2. Paipa Rino EN 10219 S355J2H ERW: Te Hanganga o ngā Rauemi me ngā Āhuatanga Mahi
Ko te EN 10219 S355J2H he wāhanga hanganga tuwhera kua whakarewahia, he mea hanga ki te matao, he mea hanga mai i ngā maitai kore-koranu me ngā maitai angiangi. Ko te "S" e tohu ana i te maitai hanganga, ko te "355" e tohu ana i te kaha whakaputa iti rawa o te 355 MPa, ko te "J2" e tohu ana i te whakamātautau pānga Charpy i te -20°C (iti rawa 27J), ā, ko te "H" e tohu ana i te wāhanga tuwhera.
Ki te whakatauritea ki ngā momo iti ake pēnei i te S235JRH (235 MPa te hua) me te S275JRH (275 MPa te hua), he nui ake te kaha o te S355J2H, me te pupuri tonu i te kaha whakarewa, te kaha hanga, me te pakari i te pāmahana iti. Nā te whakatauranga pānga J2 i pai ai mō ngā tono āhuarangi makariri e hiahiatia ana te ātete pānga i te -20°C. Ko tēnei momo te wāhanga hanganga tuwhera tino whānuitia mō te hanganga whare, ngā piriti, me ngā hanganga moana puta noa i Ūropi me ngā mākete o te ao.
Te Hanganga Matū o te Paipa Rino EN 10219 S355J2H ERW (Tātaritanga Koro, % mā te papatipu):

Ngā Pātai Auau (FAQ)
P: He aha te rerekētanga i waenga i te S355J2H me ētahi atu momo EN 10219 pēnei i te S235JRH me te S275JRH?
A: Ko te kaha whakaputa iti rawa o S235JRH he 235 MPa, ko te S275JRH he 275 MPa, ā, ko te S355J2H he 355 MPa. Ko te S355J2H te mea tino kaha i roto i ēnei momo e toru. Hei tāpiri, ko te whakatauranga pānga J2 o S355J2H (-20°C, iti rawa 27J), ko te S235JRH me te S275JRH he whakatauranga pānga JR (mahana rūma, iti rawa 27J). Mō ngā tono e hiahia ana ki te kaha teitei ake, ki te ātete pānga pāmahana iti rānei, ko te S355J2H te whiringa pai. Mō ngā kaupapa e hiahia ana ki te kaha teitei ake (420 MPa, 460 MPa rānei), kei te wātea a S420MH me S460MH.
P: He aha te tikanga o te tohu "J2H" i roto i te S355J2H?
A: Ko te wehewehenga o te tohu e whai ake nei: Ko te "S" e tohu ana i te maitai hanganga, ko te "355" e tohu ana i te kaha whakaputa iti rawa o te 355 MPa, ko te "J2" e tohu ana i te whakamātautau pānga Charpy i te -20°C me te iti rawa o te kaha toharite 27J, ā, ko te "H" e tohu ana i te wāhanga kōhao (i hangaia i te makariri). Hei whakatairite: "JR" = pānga pāmahana rūma (20°C), "J0" = pānga 0°C, "J2" = pānga -20°C, "K2" = pānga -20°C me te kaha teitei ake (iti rawa 40J).
Q: Ka taea te whakamahi i te S355J2H mō ngā hanganga whakarewa? He aha ngā tikanga whakarewa e taunakitia ana?
A: Ae, he tino pai te kaha o te S355J2H ki te whakarewa nā te mea he iti te waro (CEV ≤ 0.45%). Ko ngā tukanga whakarewa e taunakitia ana ko te MAG (135), te TIG (141), te MMA (111), me te SAW (12). Kāore e hiahiatia te whakamahana i mua mō ngā matotoru pakitara i raro i te 20mm i raro i ngā āhuatanga noa o te toa. Mō ngā wāhanga matotoru ake, mō ngā pāmahana iti rānei, e taunakitia ana te whakamahana i mua i te 50-100°C. Me ōrite ngā mea whakarewa ki te kaha o te rauemi turanga (te tikanga ER70S-6, te mea rite rānei). Me whakarite tonu i ngā tukanga whakarewa kia rite ki te EN 1090, ki ngā paerewa rānei e tika ana.
