30CrMnSiA belongs rau alloy qauv steel phaj, kuj belongs rau cov tub rog hlau, 30CrMnSiA tsis tsuas yog muaj zog heev tab sis kuj muaj ib tug tej yam toughness, hnav tsis kam, qaug zog tsis kam, corrosion kuj, cuam tshuam tsis kam thiab yooj yim rau kev tsim cov khoom. Feem ntau siv hauv phom thiab riam phom, foob pob hluav taws, tsheb tub rog, cov cuab yeej siv dav hlau, cov khoom siv tub rog, cov cuab yeej siv dav hlau thiab lwm yam ntawm ntau yam.
30CrMnSiA tus qauv thawj coj: kev siv GB 3531-2014.
30CrMnSiA steel phaj loj, zoo li, hnyav thiab tso cai sib txawv:
1, qhov loj, cov duab thiab qhov sib txawv ntawm cov hlau phaj yuav tsum ua raws li cov kev cai ntawm GB / T709.
2, Thickness sib txawv yuav tsum ua raws li GB / T709 chav kawm B sib txawv raws li qhov xav tau ntawm qhov kev thov sab, kuj tuaj yeem xa raws li GB / T709 chav kawm C sib txawv.
3, Theoretical hnyav ntawm steel phaj yog xa, thiab cov thickness siv rau theoretical weighting yog tus lej nruab nrab ntawm qhov siab tshaj plaws thickness thiab yam tsawg kawg nkaus thickness pub rau steel phaj. Qhov ceev ntawm cov hlau yog 7.85g / m³.
30CrMnSiA tus me nyuam lub xeev yog feem ntau normalised, annealed, tempered ntawm kub kub los yog xa tsis kho cua sov.
