S32750 igwe anaghị agba nchara

Nkọwa dị mkpirikpi:

Alloy 2507, ya na nọmba UNS S32750, ọ bụ alloy nke abụọ dabere na sistemụ iron-chromium-nickel nwere usoro agwakọta nke ihe dịka nha nha nke austenite na ferrite. N'ihi nguzozi nke duplex, Alloy 2507 na-egosipụta nguzogide dị mma na corrosion izugbe dị ka nke austenitic igwe anaghị agba nchara nwere ihe ndị yiri ya. E wezụga nke ahụ, ọ na-enwe ike dị elu ma na-enye ike yana nguzogide chloride SCC dị mma karịa ndị ibe ya austenitic ebe ọ na-ejigide mmetụta siri ike karịa ndị mmekọ ferritic.

Super Duplex igwe anaghị agba nchara dị ka S32750, bụ ngwakọta microstructure nke austenite na ferrite (50/50) nke emeela ka ike dị elu karịa ọkwa nchara ferritic na austenitic. Isi ihe dị iche bụ na Super Duplex nwere molybdenum dị elu na ọdịnaya chromium nke na-enye ihe dị elu chromium dị elu na-akwalitekwa nhazi nke akụkụ intermetallic na-emerụ ahụ, nke na-enwe mmetụta na 475 ° C embrittlement n'ihi mmiri ozuzo nke chromium-ọgaranya α, na embrittlement site sigma, chi na usoro ndị ọzọ.

Alloy 2507 (S32750) nwekwara ọdịnaya nitrogen dị elu, nke ọ bụghị naanị na-akwalite nhazi nke austenite ma na-abawanye ike, ma na-egbu oge nhazi nke usoro intermetallic zuru ezu iji kwe ka nhazi na ịmepụta ọkwa nke duplex.

A na-eji ọkwa ahụ mara ezigbo mma nke nguzogide corrosion chloride, jikọtara ya na ike ọrụ dị oke elu. Ọ dabara nke ọma maka ojiji na gburugburu ebe ihe ike dị ka mmiri mmiri chlorinated na-ekpo ọkụ na mgbasa ozi nwere chloride acid.

Njirimara Alloy 2507 (S32750) bụ ndị a:

● Nguzogide dị mma maka mgbawa corrosion corrosion (SCC) na gburugburu chloride na-ebu
● Nnukwu iguzogide pitting na crevice corrosion
● Nnukwu iguzogide corrosion n'ozuzu
● Ike igwe dị elu
● Njirimara anụ ahụ nke na-enye uru imewe
● Nnukwu iguzogide nbibi na ike ọgwụgwụ corrosion
● Ọdịmma nke ọma

Emebere S32750 maka ngwa na-achọsi ike nke chọrọ ike pụrụ iche na nguzogide corrosion, nke dị na yausoro kemịkalụ, petrochemical, na akụrụngwa mmiri mmiri. A na-eji ya n'ọtụtụ ebe na mmanụ na gas na-eme nchọpụta / mmepụta na n'ime ndị na-ekpo ọkụ ọkụ na nhazi petrochemical / chemical. Ọkwa ahụ dịkwa mma maka ngwa hydraulic na ngwa ngwa na gburugburu oke mmiri.
