stainless.

Ukutyunjwa kwe-alloy

Igama elithi “L” lithetha nje “ikhabhoni encinane.”I-316L iqulethe i-carbon encinci kune-316.

Ukutyunjwa okuqhelekileyo yi-L, F, N, kunye ne-H. Ubume be-austenitic bala mabanga bunika ubunzima obugqwesileyo, nakwiqondo lokushisa le-cryogenic.

304 vs. 316 Intsimbi engatyiwa

Ngokungafaniyo nentsimbi ye-304 - eyona nto idume kakhulu insimbi engenasici - i-316 inezinto eziphuculweyo zokumelana nokubola kwi-chloride kunye nezinye i-acids.Oku kwenza ukuba kube luncedo kwizicelo zangaphandle kwiindawo zaselwandle okanye izicelo ezinomngcipheko wokuvezwa kwikloridi.

Zombini i-316 kunye ne-316L zibonisa ukuxhathisa okungcono kwe-corrosion kunye namandla kumaqondo obushushu aphezulu kunomlingani wabo we-304 - ngakumbi xa kuziwa kwi-pitting kunye ne-crevice corrosion kwiindawo ze-chloride.

316 vs. 316L iNtsimbi eNgatyiwayo

I-316 insimbi engenasici iqulethe i-carbon eninzi kune-316L.I-316 insimbi engenasici inomgangatho ophakathi woluhlu lwekhabhoni kwaye iqulethe phakathi kwe-2% kunye ne-3% ye-molybdenum, enika ukuxhathisa ukubola, izinto ezine-acidic, kunye namaqondo obushushu aphezulu.

Ukuze ufaneleke njenge-316L yensimbi engenasici, inani lekhabhoni kufuneka libe liphantsi - ngokukodwa, alikwazi ukudlula i-0.03%.Amanqanaba asezantsi ekhabhoni abangela ukuba i-316L ibe thambileyo kune-316.

Nangona umehluko kumxholo wekhabhoni, i-316L ifana kakhulu ne-316 phantse zonke iindlela.

Zombini iintsimbi ezingenastainless zinyibilika kakhulu, ziluncedo xa kusenziwa iimilo eziyimfuneko kuyo nayiphi na iprojekthi ngaphandle kokwaphuka okanye nokuqhekeka, kwaye zinokumelana okuphezulu kokubola kunye nokomelela okuphezulu.

Iindleko phakathi kwezi ntlobo zimbini ziyathelekiseka.Zombini zibonelela ngokuqina okuhle, ukuxhathisa umhlwa, kwaye zikhetho ezifanelekileyo kwizicelo ezinoxinzelelo oluphezulu.

I-316L ithathwa njengefanelekileyo kwiprojekthi efuna i-welding enkulu.I-316, kwelinye icala, ayinyangeki ku-corrosion ngaphakathi kwe-weld (i-weld decay) kune-316L.Oko kuthethiweyo, ukudibanisa i-316 yindlela yokusebenza yokuxhathisa ukubola kwe-weld.

I-316L ilungile kubushushu obuphezulu, ukusetyenziswa kwe-corrosion ephezulu, ebonisa ukuthandwa kwayo kulwakhiwo kunye neeprojekthi zaselwandle.

Zombini i-316 kunye ne-316L zinokusebenza kakuhle, ziqhuba kakuhle ekugobeni, ukolula, ukuzoba nzulu, kunye nokujikeleza.Nangona kunjalo, i-316 yintsimbi eqinile ngakumbi enamandla amakhulu kunye ne-ductility xa kuthelekiswa ne-316L.

• Iipropati ze-316L

  I-316L insimbi engenasici ibonakala ngokulula ngokuhlola umxholo wayo wekhabhoni - omele ube ngaphantsi kwe-316. Ngaphandle koko, nantsi ezinye iipropati ze-316L ezikwahlula kwamanye amabakala ensimbi.

  Iipropati Zomzimba

  I-316L inobuninzi be-8000 kg / m3 kunye ne-elastic modulus ye-193 GPa.Kwiqondo lokushisa kwe-100 ° C, inonxibelelwano lwe-thermal ye-16.3 W / mK kunye ne-21.5 W / mK kwi-500 ° C.I-316L ikwane-resistivity yombane ye-740 nΩ.m, kunye nomthamo othile wokushisa we-500 J/kg.K.

  Ukuqulunqwa kwemichiza

  Ukubunjwa kwe-316l SS kubonisa amanqanaba aphezulu ekhabhoni ye-0.030%.Amanqanaba e-silicon aphezulu kwi-0.750%.Ubuninzi be-manganese, i-phosphorus, i-nitrogen, kunye ne-sulfure amanqanaba abekwe kwi-2.00%, 0.045%, 0.100% kunye ne-0.030%, ngokulandelanayo.I-316L yenziwe ngechromium kwi-16% min kunye ne-18% max.Amanqanaba e-nickel abekwe kwi-10% min kunye ne-14% max.Umxholo we-molybdenum ubuncinci bezinga le-2.00% kunye nobuninzi be-3.00%.

  Iipropati zoomatshini

  I-316L igcina ubuncinci bamandla obuncinci be-485 kunye namandla amancinci okuvelisa i-120 kwi-0.2% ubungqina boxinzelelo.Inobude be-40% kwi-50mm / min kunye nobunzima obukhulu be-95kg phantsi kovavanyo lwe-Hardness Rockwell B.I-316L insimbi engenasici ifikelela kubunzima obukhulu be-217kg phantsi kovavanyo lwesikali seBrinell.

  Ukunyangwa kokuMhlwa

  IBanga le-316L libonelela ngokugqwesa ukuxhathisa ukudleka kwiintlobo ngeentlobo zemithombo yeendaba eyonakalisayo kunye nemo engqongileyo yomoya.Ibamba kakuhle xa iphantsi kwemingxuma kunye ne-corrosion kwindawo efudumeleyo yekloridi.Ukongeza, ingqina ukuba ihlala yomelele naphantsi koxinzelelo lovavanyo lokuqhekeka kokutya okungaphezulu kwe-60 °C.I-316L ibonisa ukuchasana namanzi ukuya kuthi ga kwi-1000mg / L amanqanaba e-chloride.

  I-316 grade steel stainless iyasebenza ngokukodwa kwiindawo ezine-acidic - ngakumbi xa ikhusela kwi-corrosion ebangelwa i-sulfuric, i-hydrochloric, i-acetic, i-formic, kunye ne-tartaric acids, kunye ne-acid sulfates kunye ne-alkaline chlorides.
