317/317L intsimbi engatyiwa 6.35 * 0.70mm ityhubhu ebhijelweyo/ityhubhu ethe tye

Umxholo ophezulu we-molybdenum we-Alloy 317L uqinisekisa ukuxhathisa kwe-corrosion jikelele kunye neendawo zendawo kwiindawo ezininzi zeendaba xa kuthelekiswa ne-304 / 304L kunye ne-316 / 316L i-stainless steels.Iimeko ezingqongileyo ezingahlaseli i-304/304L yensimbi engenasici ngokuqhelekileyo ayiyi kugqwala i-317L.Enye into, nangona kunjalo, i-asidi ene-oxidizing enamandla njenge-nitric acid.Ingxubevange enemolybdenum ayisebenzi kakuhle kwezi meko.

I-alloy 317L inokumelana ne-corrosion ebalaseleyo kuluhlu olubanzi lweekhemikhali.Ichasa ukuhlaselwa kwe-sulfuric acid, i-chlorine ene-acidic kunye ne-phosphoric acid.Isetyenziselwa ukuphatha i-organic acids eshushu kunye ne-fatty acids kaninzi ikhona ekutyeni kunye nezicelo zokulungisa amayeza.

Ukuxhatshazwa kwe-corrosion ye-317 kunye ne-317L kufuneka kube yinto efanayo kuyo nayiphi na indawo engqongileyo.Enye ngaphandle apho i-alloy iya kuboniswa kumaqondo obushushu kwi-chromium carbide precipitation range ye-800 - 1500 ° F (427 - 816 ° C).Ngenxa yomxholo wekhabhoni ephantsi, i-317L yeyona nto ikhethwayo kule nkonzo ukugada i-intergranular corrosion.

Ngokubanzi, i-austenitic stainless steels ixhomekeke kwi-chloride yoxinzelelo lwe-corrosion cracking kwinkonzo ye-halide.Nangona i-317L ixhathisa ngakumbi kuxinzelelo lokuqhekeka kwe-corrosion kune-304/304L yeentsimbi ezingenazintsimbi, ngenxa yomxholo wayo ophezulu we-molybdenum, isenokwenzeka.

I-chromium ephezulu, i-molybdenum kunye nomxholo we-nitrogen we-317L uphucula ukukwazi kwayo ukuxhathisa i-pitting kunye ne-crevice corrosion phambi kwee-chlorides kunye nezinye i-halides.I-Pitting Resistance Equivalent kuquka inombolo ye-Nitrogen (PREN) ngumlinganiselo ohambelana nokuchasana kwemigodi.Itshathi elandelayo inika uthelekiso lwe-Alloy 317L kunye nezinye iintsimbi ze-austenitic ezingenasici.
