42CrMo alloy seamless steel yeeb nkab yog ib hom steel yeeb nkab nrog lub zog siab, siab hardness, thiab siab hnav tsis kam, ua los ntawm42CrMo hlau alloy.Nws muaj cov khoom siv zoo, xws li lub zog siab, siab toughness, siab hnav tsis kam, thiab siab corrosion kuj, thiab tsim nyog rau kev tsim cov khoom siv kho tshuab thiab cov cuab yeej siv nrog cov khoom siv siab, siab zog, thiab kev ua haujlwm siab.42CrMo alloy seamless steel kav yog dav siv nyob rau hauv teb xws li aviation, aerospace, automotive, shipbuilding, roj av, tshuaj, metallurgy, kev tsim kho, thiab mechanical manufacturing.
1. Kev kho cua sov specifications rau42CrMo seamless steel rajyog raws li nram no: cua kub kub 1150 ~ 1200 ° C, pib kub 1130 ~ 1180 ° C, thiab xaus kub> 850 ° C, φ> Ntawm 50 hli, qeeb txias.
2. Normalizing specification: Normalizing kub yog 850 ~ 900 ° C, nrog cua txias tom qab tso tawm.
3. Kub kub tempering specification: Tempering kub 680-700 ° C, cua txias tom qab cub tawg.
4. quenching thiab tempering specifications: preheating kub 680-700 ° C, quenching kub 840-880 ° C, roj txias, tempering kub 580 ° C, dej los yog roj txias, hardness ≤ 217HBW.
5. Specification rau sub kub quenching thiab toughening kev kho mob: quenching kub 900 ° C, tempering kub 560 ° C, hardness (37 ± 1) HRC6, induction quenching thiab tempering specification: quenching kub 900 ° C, tempering kub 150-180 ° C , hardness 54-60HRC.
6. 42CrMo steel yog raug rau kev kho mob cryogenic, uas tuaj yeem ua kom tawg tau tawg heev ultrafine carbides los ntawm quenched martensite.Tom qab qhov kub thiab txias ntawm 200 ℃, cov ultrafine carbides tuaj yeem hloov mus rau hauv carbides.
