ʻO ke kumumanaʻo, nā ʻano a me nā kūlana hana o 304 kaha kila kila kiʻekiʻe

304ʻO ke kila kila kila kiʻekiʻe he huahana pololei loa, a he mau kūlana paʻa loa no ka ʻōlinolino, ka ʻoʻoleʻa, nā waiwai mechanical, ka paʻakikī, ka hoʻomanawanui pololei a me nā ʻōkuhi ʻē aʻe o ka hōʻike, no laila ua lilo ia i alakaʻi i nā kila kila.

1. Ke kumumanaʻo oʻāpana kila kila pololei

ʻO ka maʻamau, kapa mākou i ke kila kila ʻōwili anu me ke kiko o 600-2100N/mm2 a me ka mānoanoa o 0.03-1.5mm he kila kila ikaika kiʻekiʻe. He mea kūikawā loa ka hana manawa.

ʻO ke kumumanaʻo, nā ʻano a me nā kūlana hana o 304 kaha kila kila kiʻekiʻe

2. Nā ʻano o304 kila kila pololei

Ma muli o kēia huahana i ke kahua o ka loea, ma o kāna mau palena a me nā kūlana hana, hiki iā mākou ke hoʻomaopopo i kona mau ʻano ma nā ʻano aʻe:

1) ʻO ka laulā ma lalo o 600mm;

2) ʻO ka mānoanoa o ka hoʻomanawanui ʻana he ± 0.001mm, a ʻo ka laulā o ka hoʻomanawanui ʻana he ± 0.1mm.

3) Hiki i ka maikaʻi o ka ʻili o ka huahana ke hoʻokō i nā pono o nā hanana like ʻole, e like me ka ʻili 2B maʻamau, ka ʻili BA a me ka ʻili kūikawā.

4) Loaʻa iā ia nā waiwai mechanical kiʻekiʻe, a hiki ke hoʻopili ʻia ke koʻikoʻi a me ka ikaika kūpono e like me nā pono o nā mea kūʻai aku.

5) ʻAno like ka nui o ka palaoa. Ke hoʻomoʻa piha ʻia ka huahana, pono e kāohi ʻia ka nui o ka palaoa ma 7.0-9.0. I ka manawa like, ua kaulike pū ka hana ikaika, a pono e kāohi ʻia ka loli o ka paʻakikī ma waena o ±5-10Hv.

6) Eia kekahi, he mau koi kiʻekiʻe ko nā ʻāpana kila pololei 304 no ka pololei a me ka maikaʻi o ka lihi.

3. Nā kūlana hana no nā ʻāpana kila

1) ASTM A666: Uhi kēia kūlana i nā mea ʻāpana kila kila austenitic, me ke ʻano 304, a kuhikuhi i nā koi no ka haku mele kemika, nā waiwai mechanical, nā ana, a me nā hoʻomanawanui.

2) EN 10088: Hāʻawi kēia kūlana ʻEulopa i nā kūlana hoʻouna loea no ke kaula kila kila, me ka papa 1.4301, e kūlike ana me AISI 304. Uhi ia i nā ana, nā ʻae ʻana, nā kūlana o ka ʻili, a me nā waiwai mechanical.

3) JIS G4305: Hōʻike kēia kūlana Kepanī i nā kikoʻī o ke kila kila kila i ʻōwili anu ʻia, me ke ʻano SUS304, kahi like me AISI 304. Uhi ia i ka haku mele kemika, nā waiwai mechanical, nā ana, a me nā hoʻomanawanui.

ʻOiaʻiʻo, loaʻa i kēlā me kēia mea hana kāna mau kūlana hana ponoʻī. E hoʻokumu nā ʻoihana hana he nui i kā lākou mau kūlana hana ponoʻī e pili ana i nā kūlana kila kila i ʻōwili anu ʻia a i ʻole e like me nā pono o ka mea kūʻai aku. Eia nō naʻe, manaʻo ka nui o nā mea hana he nui nā koi kiʻekiʻe o ka huahana ma ke ʻano ʻē, hiki ke hoʻokō i nā pono o nā mea kūʻai aku like ʻole.
