ASTM SA210 GrAhe maitai waro-iti (C≤0.27%), kei roto ngā huānga pēnei i te konupūmā (Mn 0.93% mōrahi) me te silicon (Si 0.10-0.20%) hei whakarite i ngā āhuatanga miihini me te ngāwari o te tukatuka.

Ka whakapai ake te iti o te whanariki me te whākōkī (P≤0.035%, S≤0.035%) i te ātete ki te waikura i te pāmahana tiketike.

Mahi tino pai

Ātete pāmahana teitei: pāmahana mahi roa ≤450℃, wā poto tae atu ki te 480℃.

Peihana pēhanga teitei: he pai mō ngā paipa poiha pēhanga reo me te iti ≤5.88MPa.

Hototahi tukanga: ngāwari ki te whakarewa, ki te piko me te tukanga matao, e tika ana mō ngā pepa ngongo poiha, ngā pane me ētahi atu wāhanga.

Ngā paerewa pakari

Whakatutuki iASTM SA210 GrApaerewa, ā, ka paahitiaGB/T 3087, ASME me ētahi atu tiwhikete hei whakarite i te haumaru me te pono.

He pai rawa te paipa maitai kore-tuitui ASTM SA210 GrA mō ngā mara e whai ake nei:

Ahumahi kōhua: te pakitara wai kōhua, te whakamahana nui, te economizer me ētahi atu wāhanga matua.

Whakawhiti wera: ngā paipa whakamātao me te whakapūngao i roto i te umanga hinu.

Pūngao hiko: ngā paipa tuku mamaoa me ngā pūnaha āwhina o ngā tipu hiko wera.

Te whai huatanga o te utu: Ki te whakatauritea ki ngā paipa maitai koranu, ka whakaitihia e ngā paipa maitai waro ASTM SA210 GrA ngā utu hoko me te whakatutuki i ngā whakaritenga mahi.

Tuku pumau: Hei rauemi ngongo poiha whānui, he rawaka ngā taonga o te mākete, ā, he poto te huringa tuku.

Ka whakaratohia e mātou ngā ratonga tapahi ritenga, whakamātautau kore-whakangaro (UT/RT), pūrongo rauemi me ētahi atu ratonga mō ngā paipa maitai kore-hono ASTM SA210 GrA, ā, ka tautoko hoki i te tohatoha ratonga kawe taonga puta noa i te ao.

ASTM SA210 GrAKua noho te paipa maitai waro hei hua paerewa i roto i te mara o ngā kohua me ngā whakawhiti wera nā te mea he pumau tana mahi me te ōhanga. Mena kei te hiahia koe ki ngā tawhā hangarau, ki te hiahia rānei koe ki tētahi utu, whakapā mai ki tā mātou tīma ngaio!
