Hana ʻia nā ʻili ʻoihana i nā ʻano like ʻole a me nā standards.Steel alloys i kahi kiʻekiʻe loa e hoʻokuʻu i nā koʻikoʻi kiʻekiʻe loa ma lalo o ka mana o ka mālama ʻana i ka wela, e alakaʻi ana i ke koho ʻana o kēia huila i ka wā e hana ana i nā kī kila i hoʻohana ʻia i nā hale ʻoihana. a i kekahi manawa ʻo ka vanadium (hoʻohui ʻia ka vanadium i nā pūhui kila e pono ai ka elasticity) i loaʻa i nā pūhui kila.
I ka ʻoihana kūkulu, hoʻohana nui ʻia nā bolts a me nā nati i ka hana ʻana i nā hale, nā alahaka, nā dams a me nā mea kanu mana. e nana i lalo.
Hoʻohana ʻia nā ʻūlū i hoʻohana ʻia i ke kūkulu ʻana i nā kuʻi kuʻi i ke kila kila kiʻekiʻe, ma ke ʻano he 10.9 kila. ʻO ka papa 10.9 ke ʻano o ka tensile ikaika tensile o ka wili hana ma kahi o 1040 N / mm2, a hiki ke kū i ka 90% o ka nui o ke koʻikoʻi i hoʻopili ʻia i ke kino wili i ka ʻāpana elastic me ka 4.6 pared iron me ka hao ʻole .5. 8.8 kila maloʻo, ʻoi aku ka ikaika o ka tensile a ʻoi aku ka paʻakikī o ka mālama ʻana i ka wela i ka hana.
ʻOkoʻa mai nā bolts hexagon maʻamau a me nā nati, ua hana ʻia nā bolts hexagon maʻamau a me nā nati e like me ka DIN931 maʻamau e like me ka hapalua, e like me ka DIN933 maʻamau e like me ka piha piha, a he maʻalahi nā wili hexagonal, hana pinepine ʻia e like me ka DIN6914 maʻamau. hana ʻia i ka DIN6915. ʻO nā wili o kēia hana ua kaha ʻia ʻo 10HV a ʻo ka matt black phosphating no ka hoʻomaikaʻi ʻana i ka ʻōpala o ke kaiapuni a i ʻole ka wela wela galvanized a i ʻole ka hohonu chrome matt kala, ʻelua me ka hoʻopau metala.
