300 kila kuhiliʻole–ka poʻokela lanakila ʻole no ka pale ʻana i ka ʻino

ʻAʻole i hana ʻia nā kila kila a pau. ʻOiai hāʻawi nā mea a pau i kahi pae o ka pale ʻana i ka corrosion, ʻaʻohe mea i kūpono i ka pale o 300 series metala. Aia kēia me nā kila 400 series kaulana loa; ʻoiai he kūpono ia no kekahi mau noi, hiki ke pilikia i ka Hydrogen Assisted Stress Corrosion Cracking (HASCC) a hiki ke hoʻomohala i ka ʻōpala pōʻino me ka lōʻihi o ka ʻike ʻana i nā mea ʻoi aku ka ikaika. Hoʻopilikia kēia i ka pono o ka hoʻopili ʻana o ka screw ma ka nāwaliwali

• Huki i nā waiwai
• Ka ikaika shear
• Ka ikaika tensile
• ʻO ka ductility

No kēia kumu, ua hoʻomohala ʻo DD Fasteners i kāna hopena hoʻopaʻa bi-metal paʻa ponoʻī me ka hoʻohana ʻana i ka 304 stainless steel, hiki ke kūpaʻa e kū i nā pilina metala like ʻole, pollution, a me nā wahi ʻino loa me ka ʻole o ka hoʻopaʻapaʻa ʻana i ka pono pili.

E pale i nā hemahema e pili ana i ka corrosion ma ke koho ʻana i ka mea paʻa pono i ka manawa mua.

ʻO ka laina Bi-Metal he 304 mau wili kila kila no nā ʻano hoʻohana i manaʻo ʻia, ʻo ia hoʻi

• #10-16 Lae Māhele 2 – hiki i kēia mea hoʻopaʻa ke hoʻopili i nā mea hoʻopili metala māmā, e like me ka pā pale a i ʻole ka hoʻokomo ʻana i ka envelopp. Loaʻa iā ia kahi mea holoi hex haʻahaʻa kūpono no ka ACM a me ka MCM framing.
• #12-14 Lae Māhele 3 – Hāʻawi kēia 304 wili kila kila i kekahi o nā pono like me ka mea hoʻopaʻa i ʻōlelo ʻia ma luna akā me ka ikaika hoʻohui a puni a me ka hiki ke hoʻoheheʻe hohonu.
• #12-14 Lae Thread 3 - me Pan Head – e like me ka mea i luna, pili pū kēia wili me nā pilina bi-metal māmā a me waena. Eia nō naʻe, kūpono ke ʻano o ke poʻo pan i nā papahana i ʻike ʻia nā wili.
• #12-24 Mānoanoa 5 – hiki i kēia wili kila 304 ke hoʻowili iā ia iho i loko o ka metala hapalua ʻīniha ka mānoanoa a hāʻawi i ka ikaika tensile, shear, a me ka torsional ma mua o nā mea paʻa bimetal a mākou i ʻōlelo ai ma mua. Hele mai ia me kahi 5/16″ AF hex washer poo.
