42CrMo paipu kila maʻemaʻe he ʻano paipu kila me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa ʻaʻahu kiʻekiʻe, i hana ʻia42CrMo kila kila.Loaʻa iā ia nā waiwai mechanical maikaʻi, e like me ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, a me ke kūpaʻa corrosion kiʻekiʻe, a kūpono no ka hana ʻana i nā ʻāpana mechanical a me nā mea hana me ka ukana kiʻekiʻe, ikaika kiʻekiʻe, a me nā koi hana kiʻekiʻe.42CrMo paipu kila seamless paipu hoʻohana nui ʻia i nā kula e like me ka mokulele, aerospace, automotive, shipbuilding, petroleum, chemical, metallurgy, construction, and mechanical manufacturing.
1. ʻO nā kikoʻī lapaʻau wela no42CrMo paipu kila maʻemaʻepenei: ka wela wela 1150 ~ 1200 ° C, e hoʻomaka ana ka mahana 1130 ~ 1180 ° C, a me ka wela wela> 850 ° C, φ> Ma 50mm, hoʻomaha mālie.
2. Normalizing kiko'ī: Normalizing ana wela ka 850 ~ 900 ° C, me ka ea hooluolu ma hope o ka hoʻokuʻu.
3. Kiʻekiʻe wela tempering kiko'ī: Tempering wela 680-700 ° C, ea hooluolu ma hope o ka umu ahi.
4. Hoʻopili a me ka hoʻonāʻana i nā kiko'ī: ka mahana wela 680-700 ° C, ka mahana wela 840-880 ° C, kaʻailaʻaila, ka mahana wela 580 ° C, ka wai aiʻole kaʻaila, ka paʻakikī ≤ 217HBW.
5. Hoʻohālikelike no ka hoʻopau ʻana i ka mahana a me ka hoʻomaʻamaʻa paʻakikī: quenching temperature 900 ° C, tempering temperature 560 ° C, hardness (37 ± 1) HRC6, induction quenching and tempering specification: quenching temperature 900 ° C, tempering temperature 150-180 ° C , paakiki 54-60HRC.
6. 42CrMo kila i ka cryogenic lapaʻau, i hiki precipitate loa hoopuehu ultrafine carbide mai quenched martensite.Ma hope o ka haʻahaʻa haʻahaʻa haʻahaʻa ma 200 ℃, hiki ke hoʻololi ʻia kēia mau carbide ultrafine i carbide.
