ASTM A588 Koki Tiaki Te Kaha Rawa

Ko te ASTM A588 he momo rino HSLA (te kaha teitei, te iti-koangi) e kapi ana i te iti o nga huānga koranu - parahi, chromium me te nickel. Ko enei huānga koranu he pai ake te whakapai ake i nga taonga A588 me te whakanui i ona tono. Tuatahi, ko te hanganga koranu ka taapiri atu i te kaha o te ira tuku ki te 50ksi me te kaha tensile ki te 70ksi. Tuarua, ki te ihirangi parahi, A588 he pai huru ha'iriiri ātete me te mahi mo te wa roa. Homai ona rawa matawhānui pai, A588 maitai koki rino he nui te whakamahi i roto i te piriti, te whare me etahi atu tono hanganga.

ASTM A588 HSLA koki maitai

He rite, he rereke ranei nga waewae o te koki maitai hanganga A588. Ka kitea e koe nga korero i te ripanga i raro nei. Mena ko to rekoata mo te rahi o te koki rino motuhake, imeera mai ki a maatau te rahi kua whakaritea ina rite ana to ota, nui atu ranei i to maatau iti.

Whakaahuatanga koki maitai A588:

Koeke maitai: A588.
Whakatakotoranga: ASTM A588.
Hangarau: wera hurihia.
Momo: rite & taurite.
Te roa: 6 m, 9 m, 12 m ranei mo to tono.
Koki rite:
- Rahi: 20 × 20 mm - 200 × 200 mm.
- Te Matotoru: 3 ki te 22 mm.
- Te roa: 6 m, 9 m, 12 m ranei mo to tono.
Koki taurite:
- Rahi: 20 × 30 ki te 90 mm × 250 mm.
- Te Matotoru: 3 ki te 15 mm.
- Te roa: 6 m, 9 m, 12 m ranei mo to tono.

Tuhipoka: Kei te waatea nga rahi koki maitai motuhake mena ka nui ake to ota i te iti rawa.

ASTM A588 maitai koki maitai me nga ahuatanga:

He iti te nui o te chromium, te parahi me te nickel.
He iti ake te taumaha/te kaha.
He ātete ki te waikura hau.
He pai mo te kaha nui me nga tono huarere.
Ka taea te tono te nui o te Alloy mo te kaupapa ahurei.
He iti ake te utu mo te wa roa.

He aha te rereketanga i waenga i te A588 ki te waro maitai A36?

Ko te ASTM A588 he rino hanga-iti te kaha teitei, ko te A36 he maitai waro noa.
Nā te rerekētanga o te ihirangi matū, he nui ake te whakamahi i te maitai koki A588 i te pae koki A36 ngawari.
Ko te koki rino A588 he pai mo nga taiao pirau kaore he maimoatanga mata e whakaiti ana i te utu.
A588 pae maitai koki me te tohu kaha tuku teitei ake i te A36, e taea ai te taumaha marama mo te ahua ano.
