317L Stainless Steel Overview
317L ke molybdenum e behang, "L" e nang le khabone e tlaseaustenitic tšepe e sa hloekange fanang ka khanyetso e ntlafetseng ea kutu ho feta 304L le 316L litšepe tse sa hloekang. Khabone e tlase e fana ka khanyetso ea ts'usumetso nakong ea welding le lits'ebetso tse ling tsa mocheso.
317L ha e na makenete maemong a annealed empa e ka fetoha makenete hanyane ka lebaka la welding.
Khanyetso ea Corrosion
317L e na le khanyetso e ntle haholo ea ho senya lik'hemik'hale tse ngata, haholo-holo libakeng tse nang le acidic chloride tse kang tse kopanang le makhasi a pampiri le pampiri. Maemo a eketsehileng a chromium, nickel le molybdenum ha a bapisoa le 316L tšepe e sa hloekang a ntlafatsa ho hanyetsa chloride pitting le corrosion e akaretsang. Ho hanyetsa ho eketseha ka litaba tsa molybdenum alloy. 317L e hanyetsana le metsoako ea sulfuric acid ho fihlela ho karolo ea 5 lekholong mocheso o ka holimo ho 120 ° F (49 ° C). Ka mocheso o ka tlase ho 100 ° F (38 ° C) motsoako ona o na le khanyetso e ntle ho tharollo ea khatello e phahameng. Leha ho le joalo, liteko tsa lits'ebeletso li khothaletsoa ho ikarabella bakeng sa litlamorao tsa maemo a itseng a ts'ebetso a ka amang boits'oaro ba kutu. Lits'ebetsong moo condensation ea likhase tse nang le sebabole li hlahang, 317L e hanyetsa haholo ho hlasela sebakeng sa condensation ho feta alloy e tloaelehileng 316. Letlapa la asiti le na le tšusumetso e kholo ea sekhahla sa tlhaselo libakeng tse joalo 'me e lokela ho khethoa ka hloko ke tšebeletso. liteko.

Welding 317L
317L e chesetsoa habonolo ke mekhoa e mengata e tloaelehileng ea ho cheselletsa (ntle le oxyacetylene). AWS E317L/ER317L tšepe kapa austenitic, litšepe tse tlase tsa khabone tse nang le molybdenum tse phahameng ho feta tsa 317L, kapa tšepe ea nickel-base filler e nang le chromium le molybdenum e lekaneng ho feta khanyetso ea kutu ea 317L e lokela ho sebelisoa ho cheselletsa tšepe ea 317L.
