He mīkini ʻo A283 Papa C me nā hana maʻamau e like me ka ʻoki ʻana, ka wili ʻana a me ka hoʻoheheʻe ʻana.
Noi:
A283 Gr C kila Hoʻohana nui ʻia e kūkulu i nā hale hana, hale kiaʻi uila uila kiʻekiʻe, nā Alahaka, nā kaʻa, ka umu ahi, nā ipu, nā moku, a pēlā aku, a hoʻohana ʻia hoʻi i nā koina hana no nā ʻenekini.
Nāʻano Dimensional o nā kila Ste A: ʻO ka mānoanoa pili no kēia mea papa A e like me ka mea i wehewehe ʻia ma ka ASTM A283 e hoʻomaka ana mai 6 mm a 50 mm. ʻO ka laulā maʻamau mai 600 mm a 2000 mm.
ʻO ka haku mele Kemika o nā A Steels: Hōʻike ʻo ASTM A283 i ka hoʻohui kemika o nā kila A papa ma lalo o:
Pakeneka kiʻekiʻe o Kalepona (C) ʻo ia 0.14
Pakeneka kiʻekiʻe o Silikone (Si) ʻo ia 0.4
Pakeneka kiʻekiʻe o Manganese (Mn) ʻo ia 0.9
Pakeneka kiʻekiʻe o Phosphorous (P) ʻo ia 0.035
Pakeneka kiʻekiʻe o Sulphur (S) ʻo ia 0.040
Ka pākēneka liʻiliʻi o Keleawe (Cu) ʻo ia 0.20
ʻO ke koena he hao (Fe) pākēneka a me nā impurities hiki ʻole ke hoʻowahāwahā ʻia
ʻO ASTM A285 kahi ʻano o ke kila kalapona maʻamau i manaʻo ʻia no nā mea hana hoʻoheheʻe i hoʻohui ʻia e like me ka paila, pahu wai waihona, nā mea kūʻai wela, a pēlā aku. , ka mea maʻamau e hāʻawiʻia ka ASTM A285 papa kila ma keʻano i'ōwiliʻia. hana ʻia e nā mea i pepehi ʻia, hoʻomake hapa ʻia, pale ʻia a pale ʻia paha i nā hana kila e like me ka makemake o nā mea hoʻohana hope.
Hiki ke hana ʻia ʻo ASTM A285 kila i loko o nā ʻano huahana kila, nā pā kila, ʻōwili hao, paipu kila, loaʻa iā ia ka wili maikaʻi no ka pono Weld fusion no nā pono kaomi puʻe, ua kaupalena ʻia kona max mānoanoa i 50mm i mea e ʻinikua ai i kāna waiwai mechanical.
Hoʻolālā ʻia ʻo ASTM A283 ma ke ʻano o ka papa kila kila no ke kumu kūkulu maʻamau, he haʻahaʻa a haʻahaʻa waena kēia kila, he 2 mau kaha kila (Papa C, Papa D). No ka papa kila i hana ʻia mai nā wili a i ʻole me ka mālama ʻole ʻana i ka wela, koi ʻia kahi hōʻike hou aʻe no ka hoʻomaha ʻana o ke koʻikoʻi, ma hope o ka hemo ʻana o ka wili kila, nānā ʻia, conditining, mālama ʻia ka wela ma mua o ka lawe ʻana. Hoʻohana wale ʻia ʻo ASTM A283 no ke kumu kūkulu, ʻoiai ʻo ASME SA283 / SA283M ke kila kila i hiki ke hoʻohana ʻia i ka paila a me ka hana kaomi puʻe. Availlable ASTM A283 hua kila e uhi ai i ka papa kila, ʻōwili hao, paipu kila, a me nā huahana kila kūkulu e like me nā ʻāpana kila, nā kaola, inā pono ʻoe e kūʻai i ka papa kila kila ASTM A283, kāhea iā mākou i kēia manawa.
