316 pepa kila kuhili ʻoleLoaʻa iā ia nā hiʻohiʻona o Ferrite a me Austenite, a me nā mana maikaʻi o ke kūpaʻa koʻikoʻi o ka chloride a me ke kūpaʻa corrod.ʻO 2205 he kila duplex, aia he 21% Cr, 2.5% Mo a me 4.5% Ni-N.ʻO kona ikaika piʻo ʻelua ʻelua ma mua o Austnite.Hiki i ka hiki ke ho'ēmi i ke kaumaha o nā huahana i ka hoʻolālā.ʻOi aku ka maikaʻi ma mua o 317L kila kila.
No ka mea316 pepa kila satin ʻole i poni ʻiahe nui ka Cr a me Mo, no laila hiki iā ia ke anti-pitting.Hiki i ka Duplex stainless steel ke hōʻoiaʻiʻo he kiʻekiʻe ka ikaika o ke kila o ke kūpaʻa paʻi a me ka pale ʻana i ka corrod a me ka ikaika mechanical.
316 kila kuhiliʻole ka hana mechanical, corrod pale a me ka maikai weldability.Hoʻohana ʻia ia i ka ʻaila a me ka ʻoihana kinoea maoli, ka moana, ka ʻoihana kemika a me nā ʻoihana ʻē aʻe.I kēia manawa, hoʻohana ʻia ka ʻaila a me ka ʻoihana kinoea ma mua o 850km mau ʻaila aila i hana ʻia e nā kila stainless duplex.ʻO ka hapa nui o kēia mau kila duplex he 316L stainless seamless steel pipes (a ʻo nā ʻāpana he S31803 duplex stainless steel pipes a me 2507 duplex stainless steel pipes).No ka mea he kiʻekiʻe ka corrosivity o ke kinoea maoli, ʻo nā paipu piʻi kiʻekiʻe e mabe e 316 mau paipu kila kila.
Hiki ke hoʻohana ʻia ka 316 stainless steel i kēia mau ʻano: neutral chloride environment, hoʻomaʻemaʻe ʻoihana, ʻoihana aila, ʻoihana kemika, petroleum a me ka ʻoihana kinoea maoli, pulp a me ka pepa ʻoihana, ʻoihana fertilizer, ʻoihana urea, ʻoihana phosphate fertilizer, kai kai, ikehu a me ke kaiapuni. ʻoihana pale, ʻoihana māmā a me ka ʻoihana meaʻai, nā meaʻai a me nā lako ʻoihana lāʻau.
ʻO 316 ke kila kila maikaʻi ka pale ʻana i ka corrod no ka mea he kiʻiʻoniʻoni passivation kona ʻili i loko o ka oxygen paʻa, no laila kaulana ʻo 316 stailess steel.
