1. Hōʻikeʻike
I waena o nā mea kanu maloʻo, ʻO A2 vs O1 O1 Sweel Steel i noho i nā kūlana koʻikoʻi ma ka AISI / SEE a me Astm A681 Standards.
ʻOiai e kaʻana aku nei i kahi papa e like me nā mea hana hana hana maloʻo, ʻO kā lākou mea e hoʻokaʻawale i nā mīkini paʻakikī-ea-paʻakikī-paʻakikī-paʻakikī, Hana, a me nā kūpono kūpono.
Nā mea hana hāmeʻa ua hanaʻia no nā pale pale, hālulu, a me nāʻano kūpono o ka dimensional-ʻano e pono ai eʻoki, hana, a me nā mea hana i nā kūlana hana i nā kūlanaʻoihana.
Hōʻike kēiaʻatikala i kahi hoʻohālikelike kiko'ī ma waena o A2 a me O1 mau kāpili hāmeʻa,
e nānā ana i kā lākou huiʻana, ʻO ka mālama wela, Nā Pīkuhi Propertinies, markinpalibility, Ke kū'ē neiʻo Corrosionion, a me nā hihia e hoʻohana ai i nāʻoihana e alakaʻi i nā poʻe loea e hana i nā koho i hōʻikeʻia.
2. He aha ka mea hana mīkini mīkini mīkini?
A2 kahi kila hana i ka a-hui o Astm A681, loaʻa iā ia ke "A" hoʻolālā e ka paʻakikī i ka lewa ma mua o ka aila a wai paha.
Me he ʻO ke kila anuanu, e like me ka hanaʻana i nā hana a me ka machining ma lalo o kāna mahana hou, Ke hāʻawi nei i ka mana o ka DIMEBIONALL o ka hoʻokele a me ka hoʻopauʻana i nā mea i hoʻohālikelikeʻia i nā alloys wela.
