ʻO S235JR he kila kila non-alloy maʻamau o ʻEulopa, e like me ka standard national Q235B, ʻo ia ke kila kila kila me ka haʻahaʻa kalapona.Hoʻohana ʻia ia no ka welding, bolting a me nā hale riveting.
ʻO ke kila hoʻolālā kalapona he ʻano kila kalapona.ʻO ka maʻi kalapona ma kahi o 0.05% ~ 0.70%, a hiki i kekahi ke kiʻekiʻe e like me 0.90%.Hiki ke hoʻokaʻawale ʻia i ke kila kila kila maʻamau a me ke kila kila kila kiʻekiʻe.Hoʻohana nui ʻia ia i ke kaʻaahi, ke alahaka, nā hana hana like ʻole, ka hana ʻana i nā ʻāpana metala like ʻole e halihali ana i ka ukana static, nā ʻāpana mechanical ʻole a me nā welded maʻamau ʻaʻole pono ka mālama wela.
Hōʻike ka papa kila S235JR
“S”: Ke kila kila maʻamau maʻamau maʻamau ʻEulopa;
“235″: ʻo 235 ka ikaika o ka hua, ʻāpana: MPa;
"JR": hopena i ka wela maʻamau
3. S235JR papa kila hoʻokō kūlana: EN10025 maʻamau
4. Ke kūlana hoʻouna o S235JR ke kila kila: ka'ōwili wela, ka'ōwili hoʻomalu, ka maʻamau, a me nā mea'ē aʻe.
5. S235JR pā kila mānoanoa kuhikuhi hana pono: Z15, Z25, Z35.
ʻO ka hoʻopili ʻana i nā mea hoʻohui kemika o ka pā kila S235JR
S235JR haku mele:
S235JR pā kila kila maʻiʻo C: ≤ 0.17
S235JR pā kila kila maʻiʻo Si: ≤ 0.35
S235JR pā kila manganese maʻiʻo Mn: ≤ 0.65
Phosphorus maʻiʻo o S235JR pā kila P: ≤ 0.030
S235JR pā kila sulfur maʻiʻo S: ≤ 0.030
3、 Mechanical waiwai o S235JR pā kila
Mānoanoa 8-420mm:
Hiki i ka ikaika MPa: ≥ 225
ʻO ka ikaika tensile MPa: 360 ~ 510
Ka lōʻihi%: ≥ 18
4、 S235JR kaʻina hana pā kila:
Ke kahe kaʻina hana: ka hoʻoheheʻe ʻana o ka umu uila → LF/VD furnace essence → hoʻolei ʻana → hoʻomaʻemaʻe ingot → hoʻomaʻemaʻe ingot → ʻōwili pā → hoʻopau ʻana → ʻoki ʻana i ka laʻana → nānā hana → hale kūʻai.
5、 S235JR ka nui o ka hoʻokomo ʻana i ka mānoanoa
8-50mm * 1600-2200mm * 6000-10000mm
50-100mm * 1600-2200mm * 6000-12000mm
100-200mm * 2000-3000mm * 10000-14000mm
200-350mm*2200-4020mm*10000-18800mm
Hoʻokaʻawale ʻili
ʻili maʻamau (FA)
Ua 'ae 'ia ka 'ili o ka pickled e loa'a nā hemahema li'ili'i a kūloko e like me nā lua, dents, scratches, etc. nona ka hohonu (a ki'eki'e) 'a'ole i oi aku ma mua o ka hapalua o ka mānoanoa tolerance o ke kila, akā, ka palena iki allowable mānoanoa o ke kila a me e hōʻoiaʻiʻo ʻia ke kaula kila.
Kiʻekiʻe kiʻekiʻe (FB)
Ua ʻae ʻia ka ʻili o ka pickling e loaʻa nā hemahema kūloko i pili ʻole i ka formability, e like me nā ʻōpala liʻiliʻi, nā ʻīwī liʻiliʻi, nā lua liʻiliʻi, nā māka ʻili liʻiliʻi a me nā ʻokoʻa kala.
Hoʻohana waiwai
Hoʻohana nui ʻia no ke kūkulu ʻana, ke alahaka, ka moku, nā ʻāpana kaʻa kaʻa, ka hana ʻana i nā mea hana like ʻole, nā mea ʻokiʻoki, nā mold a me nā mea ana.
