ASTM A516 vs A36, A572, Q355: Te Kōwhiri i te Pereti Rino Tika mō te Hanganga Hou

I te whanaketanga tonu o te umanga hanga whare, he mea tino nui ake i mua te whiriwhiri i te pereti maitai tika mō ngā kaupapa hanganga.Pereti maitai ASTM A516, e mōhiotia whānuitia ana ko te maitai waro e whakamahia ana i roto i ngā oko pēhanga, kei te piki haere te aro ki ngā tono hangahanga nā tōna kaha teitei, tōna āheinga whakarewa pai, me tōna mahi pāmahana iti. Engari he aha tōna whakataurite ki ētahi atu maitai hanganga e whakamahia whānuitia ana pēnei iNgā pereti maitai ASTM A36 , Ngā pereti maitai ASTM A572, me ngā pepa maitai Q355 o Haina?

Te Mahi me te Kaha o te Mīhini

Ko te kaha hua o te ASTM A516 (Ngā Tau 60-70) he 260–290 MPa te kaha kume tae atu ki te 550 MPa, me te kaha pai ki te pāmahana iti tae atu ki te -45°C. Hei whakataurite:

ASTM A36– Kaha whakaputa 250 MPa, kaha kume 400–550 MPa, mahi pāmahana iti whānui.

ASTM A572 (Kara.50)– Putanga 345 MPa, kume 450–620 MPa, he tino pai te āhua o te whakarewa me te pakari i te pāmahana iti.

Q355– Putanga 355 MPa, kume 470–630 MPa, e whakamahia whānuitia ana i roto i ngā kaupapa hanga Hainamana nā tōna kaha me tōna manawanui.

Nā tēnei ka tino pai te A516 mō ngā kurupae taumaha, ngā pereti pito piriti, me ngā wāhanga hanganga i ngā taiao makariri.

Ngā tono hanga noa

Rino Ngā tono
ASTM A516 Ngā pereti amo kawenga, ngā wāhanga piriti, ngā hanganga pāmahana-iti, ngā wāhanga tautoko-pēhanga
A36 Ngā kurupae paerewa, ngā pou, me ngā anga hanganga taketake
A572 Ngā kurupae whare teitei, ngā whare ahumahi, ngā piriti, ngā hanganga ātete-huarere
Q355 Ngā whare ahumahi, ngā whare putunga, ngā piriti, ngā pereti amo kawenga

Te Tukatuka me te Whakarewa

Nā te tino pai o te kaha whakarewa me te āhua hanga o te A516, ka taea te hanga hei pereti matotoru e mau ana i te kawenga, hei hononga whakarewa, me ngā wāhanga hanganga kua whakapakaritia. He ngāwari te tukatuka i te A36 engari kāore i te pai mō ngā mahi taumaha, roa rānei. He kaha teitei te A572 me te Q355 engari me āta whakahaere te whakarewa mō ngā wāhanga matotoru.

Te Kōwhiri i te Rino Tika

Mō ngā kaupapa hanga hou, ka nui haere te whakaaro o ngā kaihangarau ki te ASTM A516 ina hiahiatia te kaha me te mahi pāmahana iti mō ngā wāhanga hanganga. Mō ngā anga hanga whānui, he kōwhiringa utu-pai tonu te A36. I taua wā, ko te A572 me te Q355 te mea e pai ake ana mō ngā hanganga teitei, ngā piriti, me ngā whare ahumahi e tino hiahiatia ana te kaha me te manawanui.

I te mea e piki haere ana ngā paerewa hanga puta noa i te ao, he mea nui te mārama ki ngā rerekētanga ngawari i waenga i ngā momo maitai hei whakapai ake i te haumaru, te utu, me te mahi i roto i tētahi kaupapa.
