a. 254SMO bụ igwe anaghị agba nchara austenitic. N'ihi ọdịnaya molybdenum dị elu, ọ nwere nnukwu nguzogide ịhụ corrosion

na crevice corrosion.

b. A na-emepụta ụdị igwe anaghị agba nchara maka iji na gburugburu nwere halides dị ka mmiri oké osimiri. 254SMO nwekwara ihe ọma

iguzogide edo corrosion.

c. Karịsịa na acid nwere halide, nchara dị elu karịa igwe anaghị agba nchara nkịtị. Ọdịnaya C ya bụ <0.03%, yabụ a na-akpọ ya

ezigbo austenitic igwe anaghị agba nchara (<0.01% ka a na-akpọkwa super austenitic igwe anaghị agba nchara). Super igwe anaghị agba nchara bụ ụdị igwe anaghị agba nchara pụrụ iche.

d. Mbụ niile, ọ dị iche na nkịtị igwe anaghị agba nchara na chemical mejupụtara. Ọ na-ezo aka n'ụdị nnukwu alloy igwe anaghị agba nchara

nwere nickel dị elu, chromium dị elu na molybdenum dị elu. Nke a ma ama bụ 254SMo nwere 6% Mo. Ụdị ígwè a

e. Ọ nwere ezigbo nguzogide corrosion nke pitting (PI ≥ 40) na nrụgide corrosion nguzogide n'okpuru ọnọdụ nke mmiri mmiri, ikuku, crevice.

na obere ịhịa aka n'ahụ.

f. Ọ bụ ihe nnọchi maka Ni base alloy na titanium alloy. Nke abuo, n'ihe banyere elu okpomọkụ iguzogide ma ọ bụ corrosion iguzogide.

ọ nwere nguzogide okpomoku dị elu ma ọ bụ nguzogide corrosion, nke a na-apụghị dochie anya igwe anaghị agba nchara 304. Na mgbakwunye,

site na nhazi nke igwe anaghị agba nchara, ihe metallographic nhazi nke igwe anaghị agba nchara pụrụ iche bụ ihe owuwu austenitic metallographic kwụsiri ike.
