30CRMOV9 / 1.7707 HAAWINA HUI

ʻO 30CrMoV9 he kila i manaʻo ʻia no ka hana ʻana i nā ʻāpana kinai ʻia a me nā ʻāpana i hoʻoheheʻe ʻia, i hana ʻia i ka mīkini a ma hope o ka nitrided. Hana ʻia ka alloy 30CrMoV9 e EAF /VD /LF a ukali ʻia e ka electroslag refining (ESR) inā pono no ke kumu kūikawā. ʻO nā pahu a, inā pili, hoʻopaʻa ʻia nā forgings i ka hoʻokolokolo ultrasonic ma muli o ka pae like ʻole e like me nā koi o nā mea kūʻai aku. Hāʻawi pinepine ʻia nā lāʻau ʻālohilohi ma ke kūlana annealed, a i ʻole ka annealing mālamalama.
