Isixhobo sentsimbi:

Izinto zetsimbi estainless luhlobo lwemathiriyeli, isondele kwisibuko sokukhanya, ukubamba nzima kunye nokubanda, yeyezinto zokuhombisa ngaphezulu kwe-avant-garde, inokumelana nokugqwesa okugqwesileyo, ukubumba, ukuhambelana kunye nokuqina kunye nezinye iimpawu zothotho, ezisetyenziswa kushishino olunzima. , ishishini elikhanyayo, ishishini lempahla yasekhaya kunye nokuhlobisa izakhiwo kunye namanye amashishini.

Acid stainless steel resistant ekubhekiselwa kuyo njengentsimbi estainless, yenziwe ngentsimbi estainless kunye neasidi enganyangekiyo ngamacandelo amabini, ngamafutshane, inokumelana nokuhlwa kwentsimbi yomoya ebizwa ngokuba yintsimbi engatyiwayo, kwaye inokumelana nekhemikhali ephakathi kwentsimbi ebizwa ngokuba yi-asidi resistant steel. Ngokubanzi. ukuthetha, umxholo we-chromium we-Cr mkhulu kune-12% yentsimbi ineempawu zensimbi engenasici.

Ulwahlulo lwentsimbi engatyiwa:

Kukho iindlela ezininzi zokuhlela insimbi engenasici, phakathi kwazo ezo ziqhelekileyo zilandelayo.

Ukuhlelwa kolwakhiwo lwe-metallographic:

Inokwahlulwa ibe yintsimbi ye austenitic stainless, ferrite steel stainless, martensitic stainless steel, duplex steel stainless, precipitation iqinisa intsimbi.

Ukuhlelwa kokwakheka kweekhemikhali:

Ngokwesiseko inokwahlulwa ibe yintsimbi ye-chromium (efana nochungechunge lwe-ferrite, inkqubo ye-martensite) kunye nentsimbi ye-nickel ye-chromium (njengenkqubo ye-austenite, uchungechunge olungaqhelekanga, uchungechunge lwe-precipitation lukhuni) iinkqubo ezimbini.

Ngokohlobo lokumelana nomhlwa:

Inokwahlulwa ibe yintsimbi enganyangekiyo yoxinzelelo, i-corrosion resistant steel stainless, intergranular corrosion resistant steel stainless, njl.

Ihlelwa ngokweempawu zokusebenza:

Inokwahlulwa ibe yintsimbi yokusika yasimahla, intsimbi engenamagnetic, intsimbi ephantsi yobushushu obuphantsi, amandla aphezulu entsimbi.

Kukho phantse iintlobo ze-100 zensimbi engenasici eziye zabandakanywa kwimigangatho eyahlukeneyo yehlabathi, kunye nenkqubela phambili yesayensi kunye nobuchwepheshe kunye nophuhliso loshishino kunye nezolimo, amabakala amatsha ensimbi engenasici nawo ayanda.Ukwenzela ibakala elaziwayo lensimbi engenasici. , i-chromium elinganayo [i-Cr] kunye ne-nickel elinganayo [i-Ni] ingabalwa ngokwemichiza yayo, kunye ne-microstructure kunye neempawu zentsimbi zingaqikelelwa ngokumalunga ngokusebenzisa itshathi ye-microstructure ye-Schaeffler-Delong yensimbi engenasici.

Ukuhlelwa kweMatrix:

I-1, i-ferrite stainless steel.Chromium 12% ~ 30%.Ukumelana kwayo nokugqwala, ukuqina kunye nokunyuka kwe-weldability kunye nokunyuka komxholo we-chromium, kunye nokuxhatshazwa kwe-chloride yoxinzelelo lwe-corrosion lungcono kunezinye iintlobo zensimbi engenasici.

2. I-Austenitic steel stainless.Iqulethe ngaphezu kwe-18% ye-chromium, malunga ne-8% ye-nickel kunye nenani elincinci le-molybdenum, i-titanium, i-nitrogen kunye nezinye izinto.Ukusebenza kakuhle okubanzi, ukuxhathisa ukubola kwiindidi ezahlukeneyo zeendaba.

3. I-Austenite-ferrite duplex steel stainless.Ineenzuzo ze-austenite kunye ne-ferrite insimbi engenasici, kwaye ine-superplasticity.

I-Martensitic steel stainless.Amandla aphezulu, kodwa iplastiki empofu kunye ne-weldability.

Itheyibhile yokuthelekisa inombolo yentsimbi yensimbi engenasici kunye netafile yoxinaniso
