He aha ke ʻano o nā hōʻailona ma nā poʻo Bolt?

ʻO ka papa hana bolt maʻamau i loaʻa i kēia manawa, ʻo ia ka helu metric i hoʻonohonoho ʻia e ISO, aia nā helu ʻelua i hoʻokaʻawale ʻia e kahi kiko a ua kaha ʻia ma luna a i ʻole ʻaoʻao o ke poʻo bolt a i ʻole nati. ʻO nā mea maʻamau he 8.8, 10.9 a me 12.9.

E hoʻonui i ka helu ma mua o ka helu decimal me 100 e hāʻawi i ka ikaika uʻi liʻiliʻi loa o ka bolt. ʻO ka helu ma hope o ka helu decimal i hoʻonui ʻia me ka 10 e hāʻawi i ka pākēneka o ka ikaika e pili ana i ka ikaika tensile liʻiliʻi. ʻO kahi laʻana, ʻo ka ikaika tensile o ka papa 8.8 e pili ana i 800MPa, a ʻo ka ikaika hoʻohua ma kahi o 800 * 80% = 640MPa. Ua ʻike paha ʻoe i nā logo ʻelua ma lalo nei.

ʻO kēia ka hōʻailona no nā bolts kila kila a i ʻole nati, ʻo A2 ke kū nei304 kila kilaa ʻo A4 ke kū nei no 316 kila kila. Hōʻike ka helu ma lalo nei i ka ikaika tensile a e ʻokoʻa ma muli o ka ikaika tensile o ka bolt. No ka laʻana, ʻo 70 ke ʻano o ka ikaika tensile e like me 700MPa kila kila maʻamau. He maikaʻi ke kūpaʻa corrosion nā ʻelua ʻelua, ʻoi aku ka maikaʻi o 316 ma mua o 304, a kūpono i nā wahi me nā koi kiʻekiʻe.

He mau nīnau paha kāu, no ke aha i loaʻa ʻole ai nā māka ma kekahi mau poʻo bolt? ʻO ia ka mea maʻamau, ʻoi aku ka haʻahaʻa o ka pae hana o ka bolt, e like me ka pae 4.8 a i ʻole pae 5.8, ʻaʻole i kaha ʻia.
