HRC wela owili kila wili DIN ST37
haku mele ʻana
ʻO ka hui kemika kikoʻī o ka wili kila wela ST37 e loaʻa ana i ke kalapona (C) 0.17-0.20%, manganese (Mn)
ʻAno
Nui nā ʻano o ka pepa kila i ʻōwili ʻia i loko o nā wili ST37, e komo pū ana i nā ʻōwili wela, nā ʻōwili pickled wela a me nā ʻōwili anu.
ʻOkoʻa kēia mau ʻano i ka mālama ʻana a me ka hoʻohana ʻana. Hoʻopiʻiʻia nā'ōwili'ōwili wela a me nā'ōwili'ōwili wela e loaʻa i kahiʻoi aku ka maʻalahi a kūpono i nā noi e makemake ana i kahi maʻemaʻe; ʻoiai he kiʻekiʻe ka pololei a me ka ikaika o nā coils ʻōwili anuanu a kūpono i nā manawa e koi ai i nā koi ikaika kiʻekiʻe.
Nā waiwai mīkini
Ma ke ʻano o nā waiwai mechanical, hana maikaʻi ʻo ST37 coil metala wela wela.
ʻOkoʻa kona ikaika tensile i nā mānoanoa like ʻole. Ke emi ka mānoanoa ma mua o 3mm, ʻo ka ikaika tensile he 360-510MPa; ke ʻoi aku ka mānoanoa ma mua o 3mm, ʻo ka ikaika tensile ʻo 340-470MPa.
ʻO ka ikaika ≥ 235MPa, elongation ma hope o ka haʻihaʻi ≥ 17%, ka ikehu hopena ≥ 27J (ka wela hopena + 20 ℃).
Hōʻike kēia mau hōʻailona hana i ka DIN ST37 wili kila wela wela ka ikaika a me ka plasticity.

| Ka lōʻihi | 2M a hiki i 12M |
Palapala noi
He ākea loa ke kahua noi o carbon steel coil ST37.
I ka ʻoihana kūkulu, hoʻohana pinepine ʻia e hana i nā ʻāpana kūkulu hale, e like me nā kaola a me nā kolamu, e hōʻoia i ka paʻa o ka hale.
I ka ʻoihana hana mīkini, hiki ke hoʻohana ʻia ka coil carbon steel DIN ST37 no ka hana ʻana i nā ʻāpana mechanical like ʻole, e like me nā mīkini a me nā shafts, e hoʻokō i kāna mau ʻano mīkini maikaʻi.
I ka ʻoihana kaʻa, hoʻohana ʻia ka pepa kila wela i loko o ka coil DIN ST37 e hana i nā chassis kaʻa, kino a me nā ʻāpana ʻē aʻe, e hōʻike ana i ka hana kuʻi maikaʻi a me ka ikaika.
Eia kekahi, loaʻa iā HRC ST37 kekahi kūpaʻa corrosion a kūpono ia no nā ʻano kūlana kaiapuni.
Hoʻouna
E pili ana iā mākou
Aia ʻo Tianjin Lishengda Steel Group ma ke kūlanakauhale ʻo Tangshan, ke kapikala kila o Kina ʻĀkau. Ke hana nui nei kā mākou hui i ke kālepa hoʻokuʻu aku i nā huahana kila, he mau makahiki he nui o ka ʻike ʻana i nā huahana kila, ka nui o ka hoʻokuʻu ʻana i kēlā me kēia makahiki ma kahi o 300,000 tons.
