DUPLEX STAINLESS STEEL KE ANO A ME KE KUMU

DUPLEX STAINLESS STEEL KE ANO A ME KE KUMU

• Lean Duplex SS - nickel haʻahaʻa a ʻaʻohe molybdenum - 2101, 2102, 2202, 2304
• Duplex SS – nickel kiʻekiʻe a me ka molybdenum - 2205, 2003, 2404
• Super Duplex – 25Chromium a me ka nickel kiʻekiʻe a me ka molybdenum "hoʻohui" - 2507, 255 a me Z100
•Hyper Duplex – ʻOi aku ka Cr, Ni, Mo a me N – 2707

Nā Pono Mechanical:
• Ua ʻoi aku ka ʻoi aku o ka ikaika o ka hoʻohua ʻana o nā kila kila ʻole Duplex o kā lākou mau māka austenitic.
• 'O kēia ka mea hiki i nā mea ho'olālā lako ke ho'ohana i nā mea ana i nā mea hana moku!

ʻO ke kila kila ʻole Duplex:
1. Hoʻohālikelike ʻia me ka austenitic stainless steel
1) ʻOi aku ka ikaika o ka hoʻoulu ʻana ma mua o ʻelua mau kiʻekiʻe ma mua o ke kila kila austenitic maʻamau, a ua lawa ka paʻakikī palaki e pono ai no ka hana ʻana. ʻO ka mānoanoa o ka pahu a i ʻole ka ipu kaomi i hana ʻia me ka duplex stainless steel ʻo 30-50% ka haʻahaʻa ma mua o ka mea maʻamau o ka austenitic stainless steel i hoʻohana mau ʻia, he mea maikaʻi ia e hōʻemi i ke kumukūʻai.
2) He kūpaʻa maikaʻi loa ia i ka ʻāʻī ʻana o ke koʻikoʻi, ʻoi aku ka nui o ke kaiapuni i loaʻa i nā ion chloride, ʻoiai ʻo ka duplex alloy me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i ʻoi aku ke kūʻē ʻana i ke koʻikoʻi ma mua o ka austenitic stainless steel. He pilikia koʻikoʻi i paʻakikī ke hoʻoponopono ʻana i ke kila kila austenitic maʻamau.
3) ʻO ka 2205 duplex stainless steel maʻamau i hoʻohana ʻia i nā media he ʻoi aku ka maikaʻi o ka corrosion ma mua o ka 316L austenitic stainless steel maʻamau, aʻo ka super duplex stainless steel he kiʻekiʻe ke kūpaʻa kino. I kekahi mau media, e like me ka acetic acid a me ka formic acid. Hiki iā ia ke hoʻololi i nā kila kila austenitic kiʻekiʻe a hiki i nā mea hoʻoheheʻe kū i ka corrosion.
4) He kū'ē maikaʻi i ka corrosion kūloko. Ke hoʻohālikelike ʻia me ka austenitic stainless steel me ka mea like ʻole, ʻoi aku ka maikaʻi o ke kūpaʻa ʻana a me ke kūpaʻa luhi corrosion ma mua o ka austenitic stainless steel.
5) ʻO ka austenitic stainless steel he haʻahaʻa haʻahaʻa o ka hoʻonui laina a kokoke i ke kila kalapona. He kūpono ia no ka hoʻopili ʻana me ke kila kalapona a he koʻikoʻi koʻikoʻi ka ʻenekinia, e like me ka hana ʻana i nā papa hoʻohui a i ʻole nā ​​linings.

2. Hoʻohālikelike ʻia me ke kila kila ferritic, ʻo nā mea maikaʻi o ka duplex stainless steel penei:
1) ʻOi aku ka kiʻekiʻe o nā waiwai mīkini piha ma mua o ka ferritic stainless steel, ʻoi aku ka paʻakikī palaki. ʻAʻole maʻalahi i ka brittleness e like me ka ferritic stainless steel.
2) Ma waho aʻe o ke koʻikoʻi o ka corrosion resistance, ʻoi aku ka maikaʻi o ke kūʻē ʻana o ka corrosion kūloko ma mua o ka ferritic stainless steel.
3) ʻOi aku ka maikaʻi o ka hana ʻana o ke kaʻina hana anu a me ka hana anuanu ma mua o ke kila stainless ferritic.
4) ʻOi aku ka maikaʻi o ka hana kuʻi ʻana ma mua o ka ferritic stainless steel. ʻO ka maʻamau, ʻaʻole koi ʻia ka mālama wela ma hope o ka hoʻomaʻamaʻa ʻana me ka ʻole o ka wili.
5) ʻOi aku ka laulā o ka noi ma mua o ka ferritic stainless steel.

Palapala noiMa muli o ka ikaika kiʻekiʻe o ke kila duplex, mālama ia i nā mea, e like me ka hoʻemi ʻana i ka mānoanoa o ka pā o ka paipu. ʻO ka hoʻohana ʻana o SAF2205 a me SAF2507W ma ke ʻano he laʻana. Ua kūpono ʻo SAF2205 no ka hoʻohana ʻana i nā kaiapuni i loko o ka chlorine a ua kūpono ia no ka hoʻohana ʻana i ka hoʻomaʻemaʻe a i ʻole nā ​​​​mea hana ʻē aʻe i hui pū ʻia me ka chloride. He kūpono loa ka SAF 2205 no ka hoʻohana ʻana i nā mea hoʻololi wela i loaʻa i ka wai chlorine a i ʻole ka wai paʻakai ma ke ʻano he mea hoʻoluʻu. He kūpono nō hoʻi ka mea no ka dilute sulfuric acid solutions a me nā ʻakika organik maʻemaʻe a me nā hui ʻana o ia mea. E like me: nā paipu aila i loko o ka ʻoihana aila a me ke kinoea: ka hoʻomaʻemaʻe ʻana i ka aila maʻemaʻe i loko o nā hale hoʻomaʻemaʻe, ka hoʻomaʻemaʻe ʻana i nā kinoea i loko o ka sulfur, nā lako mālama wai ʻino; nā ʻōnaehana hoʻoluʻu me ka hoʻohana ʻana i ka wai paʻakai a i ʻole ka wai chlorine.

Ke ho'āʻo waiwai:
ʻO SAKY STEEL e hōʻoia i ka hele ʻana o kā mākou mau mea āpau i nā hoʻokolohua koʻikoʻi ma mua o ka hoʻouna ʻana iā lākou i kā mākou mea kūʻai.

• Hoao Mechanical E like me Tensile o Wahi
• Hoao paakiki
• Nānā Kemika - Spectro Analysis
• ʻIke Mea Pono - PMI Testing
• Ho'āʻo palahalaha
• Micro a me MacroTest
• Ho'āʻo Kūʻē Pitting
• Ho'āʻo Flaring
• Ho'āʻo Intergranular Corrosion (IGC).

HOPE NINAU.
