SAE8620H Paʻa Poʻa Poʻo /GB 20CrNiMo Paʻa kila
Nā hiʻohiʻona
ʻO 8620 ke kila kila me ka hao, carbon, silicon, molybdenum, manganese, nickel, chromium, sulfur a me phosphorus.Pono kēia mau mea hoʻohui i loko o kekahi mau pākēneka paona e hana i ka alloy 8620.Manaʻo ʻia e hoʻopaʻakikī ʻia ke kila e ka carburization a ukali ʻia e kahi ʻaila, e kūʻē i ka wai, kinai.He haʻahaʻa ka nui o ke kaumaha ma mua o ka haʻihaʻi ʻana ma .28 lb no kēlā me kēia ʻīniha kuea, ʻoiai ʻo kona ikaika tensile - ʻo ka nui o ke kaumaha ma mua o ka haki ʻana - he haʻahaʻa, ma 536,4 Mpa.ʻO ka awelika tensile ikaika o nā mea hao hao he 758 a 1882 Mpa.
Ke hoʻopili pono ʻia ka huila 8620 - hoʻomehana ʻia i kahi mahana i hoʻonohonoho ʻia a laila ʻike ʻia i kahi mea i loaʻa i ke kalapona, kahi hana e hoʻohui i kahi papa kalapona i waho o ke kila, a laila e ikaika ai - hoʻohana ʻia ia e hana i kēlā mīkini. nā ʻāpana e like me nā mea hana, nā crankshaft, a me nā apo.ʻO Carburized 8620 alloy he ikaika a paʻa, ʻo ia ke kumu i makemake ʻia ai no kēia mau ʻāpana.
