Inkcazo emfutshane:

Iityhubhu ze-2205 ze-Duplex Stainless Steel. Intsimbi ye-duplex esetyenziswa kakhulu edibanisa amandla aphezulu kunye nokumelana nokugqwala kwii-asidi ezahlukeneyo ze-organic, ii-asidi ze-anorganic, amanzi okupholisa anamandla kunye nemixube ye-hydrous H2 S/NaCl. Ngomxube we-austenite kunye ne-ferrite ophantse ulingane, zinika amandla okuvelisa aphezulu ngama-30% kwaye amandla okutsalwa aphezulu kancinci kune-austenitics equlethe i-nitrogen. Ukumelana okuphezulu kokugqwala ngokubanzi kwaye ngokukodwa ukugqwala kwe-pitting kunye ne-crevice. Ukumelana kwazo nokuqhekeka koxinzelelo-ukugqwala kwii-chloride ezingathathi hlangothi kungcono kunokwe-austenites. Kwiindawo ezine-chloride ephezulu okanye ezimuncu ngokulinganayo apho ukuqhekeka koxinzelelo lwe-hydrogen okanye i-sulphide kunokwenzeka khona, ii-austenitics eziphezulu ezixutyiweyo nazo kufuneka ziqwalaselwe. Amaxabiso empembelelo aphezulu kwaye amaqondo obushushu okuguquka kwezinto ezisisiseko ayahluka malunga ne-50°C. Nangona kunjalo, umlinganiselo kunye nolwalathiso lwe-ferrite kwii-welds kunye nezinto ezisisiseko zinokuchaphazela kakhulu ukuqina kumaqondo obushushu angaphantsi kwe-zero. Ukuvezwa kumaqondo obushushu aphakathi naphezulu kunye nokuphola okuncinci kunokubangela ukubhitya.
