Nkọwa Dị Mkpirikpi:

Alloy 2507, nke nwere nọmba UNS S32750, bụ alloy nke nwere usoro ígwè-chromium-nickel, nke nwere usoro agwakọtara agwakọta nke nha nhata nke austenite na ferrite. N'ihi nhazi nke usoro duplex, Alloy 2507 na-egosipụta ezigbo iguzogide nchara nkịtị dịka nke ígwè anaghị agba nchara austenitic nwere ihe ndị yiri ya. E wezụga nke ahụ, ọ nwere ike nrụgide na mmepụta dị elu yana iguzogide chloride SCC ka mma karịa ndị otu austenitic ya, ebe ọ na-anọgide na-enwe ike mmetụta ka mma karịa ndị otu ferritic.

Super Duplex igwe anaghị agba nchara dịka S32750, bụ ngwakọta nke austenite na ferrite (50/50) nke mere ka ike dịkwuo mma karịa ọkwa ígwè ferritic na austenitic. Isi ihe dị iche bụ na Super Duplex nwere molybdenum na chromium dị elu nke na-eme ka ihe ahụ ka mma Chromium dị elu na-akwalitekwa nhazi nke usoro intermetallic na-emerụ ahụ, nke na-enwe mmetụta na 475°C embrittlement n'ihi mmiri ozuzo nke chromium-rich α phase, yana embrittle site na sigma, chi na usoro ndị ọzọ na okpomọkụ dị elu.

Alloy 2507 (S32750) nwekwara oke nitrogen, nke na-akwalite mmepụta nke austenite ma na-eme ka ike dịkwuo elu, kamakwa ọ na-egbu oge nhazi nke usoro intermetallic zuru oke iji kwe ka nhazi na imepụta nke ọkwa duplex.

A na-amata ọkwa ya site na ezigbo iguzogide nchara chloride, yana ike igwe dị elu. Ọ dabara nke ọma maka ojiji na gburugburu ebe siri ike dịka mmiri mmiri na-ekpo ọkụ na-ekpo ọkụ na ihe ndị nwere acidic chloride.

Njirimara nke Alloy 2507 (S32750) bụ ndị a:

● Ezigbo iguzogide mgbawa nrụrụ nrụgide (SCC) na gburugburu ebe obibi chloride
● Nguzogide dị mma megide nsị na mmebi oghere
● Nnukwu iguzogide nchara nkịtị
● Ike igwe dị oke elu
● Ọdịdị anụ ahụ nke na-enye uru imewe
● Ike ọgwụgwụ nke mbuze na ike ọgwụgwụ nke ire ere siri ike
● Ezi ike ịgbado ọkụ

E mere S32750 maka ngwa ndị siri ike nke chọrọ ike pụrụ iche na nguzogide nchara, nke dị nausoro kemịkalụ, ngwa petrochemical, na mmiri mmiri.
