Hiki ke hoʻokaʻawale ʻia ke poʻo lāʻau i ka hoʻolei ʻana i ʻelua ʻāpana a me ka forging ʻehā mau ʻāpana.
E kaʻana kēia ʻatikala iā ʻoe i ke kaʻina hana o ka forging ʻehā mau ʻāpana.
ʻO ka mea mua, hoʻolauna i nā mea hana metala a ko mākou poʻo lāʻau kolepa e hoʻohana ai.
1. Ka haʻahaʻa haʻahaʻa a me ka ikaika kikoʻī kiʻekiʻe
2. Kūpaʻa kūpaʻa ikaika
3. Kūpaʻa wela ikaika
4. ʻO ke kūpaʻa wela haʻahaʻa ikaika
5. Ka ikaika kiʻekiʻe a hāʻawi i ka ikaika
| Helu pono | Mea hoʻohui | Hiʻona |
| GR2 | Fe0.2, C0.08, N0.03, O0.25, H0.015 | Hoʻohana kiʻekiʻe e hana i nā paipu. |
| GR3 | Fe0.2, C0.08, N0.03, O0.35, H0.015 | ʻO ka ikaika ʻoi aku ma mua o GR2, plasticity haʻahaʻa haʻahaʻa i hoʻohana nui ʻia no ka paipu hoʻohui poepoe. |
| GR4 | Fe0.2, C0.08, N0.03, O0.35, H0.015 | ʻO ka paʻakikī kiʻekiʻe loa ma waena o ka titanium maʻemaʻe ʻoihana, hoʻohana ʻia e hana i ka lalo a me ka pāpale aliʻi |
| TC4 / GR5 | AL6 ， V4 ， Fe0.3, Si0.15, C0.1, N0.05, O0.2, H0.01 | ʻO ka ikaika kiʻekiʻe, hoʻohana ʻia no ka maka |
| TI2041 | AL4 ， V20 ， Sn1 | Hoʻonui i ka paʻakikī e ka mālama ʻana i ka wela, ka ikaika kiʻekiʻe a me ka lahilahi maikaʻi |
1. Martensitic mea kila kila (Mākēneki!)
ʻO ke kila kila nona nā pono mechanical e hiki ke hoʻoponopono ʻia e ka mālama wela.
He papa kēia o nā kila kila paʻakikī.
ʻOi aku ka kiʻekiʻe o ka paʻakikī ma hope o ke kinai ʻana, a ʻokoʻa nā mahana wela like ʻole i hoʻohui ʻia o ka ikaika a me ka paʻakikī.
Nā mea nui: SUS430, SUS431, SUS630 / S.S17-4, a pēlā aku
2. ʻO Austenitic mea kila kila (Non-magnet!)
He hale paʻa kona ma lalo o ka mahana maʻamau, a ʻaʻole hiki ke hoʻololi i ka paʻakikī ma o ka mālama ʻana i ka wela. He kiʻekiʻe paʻakikī kona a me ka plasticity, akā haʻahaʻa ka ikaika, a hiki ke hoʻoikaika wale ʻia ma o ka hana anuanu.
Nā mea nui: SUS202, SUS303, SUS304, SUS316 a pēlā aku
3. Hoʻohui kila kuhiliʻole (Mākēneki!)
ʻO ke ʻelemakule e pili ana i ke kaʻina hana hoʻomehana e mālama i kona ʻano, ka nui, ka hana a me nā loli me ka manawa ma hope o ke kinai ʻana i ke ana wela a i ʻole ma hope o kekahi kekelē hana anuanu i ke kau ʻana i kahi mahana kiʻekiʻe a i ʻole ka mahana o ka lumi.
Nā mea nui: SUS450, SUS455, SUS460, a pēlā aku

ʻĀpana Pono
ʻOkiʻoki ka mīkini hana i kēia mau papa kila a i ʻole titanium i mau ʻāpana lōʻihi, a laila ʻokiʻoki i kēia mau ʻāpana lōʻihi i loko o kekahi mau ʻāpana hao o ka nui kūpono.
Weld welau nā pono āpau e pono ai, a laila hoʻopili iā lākou, a a forged 4-ʻāpana wahā Hana poʻo poʻo ua hana ʻia.
