He aha ka ASTM A519 Grade 1020?

ASTM A519he paipu kila maʻemaʻe no nā hana mechanical me ke anawaena o waho ʻaʻole iʻoi aku ma mua o 12 3/4 iniha (325 mm).

Papa 1020, Papa MT 1020, aPapa MT X 1020ʻekolu o nā papa, he paipu kila kalapona.

Ke Kaʻina Hana Hana o ASTM A519

E hana ʻia ʻo ASTM A519 me ka hoʻohana ʻana i kahi kaʻina hana ʻole, ʻo ia ka huahana tubular me ka ʻole o nā seam welded.

Hana ʻia nā paipu kila seamless e ka hana wela.Inā makemake ʻia, hiki ke hoʻohana ʻia ka huahana wela e loaʻa ke ʻano, ka nui, a me nā waiwai i makemake ʻia.

Loaʻa i ka ASTM A519 nā hiʻohiʻona poepoe, ʻāhāhā, ʻāpana ʻehā, a i ʻole nā mea kūikawā ʻē aʻe.

Hoʻolaha ʻo Botop Steel i nā paipu kila poepoe a hiki iā ia ke hana i nā ʻano ma ke noi.
