1. Hoʻohālikelike me ke kila kila austevitic

1)ʻoi aku ka ikaika o ka ikaika eʻoi aku ma mua o ka pālua o nā mea kila austenitic maʻamau, a he lawa ka mea momona a me ka paʻakikī i koiʻia no keʻano. ʻO ka mānoanoa o nā pahu mālama a iʻole nā'āpana i hanaʻia e nā mea kila fuplex i hoʻohanaʻia he 30-50% emi ma mua o ka hoʻemiʻana i nā kumukūʻai austenititic maʻamau.

2) He mea maikaʻi loa ia i ka paleʻana i ke kaumaha corrosion check ʻO ka mea kila maikaʻiʻoleʻo Duplex me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i keʻano o ka stylest He pilikia koʻikoʻiʻo Stroshertion i kahi pilikia kaulana i ka mea maʻamauʻo Austetenitic maʻamau 3)ʻO ka paleʻana o ka corrosione o ka mea maʻamau a me ka mea kūʻai akuʻo Duplex Duplex ma mua o nā mea kūʻai aku ma mua o ka mea kūʻai aku ma mua. Ma kekahi mau pāpāho, e like me ka acitic Actitic acid a me ke aupuni acid, hiki iā ia ke hoʻololi i ke kila kiʻekiʻe 4) He kūwaho maikaʻiʻo ia.

2. Hoʻohālikelikeʻia me nā mea kila Ferritic Stielless,ʻo nā pono o Dulex Stiinless Steel

1)ʻoi aku ka nui o nā mea i hoʻopiliʻia ma mua o nā mea kila ferritic ma mua,ʻoi aku ka paʻakikī ʻAʻole ia e like me ka nānāʻana i ka brittleness e like me ka mea kila ferritic.

2) Ma waho aʻe o ke kaumaha o ka paleʻana i ke kū'ēʻana,ʻoi aku ka maikaʻi o keʻano o ka'āina ma mua o ka mea kila ferritic.

3) Heʻoi aku ka maikaʻi o ka hanaʻana i ka hana a me keʻano anuanu ma mua o ka mea kila ferritic.

4) Heʻoi aku ka maikaʻi o ka hana welding eʻoi aku ma mua o ke kila stielless ferritic. ʻO ka maʻamau,ʻaʻole pono ke koiʻia ma mua o ka hoʻomahaʻana aʻaʻohe pono wela e pono e koiʻia ma hope o ka hoʻohanaʻana.

5)ʻO ka helu noi e pili ana i ka mea hoʻohana ma mua o ka mea kila stielless ferritic.
