Dab tsi yog cov tshuaj muaj pes tsawg leeg, txhua yam khoom thiab hardness ntawm steel springboard
Steel springboard yog ib yam tseem ceeb ntawm steel springboard thiab ib hom kev ua tau zoo. Steel springboard nyob rau hauv qhov tseeb ntau lawm thiab daim ntawv thov yog tas li los txhim kho qhov tseem ceeb muaj nuj nqi ntawm steel springboard yog ib tug zoo kev kawm ntawm steel springboard, nws cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom yog zoo, hardness kuj kuj loj. Lub hardness ntawm cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom ntawm steel springboard yog dab tsi? Hauv qab no yog cov ncauj lus kom ntxaws sib tham ntawm steel springboard cog los ntawm sawb:
Mechanical zog:
Tensile lub zog Rb (MPa): Ntau dua los yog sib npaug rau 980 Tawm lub zog Rs (MPa): Ntau dua lossis sib npaug rau 785 elongation δ10 (%): 14 ~ 21.5 seem shrinkage (%): tsis tsawg dua 10
Hardness:
Kub dov hardness: 240 ~ 270HB txias dov softness: 190 ~ 220HB txias dov hardness: 300 ~ 340HB tshav kub kho hardness: 38 ~ 60HRC
Kev kho cua sov thiab kev qhia tshwj xeeb quenching 830 degree ± 20 degree, roj txias; Kub 540 degree ± 50 degree (rau kev xav tau tshwj xeeb, ± 30 degree). Qhov ntsuas kub tseem ceeb (kwv yees)Ac1=726 degree , Ac3=765 degree , Ar3=741 degree , Ar1=689 degree , Ms=270 degree . Normalizing specification: Kub 810 ± 10 degree, cua txias. quenching thiab tempering specification: quenching kub 830 ± 10 degree, roj txias; Tempering kub 540 degree ± 10 degree, dej, roj txias. Kev xa khoom kub kub dov steel yog xa hauv cov cua sov kho lossis tsis, txias rub hlau yog xa hauv cov cua sov kho. (2.0-16) * 1250 * C Laisteel / Kub coil / phaj kub 50Mn (2.0-16) * 1250 * C Laisteel / Kub coil / phaj kub 65Mn (2.{25}} ) * 1010/1250 * C Laisteel / Kub coil / kub phaj
