mea 40cr

ʻO 40Cr ka helu kila maʻamau GB ma Kina, a ʻo 40Cr ke kila kekahi o nā kila i hoʻohana nui ʻia i ka ʻoihana mechanical manufacturing. He maikaʻi nā waiwai mechanical piha, maikaʻi haʻahaʻa haʻahaʻa hopena hopena toughness a me ka haʻahaʻa notch sensitivity.Good kila hardenability, i ka wai kinai paʻakikī i Ф 28 ~ 60 mm, i ka aila quenching hardening i Ф 15 ~ ʻO ke kila kiʻekiʻe ke kūpono. quenching.I ka 174 ~ 229HB ka paʻakikī, ʻo ka machinability pili he 60%. He kūpono ke kila no ka hana ʻana i nā mold plastic sized.

Medium carbon tempered steel, anuanu poʻo make steel.The steel is of moderate price, easy to process and can get some toughness, plasticity and abrasion resistance after proper heat treatment.Normalizing can improve the cutting performance of the blank by promoting the microstructure refinement and approaching the equilibrium state. Tempered at 550 ~ 570 ℃, the steel is the best hardenability. kiʻekiʻe alapine quenching, flame quenching a me ka ili paakiki lapaau.

ʻO nā ʻāpana shaft kekahi o nā ʻāpana maʻamau i ʻike pinepine ʻia i nā mīkini. ʻauamo a me ka ʻauamo.

ʻO 40Cr kahi mea maʻamau o nā ʻāpana shaft. He mea maʻalahi a hiki ke loaʻa i ka hana ʻoki ʻoi aku ka maikaʻi ma hope o ke kinai ʻana a me ka hoʻomaʻamaʻa ʻana (a i ʻole ka hoʻomaʻamaʻa ʻana), a hiki ke loaʻa i nā waiwai mechanical piha kiʻekiʻe e like me ka ikaika a me ka paʻakikī. Ma hope o ke kinai ʻana, hiki i ka paʻakikī o ka ʻili ke hiki i 45 ~ 52HRC.

Hoʻohana nui ʻia ʻo 40Cr i ka hana mechanical. ʻO kēia ʻano kila he mau mea mechanical maikaʻi. ʻO kēia ke kila kalapona kalapona maikaʻi me ka hana hoʻopiʻi maikaʻi, hiki i ka 40Cr ke paʻakikī i ka HRC45 ~ 52. No laila, inā pono e hoʻomaikaʻi ʻia ka paʻakikī o ka ʻili a manaʻo ʻia e hoʻokō ʻia nā ʻano mechanical kiʻekiʻe o 40Cr. e loaʻa ka paʻakikī o ka ʻili kiʻekiʻe a mālama i ka paʻakikī maikaʻi o ka puʻuwai.
