Ko nga mea katoa e mahia ana e matou ko te nuinga o te hono ki ta matou kaupapa " Kaihoko tuatahi, Whakawhirinaki ki te tuatahi, ko te whakapau i te taha o te kete kai me te haumaru o te taiao mo te Paipa Tio Kounga Kounga Korekore me te Paiherea, Ka waiho e matou te pono me te hauora hei kawenga tuatahi. Inaianei kei a matou he tohunga ngaio. Ko nga roopu hokohoko o te ao i puta mai i Amerika Ko matou to hoa hinonga e whai ake nei Ma te u ki te kaupapa o "Te Whakanuia me te Rapu Pono, Te Tika me te Kotahitanga", ko te hangarau te kaupapa, kei te haere tonu to taatau kamupene ki te whakarato ki a koe. me nga hua tino utu nui me te ratonga whai muri i te hokonga ka tino whakapono matou: he tino rangatira matou.
I roto i nga rauemi putorino maitai hanga noa, ko DIN1629 ST52 tetahi o nga rawa e tino whakamahia ana. I roto i nga paerewa Hainamana, he rite tonu ki te GB / T8162 Q345B. Ko nga mea e rua ka taea te whakakapi tetahi ki tetahi, engari kaore i te tino rite. .
Mo te hanganga matū:
DIN 1629 ST52: C: 0.17%max; P: 0.04%max; S:: 0.04%max; N: 0.009% te teitei
GB / T 8162 Q345B: C: 0.2%max; P: 0.035%max; S:: 0.035%max; N: 0.012%max
Ka kitea ko nga paerewa e rua e kii tahi ana he rite tonu te kiko o nga huānga matū.
Mahinga miihini:
DIN 1629 ST52: Te kaha kaha: 500~650Mpa; Te kaha tuku: 335~355Mpa; Whakaroa (roa): 21%min
GB / T 8162 Q345B: Te kaha kaha: 470 ~ 630Mpa; Te kaha tuku: 295 ~ 345Mpa; Whakaroa (roa): 20% min
He rite ano nga whakaritenga mo nga ahuatanga miihini o nga mea e rua
Tūemi whakamātautau:
Ko te DIN 1629 e hiahia ana ki te whakamatau i te tensile, te whakamatautau whakamaarama, te whakamatautau piri, te tirotiro mata, te tirotiro i te rahi; oti te tātari hua
Ko te GB/T8162 Q345B e hiahia ana ki te tirotiro i te hanganga matū, te whakamatautau tensile, te whakamatautau pakeke, te 20 ℃ te whakamatautau paanga, te whakamatautau whakamaarama, te whakamatautau piko, te whakamatautau hiko kore-whakangaro.
Ka taea te kite ko nga whakaritenga kaupapa whakamatautau o GB/T8162 Q345B e hipoki ana i te DIN1629.
