Ma ke'ōnaehana hana o ka hana, he mau kī koho huluhulu wela, he mau mea maʻamau nā kumu kumu, a me ko lākouʻokoʻa o nā hoʻohālike a me nā hana hana maʻamau o ka hoʻomohalaʻana i nā kaʻina hana ma lalo o nāʻaoʻao kūkulu mua. ʻO nā hiʻohiʻona likeʻole o nā cetel wela e pāʻani ai i kahi kūlana o ka hanaʻana i nā kahua o ka kūkuluʻana, nā kaʻa, etc. me ka ikehu. ʻO ka mea e pili ana i ka nānāʻana i nā hiʻohiʻona koho balota wela wela me ke koi kiʻekiʻe a me ko lākou mau mea kiʻekiʻe.
ʻO ka ikaika nui: Q235B a me SS400
ʻO Q235B ka mea maʻamau i hoʻohana pinepineʻia i nā kila haʻahaʻa haʻahaʻa-carbon i china, me kahi kiko'ī o ka carbon e pili ana i ka 0.12%, a loaʻa i nā waiwai momona a me nā waiwai maikaʻi. ʻO kona ikaika e hāʻawiʻia he ≥2360MP a ua nui loa i hoʻohanaʻia i loko o ka hale kūkulu hale, kākoʻoʻia ke alahaka a me nā'āpana maʻamau. I kaʻoihana kūkulu,ʻo I-BAMS, nā mea hele mai nā kilokilo a me nā kila i hanaʻia i ka nui o nā mea kūʻai aku ma mua o 60%.
ʻO SS400 kahi mea i hoʻohanaʻia i loko o ka carbon i hoʻohanaʻia me ka ikaika e like me Q235b, akāʻo ka mana o nā sulfurus a me nā phospoprus a me nā phosphorus a me nā photspoprus a me nā phospopor Ma ke kahua o nā moku moku Schoolbuilding,ʻo SS400 mau'āpana wela i hoʻohana pinepineʻia no nā'āpana hill. ʻOi aku ka maikaʻi o kāna paleʻana o ke kai moana
Nā Kūlana Nui: Q345B a me Q960
ʻO Q345B kahi kiʻi kiʻekiʻe haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa me 1.0% -1.1.6% ma luna o 345mpa. Hoʻohālikelike me Q235B, ua hoʻonuiʻia kona ikaika e ka 50%,ʻoiai ke mālama nei i ka weloltability maikaʻi. Ma ka huakaʻi hele kaʻa,ʻo nā kāʻei pahu pahu i hanaʻia e nā collat collal wela i hiki ke hōʻemi i ke kaupaonaʻana e ka 20%, e hōʻemi nui ana i nā kumukūʻaiʻenehana. I 2023, e hoʻopau houʻia ka hanaʻana o ke alahaka Tomestic ma mua o 12 miliona mau kāleka wela o Q345B
E like me keʻano he mea koho maʻamau o Ultra-High Reels Ma ke kahua o ka mīkiniʻenehana,ʻo ka mānoanoa o ka lima crane i hanaʻia e ka 6mm e hoʻonuiʻia e nā excavator a me nā cranes.
Nā Kūlana Kūʻai Kūʻai: SPHC a me SAP340
ʻO Sphc kahi huahana kiʻekiʻe-pale ma waena o nā kāʻei haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa-colleloka. Ma kaʻaeʻana i ke kaʻina holoʻana e kāohi ai i ka nui o ka palaoa, ua hiki i ka Ellingation iʻoi aku ma mua o 30%. Ma ka hale hana home home, i hoʻohanaʻia nā papa wela wela i nā mea hana stirijitory. ʻO kona hana kiʻi hohonu e hōʻoia ana i ka helu pono o ka pae kiʻekiʻe o keʻano he nui o keʻano he nui iʻoi aku ma mua o 98%. I 2024, kaʻaiʻana o nā papa wela o SPHC i loko o ka hale kūʻai home home e hoʻonuiʻia e ka 15% makahiki i ka makahiki 3.2 miliona mau makahiki.
E like me kahi kila kila Automotive Ma ka hanaʻana o kaʻoihana pāʻoihanaʻoi aku ka nui o kaʻoihana,ʻo Saph340 I 2023, ka helu o nā'āpana wela o kēiaʻano i hoʻohanaʻia ma nā wahiʻoihana hou i loaʻa i ka 70% o nā'āpana pāʻoihana.
| Hōʻailona | Hāʻawi i ka ikaika (MPA) | Elongation (%) | Nā hiʻohiʻona palapala maʻamau |
| Q235B | ≥235 | ≥26 | Kūkulu hale, nā mīkini hoʻokahe |
| Q345B | ≥345 | ≥21 | ʻO nā alahaka, nā moku kū |

Inā makemakeʻoe eʻike hou aku e pili ana i ka kila, eʻoluʻolu e hoʻomau aʻike paha iā mākou.
