ʻO ASTM, i kapa ʻia ʻo ka American Society for Testing and Materials, he hui kūlana koʻikoʻi o ka honua i hoʻolaʻa ʻia i ka hoʻomohala ʻana a me ka hoʻolaha ʻana i nā kūlana no nā ʻoihana like ʻole. Hāʻawi kēia mau maʻamau i nā ʻano hoʻokolohua like ʻole, nā kikoʻī a me nā alakaʻi no ka ʻoihana US. Hoʻolālā ʻia kēia mau maʻamau e hōʻoia i ka maikaʻi, ka hana, a me ka palekana o nā huahana a me nā mea hana a e hoʻomaʻamaʻa i ka hana maʻalahi o ke kālepa honua.
ʻO ka ʻokoʻa a me ka uhi ʻana o nā kūlana ASTM he ākea a uhi ʻia i kahi ākea o nā kahua e pili ana, akā ʻaʻole i kaupalena ʻia, ʻepekema waiwai, ʻenekinia kūkulu hale, kemika, ʻenekinia uila, a me ka ʻenekini mīkini. i nā koi a me ke alakaʻi ʻana i ka wā hoʻolālā huahana, hana a hoʻohana.
ASTM A36/A36M:
ʻO nā kikoʻī maʻamau no ke kila e uhi ana i nā koi no ke kila kalapona kūkulu ʻia no ke kūkulu ʻana, hana ʻana, a me nā noi ʻenehana ʻē aʻe.
A36 Papa kilaNā Kūlana Hoʻokō
Hana maʻamau ASTM A36/A36M-03a, (e like me ke code ASME)
A36 pāhoʻohana
Pili kēia maʻamau i nā alahaka a me nā hale me nā hale i hoʻopaʻa ʻia, bolted a welded, a me nā ʻāpana kila kila maikaʻi kalapona, nā papa a me nā pahu. e ho'ēmi i ka waiwai o ka hua, ma muli o ke kalapona maʻamau, ka hana holoʻokoʻa o ka maikaʻi, ka ikaika, ka plasticity a me ka welding a me nā waiwai ʻē aʻe e loaʻa ai ka maikaʻi. match, ka mea i hoʻohana nui ʻia.
A36 pā kila kila haku mele mele:
C: ≤ 0.25, Si ≤ 0.40, Mn: ≤ 0.80-1.20, P ≤ 0.04, S: ≤ 0.05, Cu ≥ 0.20 (i ka wā e hoʻolako ai i ke kila keleawe).
Nā waiwai mīkini:
Ka ikaika hua: ≥250 .
Ka ikaika tensile: 400-550.
Elongation: ≥20.
ʻO ke kūlana aupuni a me ka mea A36 e like me Q235.
Ka manawa hoʻouna: Jun-24-2024
