ʻO S355 a me Q355 nā inoa ʻelua no ke kila kūkulu, akā hele mai lākou mai nā kūlana like ʻole a he ʻokoʻa kekahi i kā lākou mau kikoʻī a me nā noi.
Ke kila S355
Kūlana: EN 10025-2 (European Standard)
Papa: S355
Wehewehe: He kila kūkulu haʻahaʻa-alloy ikaika kiʻekiʻe ʻo S355 me ka ikaika haʻahaʻa loa o 355 MPa. Hoʻohana pinepine ʻia ia i ke kūkulu ʻana a me nā noi kūkulu ma muli o kona hiki ke hoʻopili maikaʻi ʻia a me ka mīkini.
Nā Subgrades maʻamau:
S355JR: Ke kila kūkulu maʻamau me ka ikaika hua liʻiliʻi o 355 MPa a me ka ikehu hopena o 27J ma ka mahana o ka lumi.
S355J0: Ka ikehu hopena liʻiliʻi loa o 27J ma 0°C.
S355J2: Ka ikehu hopena liʻiliʻi loa o 27J ma -20°C.
