QN1803 (304D) Pa'a kila kuhiliʻole

1.  wehewehe:

ʻO ka helu huahana hou QN1803 ʻo ia ka honua kiʻekiʻe kiʻekiʻe naikokene, kiʻekiʻe corrosion kū'ē, nickel-saving austenitic stainless steel.

Ma ke kumu o ka hōʻoia ʻana i ke kūpaʻa corrosion e like me 304 stainless steel, hoʻomaikaʻi ʻia ka ikaika o ka mea, a me ka mea.

ua ho'emi 'ia ke kumu kū'ai, 'o ia ke kumu kū'ai 'oi aku ka maika'i a 'oi aku ka ho'okūkū ma ka mākeke ma mua o 304 kila kila.

ʻO nā hiʻohiʻona hoʻolālā huahana hou: kiʻekiʻe nitrogen (≥2000ppm), kiʻekiʻe chromium (≥18%), nickel waena (~ 3.0%) a me ke keleawe kiʻekiʻe (≥1.5%).

Ma o ka papahana R&D kikohoʻe Thermo-Calc thermodynamic phase diagram software helu a me ka hoʻokolohua ʻikepili hoʻokolohua, hoʻoponopono i ka

ʻAʻole hoʻomaikaʻi wale nā ​​mea hoʻohuihui o kēlā me kēia māhele i ka pale ʻana o ka corrosion o ka huahana, akā hana pū nō hoʻi i ka ikaika hua o QN1803

ʻoi aku ma mua o 1.3 mau manawa ma mua o 304.

Loaʻa iā QN1803 nā hiʻohiʻona aʻe:

1) ʻoi aku ka lua o ka corrosion like PREN=Cr+3.3Mo+30N-Mn ma luna o 19.0, ʻoi aku ka liʻiliʻi o ka pale ʻana i ka corrosion e like me 304.

kila kohu ʻole.

2) ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion i loko o ka dilute hydrochloric acid, dilute sulfuric acid, acetic acid + paʻakai a me nā wahi ʻē aʻe.

304 kila kila.

3) ʻoi aku ka maikaʻi o ka pale ʻana i ka corrosion ma mua o 304 i ke kūlana hoʻohana maoli ma hope o ke kulou ʻana, ke kuʻi ʻana, ke kūlana paʻakikī a me nā hana anu.

4) ʻoi aku ka ikaika o ka hua ma mua o 1.3 mau manawa o 304 stainless steel, a he elongation ʻaʻole ia ma lalo o 45%. ʻAʻahu kūʻē a

ʻoi aku ka maikaʻi o ka hana luhi ma mua o 304 kila kila.

5) ka hana kuʻi ʻana maikaʻi, ʻoi aku ka ikaika ma hope o ke kuʻi ʻana ma mua o ka 304 stainless steel, a ʻo ka pale ʻana i ka corrosion.

e like me ke kila kila 304.

➢Nā puka a me nā puka makani paʻa: e like me nā hoʻoheheʻe papahele, nā hinges, nā ʻūlū, nā kaʻa paheʻe, a pēlā aku;

➢Nā paipu welded decorative: e like me nā pā, nā pale keʻena, nā escalators alapiʻi, nā puka makani palekana, etc.;

➢Nā paipu welded ʻoihana: e like me nā paipu kinoea, nā paipu hoʻoheheʻe ʻoihana;

➢Nā pahu pahu ʻoihana: e like me nā pahu reefer, nā hale kiaʻi desulfurization kinoea;

➢ Mea hana hānai: e like me ka pā hānai puaʻa, ka hoʻomāmona ʻana i ka pā lole pālua;

➢ Nā hale kaona: e like me nā hale kaʻa kaʻa, nā hale hoʻomaʻemaʻe.
