20CrMnTi(H) wela olokaa kila poepoe kaola

ʻO nā hiʻohiʻona o ke kila paʻakikī paʻa paʻa, ke kaʻina hana mālama wela carburizing maikaʻi a me ka hana ʻana o ke kila ma ≤960 ℃ hale palaoa maikaʻi, hoʻohana mau ʻia i ka mahana wela carburizing wela, ʻaʻole ulu ka palaoa i ke koena liʻiliʻi austenite ma hope o ke kinai ʻana, no laila, ʻO ke kila ka ikaika kiʻekiʻe a me ke kū'ē kū'ē, ka hanaʻoki maikaʻi, ka hana nui a me ka 20CrMnTi a me ka 20CrNi kila like. Ka ikaika tensile σ ≥1080MPa, ikaika hua σ ≥885MPa, elongation δ ≥10%, 45% ka ho'ēmiʻana o ka pehu, ka paʻakikī o ka hopena (impact toughness) α ≥69J / cm, ka paʻakikī ≤207 HB, blank size.

GB 20CrMnTi GB/T 3077 Mechanical

ʻO nā mea hana mechanical o GB 20CrMnTi GB/T 3077 metala e hoʻoholo i ka laulā o ka pono o kahi mea a hoʻokumu i ke ola lawelawe i hiki ke manaʻo ʻia. Hoʻohana pū ʻia nā waiwai mīkini e kōkua i ka hoʻokaʻawale a ʻike ʻana i nā mea.

Hōʻike nui ʻia nā ʻāpana hana kino o GB 20CrMnTi GB/T 3077 e ka density, ratio poisson, thermal conductivity, specific thermal capacity, coefficient of thermal expansion, modulus of elasticity, electric resistance value, etc.

Hoʻoponopono wela e pili ana

• Hoʻopili ʻia ʻo 20CrMnTi Alloy Gearing 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 ke kila 20CrMnTi Gearing ka Hardness MAX 248 HB (Brinell hardness).

• ʻO ke kinai a me ka mahana o 20CrMnTi mea kila

Hoʻomaʻamaʻa mālie i ka 788 ° C, A laila hoʻokomo i loko o ka umu ʻauʻau paʻakai e mālama i ka 1191 ℃ a 1204 ℃ .quenching e ka aila loaʻa 60 a 66 HRc paʻakikī. ʻO ka wela wela kiʻekiʻe: 650-700 ℃, ʻoluʻolu i ka ea, loaʻa ka paʻakikī 22 a 30HRC. ʻO ka wela haʻahaʻa haʻahaʻa: 150-200 ℃, ʻoluʻolu i ka ari, loaʻa ka paʻakikī 61-66HRC.

• Hana wela a me ka hana anu o 20CrMnTi Alloy Gearing kila

Hiki i ke kila GB 20CrMnTi ke hana wela ma 205 a i 538°C, 20CrMnTi Bearing/E hiki ke hana anu ke kila kila me ka hoohana ana i na hana ma'amau i ka annealed a ma'amau.
