Ihoʻolauna:
Ma ke kahua o ka hana kila, ʻelua mau māka e kū nei - S275JR a me S355JR. Aia nā mea ʻelua i ka maʻamau EN10025-2 a hoʻohana nui ʻia i nā ʻoihana like ʻole. ʻOiai ke kani like ko lākou mau inoa, loaʻa i kēia mau pae nā waiwai kūʻokoʻa e hoʻokaʻawale iā lākou. Ma kēia moʻomanaʻo, e ʻimi mākou i kā lākou ʻokoʻa nui a me nā mea like, e nānā ana i kā lākou haku mele, ʻano mechanical, a me nā ʻano huahana.
Nā ʻokoʻa o ka haku mele ʻana:
ʻO ka mua, e hoʻoponopono kākou i nā ʻokoʻa o ka haku melemele. ʻO S275JR ke kila kalapona, aʻo S355JR ke kila kila haʻahaʻa. Aia kēia ʻokoʻa i kā lākou mau mea kumu. Loaʻa ka hao a me ke kalapona, me ka liʻiliʻi o nā mea ʻē aʻe. Ma ka ʻaoʻao ʻē aʻe, ʻo nā kila haʻahaʻa haʻahaʻa, e like me S355JR, loaʻa nā mea hoʻohui hou e like me ka manganese, silicon, a me ka phosphorus, e hoʻonui ai i kā lākou waiwai.
Hana mīkini:
Ma keʻano o nā waiwai mechanical, hōʻike nā S275JR a me S355JR i nāʻokoʻa nui. ʻO ka ikaika haʻahaʻa haʻahaʻa o S275JR ʻo 275MPa, ʻoiai ʻo S355JR ʻo 355MPa. ʻO kēia ʻokoʻa ikaika e hoʻolilo iā S355JR i mea kūpono no nā noi hoʻolālā e koi ana i ka ikaika nui aʻe e kū i nā ukana kaumaha. Eia naʻe, pono e hoʻomaopopo ʻia ʻoi aku ka liʻiliʻi o ka ikaika tensile o S355JR ma mua o S275JR.
ʻano huahana:
Mai ka hiʻohiʻona o ke ʻano huahana, like ka S275JR me S355JR. Hoʻohana ʻia nā māka ʻelua i ka hana ʻana i nā huahana pālahalaha a lōʻihi e like me nā pā kila a me nā paipu kila. Hoʻolālā ʻia kēia mau huahana no nā ʻano hana like ʻole i nā ʻoihana mai ke kūkulu ʻana i ka mīkini. Eia kekahi, hiki ke hana hou ʻia nā huahana semi-finished i hana ʻia me ke kila kila kiʻekiʻe i hoʻopaʻa ʻia i loko o nā huahana like ʻole.
EN10025-2 maʻamau:
No ka hāʻawi ʻana i kahi pōʻaiapili ākea, e kūkākūkā kākou i ka maʻamau EN10025-2 e pili ana i ka S275JR a me S355JR. Hōʻike kēia European Standard i nā kūlana hāʻawi ʻenehana no nā huahana pālahalaha a lōʻihi, me nā papa a me nā paipu. Loaʻa pū kekahi i nā huahana semi-finished e hana hou ana. Mālama kēia maʻamau i ka maikaʻi kūlike ma waena o nā māka like ʻole a me nā hiʻohiʻona o ke kila non-alloy wela.
He aha ka S275JR a me S355JR i like:
ʻOiai ko lākou ʻokoʻa, loaʻa i ka S275JR a me S355JR kekahi mau mea like. Hoʻopili nā papa ʻelua i nā kūlana EN10025-2, e hōʻike ana i ko lākou pili ʻana i nā ana mana koʻikoʻi. Eia kekahi, loaʻa iā lākou ka nui o nā noi i nā ʻoihana like ʻole ma muli o ko lākou mau waiwai maikaʻi, me ka weldability maikaʻi a me ka processability. Eia kekahi, ʻo nā papa ʻelua he mau koho kaulana no ke kila kila a hiki ke hāʻawi i kā lākou pono ponoʻī ma muli o nā koi kikoʻī.
