Malunga ne-316L ipayipi yensimbi engenasici

I-316L libakala lensimbi engenasici, i-AISI 316L ligama elihambelanayo laseMelika, kwaye i-sus 316L ligama elihambelana neJapan.ikhowudi yedijithali emanyeneyo yelizwe lam yi-S31603, ibakala elisemgangathweni ngu-022Cr17Ni12Mo2 (umgangatho omtsha), kunye nebakala elidala ngu-00Cr17Ni14Mo2, oku kuthetha ukuba iqulethe i-Cr, i-Ni, kunye ne-Mo, kwaye inani limele ipesenti eqikelelweyo.

Ubuninzi bekhabhoni ye-316 ipayipi yensimbi engenasici yi-0.03, engasetyenziselwa izicelo apho i-annealing emva kwe-welding ayinakwenziwa kwaye i-corrosion resistance resistance iyadingeka.
I-316 kunye ne-317 insimbi engenasici (jonga ngezantsi kwiipropati ze-317 zensimbi ezingenasici) ziyi-molybdenum-containing steels.
Ukusebenza ngokubanzi kolu didi lwensimbi lungcono kune-310 kunye ne-304 yensimbi engenasici.Ngaphantsi kweemeko eziphezulu zokushisa, xa ukuxinwa kwe-asidi ye-sulfuric kungaphantsi kwe-15% kwaye kuphezulu kune-85%, i-316 insimbi engenasici ineendlela ezininzi zokusetyenziswa.
I-316 ipleyiti yentsimbi, ekwabizwa ngokuba yi-00Cr17Ni14Mo2 ukuxhathisa umhlwa:
Ukumelana ne-corrosion kungcono kune-304 yensimbi engenasici, kwaye inokumelana ne-corrosion efanelekileyo kwinkqubo yokuvelisa i-pulp kunye nephepha.
Ukumelana ne-carbide precipitation ye-316 insimbi engenasici ingcono kune-304 yensimbi engenasici, kwaye uluhlu lweqondo lokushisa olungentla lunokusetyenziswa.

316l umbhobho wentsimbi engenastainless umgangatho wesizwe

I-316L inoluhlu olubanzi lwezicelo kwishishini lemichiza ngenxa yokumelana nokugqwesa kwayo.I-316L nayo i-derivative ye-18-8 uhlobo lwe-austenitic stainless steel, kunye ne-2 ukuya kwi-3% ye-Mo yongezwa.Kwisiseko se-316L, amabakala amaninzi ensimbi nawo aphuma.Ngokomzekelo, i-316Ti ithathwa emva kokongeza inani elincinci le-Ti, i-316N ithathwa emva kokongeza inani elincinci le-N, kwaye i-317L ithathwa ngokunyusa umxholo we-Ni kunye ne-Mo.

Uninzi lwe-316L ekhoyo kwimarike iveliswa ngokwe-American Standard.Ngezizathu zeendleko, iintsimbi zentsimbi zizama ngokubanzi ukuthoba umxholo we-Ni weemveliso zabo ukuya kumda ophantsi.Umgangatho waseMelika uchaza ukuba umxholo we-Ni we-316L yi-10-14%, ngelixa umgangatho waseJapan uchaza ukuba umxholo we-Ni we-316L yi-12-15%.Ngokomgangatho ophantsi, kukho umahluko we-2% kumxholo we-Ni phakathi komgangatho waseMelika kunye nomgangatho waseJapan, omkhulu kakhulu ngokwexabiso.Ke ngoko, abathengi basafuna ukubona ngokucacileyo xa kuthengwa iimveliso ze-316L, nokuba iimveliso zibhekisa kwimigangatho ye-ASTM okanye ye-JIS.

Umxholo we-Mo we-316L wenza le ntsimbi ibe nokuchasana ngokugqwesileyo kwi-corrosion ye-pitting kwaye ingasetyenziselwa ngokukhuselekileyo kwiindawo eziqulethe i-Cl- kunye nezinye i-halogen ions.Ekubeni i-316L isetyenziselwa ubukhulu becala kwiimpawu zayo zeekhemikhali, iintsimbi zetsimbi zineemfuno ezingaphantsi kancinci zokuhlolwa kwendawo ye-316L (xa kuthelekiswa ne-304), kwaye abathengi abaneemfuno eziphezulu eziphezulu kufuneka bomeleze ukuhlolwa kwendawo.

Ukugcinwa kunye nokucocwa kwensimbi engenasici

Ukuba insimbi engenasici ibonakaliswe emoyeni ixesha elide, iya kuba mdaka njengayo nayiphi na enye into.Uphononongo lubonise ukuba iindlela ezimbini ezahlukeneyo zokuhlamba imvula kunye nokuhlamba ngesandla zinobudlelwane obuthile kunye nomphezulu ongcolileyo wensimbi engenasici.Okokuqala, beka isileti sentsimbi engatyiwayo emoyeni kunye nenye kwicanopy ukujonga ifuthe lokuhlanjwa kwemvula.Inkqubo yokusebenza yokucoca ngesandla kukusebenzisa isiponji esifakelweyo esifakwe emanzini anesepha ukulungisa rhoqo indawo yee-slats eziphathekayo, kwaye ixesha ziinyanga ezi-6 zokukhuhla.Ngenxa yoko, ezo slats zazingagungxulwanga kwishedi zazinothuli oluncinane kakhulu kumphezulu wee-slats ezigungxulwayo kunezo zazigungxulwa ngeendlela zombini.Ngoko ke, ixesha lokucocwa kwensimbi engenasici nalo lingachaphazeleka kwizinto ezininzi.Ebomini, sinokuhlambulula kuphela isinyithi esingenasici xa sihlambulula iglasi, kodwa ukuba insimbi engenasici ingaphandle, kucetyiswa ukuba ihlanjwe kabini ngonyaka.
