1. Kupu Whakataki: Taumata ōrite, DNA rerekē
I roto i ngā whakatakotoranga maitai hanganga,S355J2Hhe whakaritenga noa mōngā wāhanga tuwheraHeoi, e kitea ana i raro i ngā paerewa hangahanga e rua:EN 10210meEN 10219Ahakoa te tinihanga a te tohu "S355J2H" i ngā kaihoko kia whakaaro he ōrite rāua, he rerekē rawa te huarahi hanga—ā, nō reira, te mahi hoki.
E whakataurite ana tēnei tuhinga i te EN 10210 S355J2H (Whakaoti Wera) ki te EN 10219 S355J2H (Whakaahua Matao) hei whakamārama i ō rātou rerekētanga ā-pūkaha, ngā āhuatanga tirohanga, me te pai o te whakamahinga.
2. Te Rerekētanga Matua: Te Tukanga Hanga
EN 10210 - Kua oti te whakakī (S355J2H)
Ko ngā wāhanga i raro i te EN 10210 ka hangaia i ngā pāmahana teitei (i te nuinga o te wā kei runga ake i te pāmahana whakakōkī anō). Mā tēnei tukanga "Hot Finished" ka whakamama i ngā ahotea o roto i hangaia i te wā e hanga ana. I roto i te EN 10210, ka hangaia te S355J2H mā te ara Stress Relieved (whakamahana i raro i te 850°C) mā te ara Fully Normalized rānei (whakamahana i runga ake i te ~850°C hei tautuhi anō i te hanganga o te witi). Ka tukuna e ngā ngongo Fully Normalized te ngāwari me te ōritetanga pai rawa atu.
EN 10219 - Hangaia Matao (S355J2H)
Ko ngā wāhanga i raro i te EN 10219 ka hangaia i te pāmahana rūma mai i te koiri maitai, i te pereti rānei. Ka pikohia te maitai, kātahi ka whakarewahia (ko te tikanga he ERW, he SAW rānei). Mā tēnei mahi makariri ka whakapakeketia te maitai, inā koa i ngā piko me ngā kokonga, ka mau tonu ngā ahotea toenga teitei.
3. Whakataurite i ngā Whakatakotoranga Hangarau (S355J2H)
Ahakoa he ōrite ngā rohe hanganga matū, ka rerekē te mahi ā-pūkaha me ngā manawanui e whakaaetia ana nā te tikanga hanga.
| Taonga | EN 10210-1(Kua Oti te Wera) | EN 10219-1(I hangaia mātao) |
| Te pāmahana hanga | I runga ake i te Whakakoi Anō (Wera) | Āhuarangi / Mahana Rūma (Mātao) |
| Te Kaha Hua (ReH) (T ≤ 16mm) | ≥ 355 MPa | ≥ 355 MPa |
| Kaha Kume (Rm) (3mm ≤ T ≤ 40mm) | 470 – 630 MPa | 470 – 630 MPa *(Tuhipoka: Kei roto i ngā whakaritenga EN10219 te 490-630 mō te T<3mm)* |
| Te whakaroa | Iti rawa 22% (He ngāwari ake nā te maimoatanga wera) | 20% iti rawa (He iti iho nā te whakapakeketanga o te mahi) |
| Te Pakari Pānga (KV) | 27J @ -20°C | 27J @ -20°C |
| Te ahotea toenga | Iti (Ka whakamamahia e te wera) | Teitei (Kua maukati i roto i te hanganga) |
| Te Pūtoro Koki (SHS/RHS) | < 2T (Kia pūmau ake, kia koi ake) | 1.6T ~ 3.6T (Radius nui ake) |
4. Ngā Rerekētanga Tirohanga me ngā Ahuhanga
Te Pānga "Pīni" (Taumahatanga Toenga): He āhua noa iho tō ngā wāhanga matao (EN 10219) ki te "hoki whakamuri" ki te "pīni" rānei ina tapahia nā te kaha toenga kua rongoatia. Ka noho pumau tonu te āhua o ngā wāhanga kua oti te whakamahana (EN 10210) i muri i te tapahi.
Ngā Kokonga: Mō ngā Wāhanga Tapawhā me te Tapawhā Ātea (SHS/RHS), ka taea e te EN 10219 te whakawhāiti i te whānui o te kokonga ki te 3.6 ngā wā o te matotoru o te pakitara (T), ka hua ake he kokonga porowhita rawa. Ko ngā wāhanga EN 10210 kua oti wera (ina koa ko ngā wāhanga kua whakaritea) ka eke ki te whānui koi ake (he maha ngā wā < 2T), ka puta he mata papatahi nui ake.
Matotoru o te Pakitara: Ko te tikanga, he pakupaku ake ngā āheinga matotoru o te EN 10210 ki te whakaritea ki te EN 10219.
5. Ko tēhea te mea me whiriwhiri e koe?
KōwhiriEN 10210-1 S355J2Hmēnā:
Ngā tono hanganga matua: Ngā piriti, ngā pūma kerēni, ngā rohe rū whenua, ngā papaaho tai moana rānei.
Ātete Ngenge Nui: Ko te whakarewa, ko te kawenga hihiri rānei, me iti te ahotea toenga o te rauemi hei ārai i te tīmatanga o te kapiti.
Ngā hiahia ataahua/tika: Me whai kokonga piripono, me te tika e taea te matapae mō ngā mahi rino e kitea ana i roto i te hoahoanga.
Te hanga wera: Ki te whakaaro koe ki te piko wera nui, ki te hanga pito rānei, ka pai ake te matapae i te whanonga o te rauemi kua whakaritea.
Kōwhiria te EN 10219-1 S355J2H mēnā:
Te whai huatanga o te utu: He iti ake te utu o te hanga matao, ā, he mama ake mō ia rahinga ingoa.
Hanganga whānui: Ngā whare papa-iti, ngā papa o runga, ngā pou taiapa, ngā taputapu ahuwhenua rānei, ina kore te ahotea toenga iti e raru ai te hinga.
Te Wātea: Koinei te ngongo "paerewa" tino noa e kitea ana i ngā toa whānui o te ao.
6. He Whakatūpato Nui mō "S355J2H"
Kia tūpato: Kāore i te ōrite te hanganga o ngā ngongo EN 10210 S355J2H katoa.
Ka taea e ngā kaihanga te whakaputa i ngā ngongo EN 10210 mā te whakamahi i te "Stress Relieved" me te "Fully Normalized" rānei.
Paerewa S355J2H (Whakaitihia te ahotea): E tutuki ana i te paerewa engari he iti te ahotea. He iti ake te utu.
S355NH (Kua Whakaōritea): He momo motuhake i raro i te EN 10210 e hiahia ana kia whakaōritea katoatia (mahana teitei). Koinei te hua kounga teitei mō te whakarewa.
Mena kei te hiahia koe i te ngāwari teitei rawa atu, me te kore ahotea toenga mō te whakarewa, whakapai ake i tō whakaritenga ki te EN 10210 S355NH kaua ki te J2H paerewa.
