Alloy 20 igwe anaghị agba nchara

UNS N08020

UNS N08020, nke a makwaara dị ka Alloy 20 bụ otu n'ime igwe anaghị agba nchara nke "super" nke emepụtara maka oke iguzogide ọgụ acid, n'ihi nke a, enwere ojiji dị iche iche maka ya na ụlọ ọrụ igwe anaghị agba nchara na nickel. Alloy 20 yiri ka ọ dabara n'etiti ma igwe anaghị agba nchara na nickel, ebe ọ nwere njirimara nke abụọ; Otú ọ dị, usoro ọnụọgụgụ ọnụ (UNS) na-emecha mata ya dị ka alloy dabeere na nickel, ya mere nọmba UNS N08020.

Alloy 20 bụ ihe austenitic nickel-iron-chromium nke dabere na ihe mgbakwunye ọla kọpa na molybdenum. Ọdịnaya nickel ya na-enyere aka na nrụgide ion chloride ya na nguzogide corrosion. Mgbakwunye nke ọla kọpa na molybdenum na-enye iguzogide gburugburu ebe ndị iro, pitting na crevice corrosion. Chromium na-agbakwụnye na nguzogide ya nke gburugburu oxidizing, dị ka nitric acid, na columbium (ma ọ bụ niobium) na-ebelata mmetụta nke mmiri ozuzo carbide. Enwere ike iji ọtụtụ ụzọ ịgbado ọkụ mgbe ị na-arụ ọrụ na Alloy 20, ma e wezụga maka ịgbado ọkụ oxyacetylene. Ọ nwekwara ike na-ekpo ọkụ kpụrụ na-eji otu agha chọrọ na-ekpo ọkụ ọrụ austenitic igwe anaghị agba nchara. N'ihe gbasara igwe, ọ ga-ekwe omume ịmecha ihe pụtara ìhè site na iji otu nhazi na usoro ọsọ nke ejiri maka igwe anaghị agba nchara austenitic, dị ka igwe anaghị agba nchara 316 ma ọ bụ 317.
