S355 Rino
Paerewa: EN 10025-2 (Paerewa Pakeha)
Tau: S355
Whakaahuatanga: He maitai hanganga kaha-teitei, he iti-te-koranu te S355, ko te kaha whakaputa iti rawa o te 355 MPa. He mea whakamahi noa i roto i ngā mahi hanga me ngā tono hanganga nā te mea he pai tōna ngāwari ki te whakarewa me te miihini.
Ngā Papa Whakatakoto Noa:
S355JR: He maitai hanganga whānui me te kaha whakaputa iti rawa o te 355 MPa me te kaha pānga o te 27J i te pāmahana rūma.
S355J0: Pūngao pānga iti rawa o te 27J i te 0°C.
S355J2: Te pūngao pānga iti rawa o te 27J i te -20°C.
Q355 Rino
Paerewa: GB/T 1591 (Paerewa Hainamana)
