Hoʻoponopono wela e pili ana
- Hoʻopili ʻia ʻo 20CrNiMo Alloy kila
Hoʻomaʻamaʻa mālie i ka 850 ℃ a hāʻawi i nā manawa kūpono, e hoʻomaʻamaʻa maikaʻi ʻia ke kila, A laila hoʻomaha mālie i ka umu. E loaʻa i ke kila kila 20CrNiMo ka MAX 250 HB (Brinell hardness).
- Paakiki o 20CrNiMo Alloy structural steel
Hoʻomaʻamaʻa mālie i ka 880-920 ° C, A laila ma hope o ka hoʻonā pono ʻana i kēia mahana e kinai i ka ʻaila. ʻO ka huhū ke hiki i nā mea hana ke hiki i ka mahana wela.

Nā noi
Hoʻohana nui ʻia ke kila GB 20CrNiMo no nā ʻano noi like ʻole i hoʻohana ʻia i nā ʻoihana automotive a me nā ʻenehana no nā mea paʻahana a me nā mea like ʻole. ʻO nā noi maʻamau e like me nā kino valve, nā pamu a me nā mea pono, Shaft, ka ukana kiʻekiʻe o ka huila, bolts, bolts poʻo ʻelua, gears, etc.
Nui mau a me ka hoʻomanawanui
Paʻa pōʻai kila: Anawaena Ø 5mm – 3000mm
Pā kila: Mānoanoa 5mm – 3000mm x Laulā 100mm – 3500mm
Paʻa Hexagonal hao: Hex 5mm - 105mm
ʻAʻole i kuhikuhi ʻia ka nui o nā mea ʻē aʻe 20CrNiMo, no laila e ʻoluʻolu e kelepona i kā mākou hui kūʻai ʻike.
Kaʻina hana
Hiki ke ʻoki ʻia nā ʻāpana ʻāpana ʻāpana GB 20CrNiMo i kou nui i makemake ʻia. Eia kekahi, hiki ke hoʻolako ʻia ka 20CrNiMo alloy steel ground bar, e hāʻawi ana i kahi kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kiʻekiʻe kila kila kila kila i kou pono tolerances. Eia kekahi, loaʻa nō hoʻi ke kila GB 20CrNiMo e like me Ground Flat Stock / Gauge Plate, ma nā ʻano maʻamau a me ka nui ʻole.
