1.2767 Alloy Steel Round Bar

1.2767 / X45NiCrMo4 yog cov pa roj carbon ntau dua ntawm tus qauv 4¼ feem pua ​​​​nickel cua / roj hardening hlau. 1.2767 / X45NiCrMo4 ua tau zoo hardness thiab haum rau cov ntawv thov xav tau ntxiv hnav tsis kam.

1.2767 yog ib hom Nickel txias ua haujlwm cov cuab yeej hlau. Zoo hardenability thiab thougness. Muaj peev xwm rau polishing, photoetching thiab erosion kho. Daim ntawv thov suav nrog cov cuab yeej forging, tuag ntawm txhua yam, cov duab thiab qhov ntau thiab tsawg, kub forging thiab nias cov cuab yeej rau hlau thiab hlau. Pwm, bushings, piercers, thiab lwm yam.

1.2767 yog cov roj carbon ntau dua ntawm tus qauv 4.25 feem pua ​​​​nickel roj hardening hlau. Nws yog cov cuab yeej zoo hlau uas ua tiav cov kev cuam tshuam siab thiab lub zog compressive thiab tsim nyog rau cov ntawv thov xav tau ntxiv hnav tsis kam. Nrog nws cov yam ntxwv ntawm zoo tag nrho hardenability, zoo polishability thiab zoo heev toughness no txias ua hauj lwm cuab tam steel specification yog dav siv rau yas pwm daim ntaub ntawv.

Mechanical Properties
Cov khoom siv tshuab feem ntau suav nrog lub zog tensile, lub zog tawm los, elongation, cheeb tsam lossis txo qis, hardness, cuam tshuam tus nqi, tsis yog xim hlau suav nrog thiab lwm yam. Kev kho cua sov sib txawv, cov khoom siv kho tshuab yuav txawv, xws li annealed. Yog tias koj xav paub cov khoom, thov hu rau tus neeg muag khoom.

Kev Xa Khoom

EAF ntxiv (ESR) los yog EAF ntxiv LF ntxiv rau VD ntxiv (ESR), Kub dov los yog Forged, Annealed, Hardness Tsawg dua los yog sib npaug rau 285HB, Dub nto los yog Machined nto (Peeled, Tig, Grinded), UT 100 feem pua ​​​​Ntau

Annealing

610 txog 650 degree Slow tswj cua txias hauv qhov cub ntawm tus nqi ntawm 10 txog 20 degree / hr nqes mus rau kwv yees. 600 degree, ntxiv txias hauv huab cua. Hardness tom qab annealing: max. 285 HB. Stress relieving Approx. 650 degree qeeb txias hauv qhov cub; npaj los txo kev ntxhov siab los ntawm kev siv tshuab dav dav, lossis cov duab tsis yooj yim. Tom qab cua sov, tuav hauv nruab nrab cua rau 1 mus rau 2 teev. Hardening 840 txog 870 degree Roj, ntsev da dej (300 txog 400 degree), huab cua. Tuav lub sij hawm tom qab kub sib npaug: 15 mus rau 30 feeb. Tau txais hardness: 53 - 57 HRC hauv huab cua. 54 - 58 HRC hauv roj lossis ntsev da dej. Tempering Slow cua sov rau tempering kub tam sim ntawd tom qab hardening / sij hawm nyob rau hauv lub cub tawg 1 teev rau txhua 20 hli ntawm workpiece thickness, tab sis tsawg kawg yog 2 teev / cua txias. Rau qhov nruab nrab hardness cov nuj nqis yuav tsum tau, thov mus rau daim ntawv tempering. Rau qee qhov xwm txheej peb pom zoo kom txo qhov kub thiab txias thiab ua kom lub sijhawm tuav.
