Pehea e hoʻokaʻawale ai i nā ʻokoʻa o ka mea a me ka maikaʻi o nā bolts track

PAE MEA:

Nā ʻūmiʻi kūlana kiʻekiʻe: Hana ʻia me ke kila kila ikaika kiʻekiʻe (e like me 40Cr, 42CrMo, kila kila),
me ka ikaika tensile o ≥ 800MPa a me ka paʻakikī o HRC 22-32, hiki ke kū i ka hopena kaumaha.

Nā ʻōwili maikaʻi ʻole: hoʻohana i ke kila kalapona maʻamau (e like me Q235), me ka ikaika tensile haʻahaʻa (e pili ana i 400MPa), hiki ke hoʻololi a haki paha.

Kaʻina hana mālama wela：

Pono nā ʻōwili kiʻekiʻe e hana i ka quenching a me ka tempering treatment (quenching + tempering kiʻekiʻe-mahana),
me ka ʻili like a me ka paʻakikī o ke kumu a ʻaʻohe papa decarburization.

ʻAʻole paha e mālama ʻia ka wela ma nā huahana maikaʻi ʻole a i ʻole he mau kaʻina hana ma lalo o ke kūlana maʻamau, e hopena ana i ka paʻakikī like ʻole (ʻili paʻakikī, ʻiʻo palupalu) a me ka maʻalahi o ka haki ʻana.
