254SMo Mea Pono
ʻO 254SMO he kila kuhiliʻole austenitic.Ma muli o kona kiʻekiʻe molybdenum maʻiʻo, he kiʻekiʻe loa kona kū'ē i ka lua a me ka crevice corrosion.Ua hoʻomohala ʻia a hoʻomohala ʻia kēia pae o ke kila kila no ka hoʻohana ʻana i nā kaiapuni i loko o ka halide e like me ka wai kai.He kūpaʻa maikaʻi nō hoʻi ka 254SMO i ka corrosion like.ʻOi aku ka maikaʻi i nā waikawa halide, ʻoi aku ka maikaʻi o ke kila ma mua o ke kila kila maʻamau.Aia i loko o kāna C<0.03%, no laila ua kapa ʻia ʻo ia ke kila kuhili ʻole austenitic (<0.01% kapa ʻia ʻo super austenitic stainless steel).ʻO ke kila kila kila keʻano o ke kila kila kūikawā.ʻO ka mea mua, he ʻokoʻa ia mai ke kila kuhili ʻole maʻamau i ka haku melemele.E pili ana ia i ke kila kila kila kila kiʻekiʻe me ka nickel kiʻekiʻe, ka chromium kiʻekiʻe a me ka molybdenum kiʻekiʻe.I waena o lākou, ka mea kaulana loa he 254SMo i loaʻa iā 6% Mo. ʻO kēia ʻano kila he maikaʻi loa ke kūʻē ʻana i ka corrosion kūloko, a maikaʻi ka pitting corrosion kūpaʻa (PI≥40) a ʻoi aku ka maikaʻi o ke koʻikoʻi koʻikoʻi kūʻē a he pani no Ni- nā mea hoʻohui i hoʻokumu ʻia a me nā alloys titanium.ʻO ka lua, ma ke ʻano o ke kūpaʻa wela kiʻekiʻe a i ʻole ke kūpaʻa corrosion, ʻoi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe a i ʻole ke kūpaʻa corrosion, ʻaʻole hiki ke hoʻololi ʻia no ka 304 stainless steel.Eia kekahi, mai ka hoʻokaʻawale ʻana o ke kila kila, ʻo ke ʻano metallographic o ke kila kulika kūikawā he ʻano paʻa austenite metallographic.
No ka mea, ʻo kēia mea kila kila kūikawā he mea kiʻekiʻe-alloy, paʻakikī loa ke kaʻina hana.ʻO ka mea maʻamau, hiki i nā kānaka ke hilinaʻi wale i nā kaʻina hana kuʻuna e hana i kēia kila kila kūikawā, e like me ka infusion, forging, rolling a pēlā aku.
