S235JR pā kila

S235JR Mea Hoʻolauna
ʻO EN 10025 S235JR mea (1.0038 kila) he ʻano ʻEulopa maʻamau i hoʻopaʻa ʻia me ke kila kila ʻole. Loaʻa iā ia ka plasticity maikaʻi, ka paʻakikī a me ka weldability, kekahi ikaika a me nā ʻano kulou anu anuanu. No ka kikoʻī, ka ʻikepili a me nā mea like, e ʻoluʻolu e ʻike i nā papa ma lalo.
Mea S235JR manaʻo (koho):
ʻO ka "S" he pōkole no ke kila hana;
ʻO ka "235" e pili ana i ka ikaika hoʻohua haʻahaʻa (MPa) no ka mānoanoa kila ≤ 16mm;
Hōʻike ʻo "JR" i ka papa maikaʻi e pili ana i ka waiwai ikehu charpy impact test ≥ 27 J, ma ke ana wela 20 ℃;
"C" 'o ia ho'i, kūpono ka mea no ka lele anu, ka piko anu, ka hana anu a i'ole ke kaha ki'i anu, e la'a. S235JRC (1.0122).
ʻO 1.0038 ka helu kila o kēia kila.
ʻO ke kila kalapona S235JR nā kūlana hoʻopuka maʻamau penei:
+AR 'o ia ho'i "as-rolled" a me ka ho'opuka 'ana me ka 'ole o ka'ōwili kūikawā a me ka /a i 'ole ka ho'oponopono wela.
ʻO + N ke kū nei no ka "normalized or normalized formed"
+ M pili i ka "thermomechanically i hana ʻia - TMCP"
ʻO +C ka "hana anu i paʻakikī"
+ ʻO ke ʻano o ka mateiral aia i ke kūlana annealed palupalu.
+ AT 'o ia ho'i, aia ke kila i loko o ke kūlana annealed solution.
Laʻana 1: Ke ʻōwili ʻia a maʻamau paha ke kūlana hoʻopuka, hāʻawi ʻia ka inoa kila ma S235JR+AR (1.0038+AR) a i S235JR+N (1.0038+N).
Ka Laʻana 2: S235JRC kila 'o ia hoʻi, kūpono ka mea no ka hoʻoheheʻe ʻana i ke anu, ka piko anu, ka hana anu a i ʻole ke kiʻi anu.
Laʻana 3: Inā hāʻawi ʻia ke kila S235JRC ma ke ʻano o ka hana anuanu, ua kapa ʻia ʻo S235JRC+C (1.0122+C).
