ʻŌwili kila kila Duplex

E like me ka mea i ʻōlelo ʻia ma luna, ʻoi aku ka maikaʻi o ka hana ʻana o Duplex ma mua o nā ʻano kila pākahi i loaʻa i loko o kāna microstructure. ʻOi aku ka maikaʻi o ka ʻōlelo ʻana, ʻo ka hui pū ʻana o nā ʻano maikaʻi e hele mai ana mai nā mea austenite a me ferrite e hāʻawi i kahi hopena holoʻokoʻa maikaʻi aʻe no ka nui o nā kūlana hana like ʻole.

Nā waiwai anti-corrosion - Nui loa ka hopena o ka molybdenum, chromium, a me ka nitrogen i ke kūpaʻa ʻana i ka pala o nā Duplex alloys. Hiki i kekahi mau Duplex alloys ke hoʻokūkū a ʻoi aku ma mua o ka hana anti-corrosion o nā papa austenitic kaulana e like me 304 a me 316. He kūpono loa lākou e kūʻē i ka crevice a me ka pitting corrosion.

ʻO ka haki ʻana o ka palaho koʻikoʻi - hele mai ka SSC ma muli o kekahi mau kumu lewa - ʻo ka mahana a me ka haʻahaʻa ka mea i ʻike nui ʻia. Hoʻohui wale ke koʻikoʻi tensile i ka pilikia. He maʻalahi loa nā papa austenitic maʻamau i ka haki ʻana o ka palaho koʻikoʻi - ʻAʻole ke kila kila Duplex.

Paʻakikī - ʻOi aku ka paʻakikī o Duplex ma mua o nā kila ferritic - ʻoiai ma nā mahana haʻahaʻa ʻoiai ʻaʻole ia e kūlike me ka hana o nā māka austenitic ma kēia ʻano.

Ikaika - Hiki i nā mea hoʻohuihui Duplex ke ʻoi aku ka ikaika a hiki i ʻelua manawa ma mua o nā ʻano austenitic a me ferritic. ʻOi aku ka ikaika o ke ʻano o ka paʻa ʻana o ka metala me ka emi ʻana o ka mānoanoa he mea nui loa ia no ka hoʻemi ʻana i nā pae kaumaha.
