Ihoʻolauna:
Ma ke kahua o ka hana kila, ʻelua mau papa i kū i waho - ʻo S275JR a me S355JR. No nā mea ʻelua i ke kūlana EN10025-2 a hoʻohana nui ʻia i nā ʻoihana like ʻole. ʻOiai ke kani like nei ko lākou mau inoa, he mau waiwai kū hoʻokahi ko kēia mau pae e hoʻokaʻawale iā lākou. Ma kēia blog, e ʻeli mākou i ko lākou mau ʻokoʻa nui a me nā ʻano like, e nānā ana i ko lākou ʻano kemika, nā waiwai mechanical, a me nā ʻano huahana.
Nā ʻokoʻa o ka hoʻohuihui kemika:
ʻO ka mea mua, e kamaʻilio kākou i nā ʻokoʻa o ke ʻano kemika. ʻO S275JR ke kila kalapona, ʻoiai ʻo S355JR ke kila me ka hui haʻahaʻa. Aia kēia ʻokoʻa i ko lākou mau mea kumu. Loaʻa i ke kila kalapona ka hao a me ke kalapona, me nā liʻiliʻi o nā mea ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, ʻo nā kila me ka hui haʻahaʻa, e like me S355JR, loaʻa nā mea hui hou e like me ka manganese, silicon, a me ka phosphorus, e hoʻonui ai i ko lākou mau waiwai.
Ke ʻano hana mīkini:
Ma ke ʻano o nā waiwai mechanical, hōʻike ʻo S275JR a me S355JR i nā ʻokoʻa koʻikoʻi. ʻO ka ikaika haʻahaʻa loa o S275JR he 275MPa, ʻoiai ʻo S355JR he 355MPa. ʻO kēia ʻokoʻa ikaika e kūpono ai ʻo S355JR no nā noi kūkulu e pono ai ka ikaika nui aʻe e kū i nā ukana kaumaha. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻoi aku ka liʻiliʻi o ka ikaika tensile o S355JR ma mua o S275JR.
ʻAno huahana:
Mai ka manaʻo o ke ʻano o ka huahana, ua like ʻo S275JR me S355JR. Hoʻohana ʻia nā papa ʻelua i ka hana ʻana i nā huahana pālahalaha a lōʻihi e like me nā papa kila a me nā paipu kila. Ua hoʻolālā ʻia kēia mau huahana no nā ʻano hana like ʻole ma nā ʻoihana mai ke kūkulu ʻana a i ka mīkini. Eia kekahi, hiki ke hana hou ʻia nā huahana semi-finished i hana ʻia me ke kila kiʻekiʻe non-alloy i ʻōwili wela ʻia i nā huahana like ʻole.
Kūlana EN10025-2:
No ka hāʻawi ʻana i kahi ʻano ākea, e kūkākūkā kākou i ke kūlana EN10025-2 e pili ana i ka S275JR a me S355JR. Hoʻākāka kēia Kūlana ʻEulopa i nā kūlana hoʻouna loea no nā huahana pālahalaha a lōʻihi, me nā papa a me nā paipu. Hoʻokomo pū ia i nā huahana semi-hoʻopau ʻia e hana hou ʻia ana. Hōʻoia kēia kūlana i ka maikaʻi mau ma nā ʻano like ʻole a me nā ʻano o ke kila non-alloy i ʻōwili wela ʻia.
Nā mea like o S275JR a me S355JR:
ʻOiai ko lāua ʻokoʻa, he mau mea like ko ka S275JR a me ka S355JR. Ua kūlike nā papa ʻelua me nā kūlana EN10025-2, e hōʻike ana i ko lāua pili ʻana i nā ana hoʻomalu maikaʻi. Eia kekahi, he nui nā noi a lākou ma nā ʻoihana like ʻole ma muli o ko lākou mau waiwai maikaʻi, me ka hiki ke hoʻopili maikaʻi ʻia a me ka hiki ke hana ʻia. Eia kekahi, he mau koho kaulana nā papa ʻelua no ke kila kūkulu a hiki ke hāʻawi i ko lākou mau pono ponoʻī ma muli o nā koi kikoʻī.
