GCr15 wela olokaa kila poepoe kaola

ʻO GCr15 he kila maʻamau i hoʻohana ʻia no ka hana ʻana i nā pōpō a me nā apo o ka halihali. Loaʻa i ka huahana nā hiʻohiʻona o ka hui pū ʻana-kemika, haʻahaʻa haʻahaʻa o nā mea ʻino, maʻemaʻe kiʻekiʻe, carbide puʻupuʻu maikaʻi, maikaʻi ka maikaʻi o ka ʻili. Loaʻa iā ia nā hiʻohiʻona o kahi ākea o ka plastic, ka maikaʻi o ka mālama ʻana i ka wela, ka ʻaʻahu, a me ka paʻakikī kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, ka ikaika kiʻekiʻe o ka hoʻopā ʻana i ka luhi. Loaʻa iā ia ka waiwai machining maikaʻi ma hope o ka spheroidize annealing. ʻO GB GCr15 ke kila kila ʻo GB maʻamau Alloy Bearing kila, No ke kalapona kiʻekiʻe kiʻekiʻe kiʻekiʻe, alloy chromium, manganese kila. ʻO nā waiwai GB GCr15 he chromium, manganese alloy steel specification. Ua like ka GCr15 me AISI 52100, DIN 100Cr6. Hiki i ka hapa nui o nā noi ke pani kekahi i kekahi.

Hoʻoponopono wela e pili ana

• Hoʻopili ʻia ʻo GCr15 Alloy me ke kila

Hoʻomaʻamaʻa mālie i ka 790-810 ℃ a hāʻawi i nā manawa kūpono, e hoʻomaʻamaʻa maikaʻi ʻia ke kila, A laila hoʻomaha mālie i ka umu. Loaʻa ka paʻakikī ʻokoʻa i nā ala annealing ʻokoʻa. E loaʻa i ka GCr15 ke kila amo ka paʻakikī MAX 248 HB （Brinell hardness）.

• ʻO ka hoʻopau ʻana a me ka mahana o GCr15 Alloy me ke kila

Hoʻomaʻamaʻa mālie i ka 860 ° C, A laila e kinai ʻia me ka ʻaila e loaʻa iā 62 a 66 HRc paʻakikī. ʻO ka wela wela kiʻekiʻe: 650-700 ℃, ʻoluʻolu i ka ea, loaʻa ka paʻakikī 22 a 30HRC. ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa: 150-170 ℃, ʻoluʻolu i ka ari, loaʻa ka paʻakikī 61-66HRC.

• ʻO ka hana wela a me ka hana anu o GCr15 Alloy me ke kila

Hiki i ke kila GB GCr15 ke hana wela ma 205 a 538°C, GCr15 Hiki ke hoʻohana ʻia ke kila kila me ka hoʻohana ʻana i nā ʻenehana maʻamau i nā kūlana annealed a maʻamau.

Nā noi

Hoʻohana nui ʻia ke kila GB GCr15 no nā ʻano noi like ʻole i hoʻohana ʻia i nā bearings i ka mīkini wili. ʻO nā noi maʻamau e like me nā kino valve, nā paila a me nā mea pono, ka ukana kiʻekiʻe o ka huila, nā bolts, nā poʻo poʻo pālua, nā mīkini, ka ʻenekini puhi ahi. ʻO nā locomotives uila, nā mea hana mīkini, nā trak, nā mea ʻōwili kila, ka mīkini hoʻoluliluli, kaʻa kaʻaahi, a me nā mīkini hoʻoili ʻana i ka pahu kila ma ka pōpō kila, ka wili a me ka lima lima, etc.
