317L iStainless Steel Overview
I-317L yi-molybdenum ethwala, umxholo wekhabhoni ephantsi "L" ibakalaintsimbi ye-austeniticebonelela ngokuphucuka kokumelana ne-corrosion ngaphezu kwe-304L kunye ne-316L yeentsimbi ezingenasici. Ikhabhoni ephantsi inikezela ukuchasana nokuvuselela ngexesha le-welding kunye nezinye iinkqubo ze-thermal.
I-317L ayiyo-magnetic kwimeko ye-annealed kodwa inokuba yimagnethi kancinane ngenxa ye-welding.
Ukunyangwa kokuMhlwa
I-317L ine-corrosion resistance resistance kuluhlu olubanzi lweekhemikhali, ngakumbi kwiindawo ezine-acidic chloride ezifana nezo zidibene ne-pulp kunye nephepha lokugaya. Ukunyuka kwamanqanaba e-chromium, i-nickel kunye ne-molybdenum xa kuthelekiswa ne-316L yensimbi engenasici iphucula ukuchasana ne-chloride pitting kunye ne-corrosion jikelele. Ukuchasana kuyanda kunye nomxholo we-molybdenum alloy. I-317L iyamelana ne-sulfuric acid concentrations ukuya kwiipesenti ze-5 kumaqondo okushisa aphezulu njenge-120 ° F (49 ° C). Kwiqondo lokushisa elingaphantsi kwe-100 ° F (38 ° C) le alloy inokumelana okugqwesileyo kwizisombululo zoxinzelelo oluphezulu. Nangona kunjalo, iimvavanyo zenkonzo ziyacetyiswa ukuba ziphendule ngeempembelelo zeemeko ezithile zokusebenza ezinokuchaphazela ukuziphatha kokubola. Kwiinkqubo apho i-condensation ye-sulfur-bearing gases iyenzeka, i-317L ixhaphake kakhulu ekuhlaselweni kwindawo yokudibanisa kune-alloy yesiqhelo 316. Uxinzelelo lwe-asidi lunempembelelo ephawulekayo kwizinga lokuhlaselwa kwiindawo ezinjalo kwaye kufuneka zinqunywe ngokucophelela ngenkonzo. iimvavanyo.

Ukuwelda 317L
I-317L ifakwe ngokukhawuleza uluhlu olupheleleyo lweenkqubo ze-welding eziqhelekileyo (ngaphandle kwe-oxyacetylene). I-AWS E317L / ER317L isinyithi okanye i-austenitic, isinyithi esisezantsi se-carbon filler kunye nomxholo we-molybdenum ophezulu kune-317L, okanye i-nickel-base metal filler ene-chromium eyaneleyo kunye nomxholo we-molybdenum ukudlula ukuxhathisa ukubola kwe-317L kufuneka isetyenziswe ukutshisa i-317L yentsimbi.
