Iloiloga o meatotino ma vailaʻau faʻapipiʻi o le 20CrMnTi malulu-tosina paipa uʻamea seamless

20CrMnTi uamea ua taʻua o gear sila, ma le tele o vaega faaaogaina 20CrMnTi.

20CrMnTipaipa u'amea lamolemolee mafai ona vaevaeina i ni ituaiga se tolu: toso malulu, ta'ai vevela mapaipa u'amea su'esu'e malulu malulu, faatasi ai ma manaoga eseese ma faiga eseese.Ae ui i lea, o nisi iunite e faʻaogaina le uamea lapotopoto e gaosia ai vaega e aunoa ma le mafaufauina o le sui o paipa uʻamea.Suia 20CrMnTi malulu-tosi paipa uʻamea seamless ma 20CrMbTi lapotopoto uʻamea e le gata e faasaoina mea mata ma itula faigaluega, ae faʻaitiitia ai foi tau ma faʻateleina le tauvaga maketi.20CrMnTi ma 30CrMnSiA malulu-tosi seamless paipa uamea carburized uʻamea lelei, hardenability maualuga, malu ma ofuina-tetee luga ma le totonugalemu pe a uma carburizing ma quenching, maualuga maualalo-vevela aafiaga faigata, weldability feololo, ma machinability lelei ina ua uma normalizing.20CrMnTipaipa u'amea fa'a'a'alili mālūlūe masani ona maualalo le carbon carbon ma le carbon content of 0.17% - 0.24%.E fa'aaogaina lautele i ta'avale e gaosia ai mea fa'asalalau.E feololo hardenable carburized sila carbon, medium CrMnTi sila, ma hardenability maualuga.I lalo o le tulaga o le faʻamautinoaina o le faʻamalosi, e maualuga le malosi ma le faʻamalosi, aemaise lava le maualuga o le vevela o le aʻafiaga.20CrMnTi luga carburized ma uamea malo.Machinability lelei, deformation laʻititi i gaioiga faʻapitoa, ma le vaivai lelei.Fa'amoemoega: mo mea fa'aoga, fa'amau, vaega Piston, ma isi mea fa'aoga mo vaega fa'apitoa eseese o ta'avale ma va'alele.

20CrMnTi tulaga: GB/T 3077-1988

Uiga ma le lautele o le faaaogaina o20CrMnTi tosoina malulu uamea paipa:

E faʻaaogaina e gaosia ai vaega taua ma se vaega e itiiti ifo i le 30mm e maualuga le saoasaoa, feololo poʻo le mamafa o uta, aʻafiaga ma feteʻenaʻiga, e pei o uʻamea, mama mama, faʻalava faʻalava, ma isi.

Fa'ata'ita'iga tele: fa'ata'ita'iga avanoa avanoa e 15mm

Faʻamatalaga faʻamaʻi vevela ma fausaga metallographic o le 20CrMnTi toso malulu faʻafefe uamea paipa:

Fa'amatalaga o togafitiga vevela: tineia: 880 ℃ mo le taimi muamua, 870 ℃ mo le taimi lona lua, suau'u malulu;Temper 200 ℃, malulu vai ma malulu ea.

20crmnti uamea paipa o se auala hardenability uamea, lea e lelei hardenability ona o le alloying tele o Cr, Mn ma Ti.O le lautele taua o le tineia o suauu e tusa ma le 40mm;Ina ua uma le carburizing ma tineia, e maualuga le ofuina tete'e ma maualuga toughness, aemaise lava maualalo vevela aafiaga faigata;O le uamea o loʻo i ai le faʻagasologa lelei o le carburizing, o le tuputupu aʻe o saito laiti, tineia saʻo ma le faʻaleagaina laiti.20CrMnTi uʻamea e mafai ona faʻaaogaina e gaosia ai galuega mamafa vaega carburized ma vaega e itiiti ifo i le 30 ℃, ma e mafai ona tatalia le saoasaoa maualuga, avega feololo poʻo le mamafa o le mamafa, aʻafiaga ma feteʻenaʻiga, e pei o mea faʻaoga, mea faʻapipiʻi, mama mama, mama koluse, pipii lima. , anufe, ma isi.

O le vailaʻau vailaʻau o le paipa uʻamea 20crmnti e aofia ai le carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P ma le chromium Cr.20crmnti paipa uʻamea faiga gaosiga: uamea carbon, faauma taʻavale, non-oxidation togafitiga vevela susulu (NBK setete), suʻega le faʻaleagaina, uamea paipa puipui totonu ua fufuluina ma meafaigaluega faapitoa ma fufulu i lalo o le mamafa maualuga, suauu anti-ele i luga o le paipa uamea o togafitia mo le puipuia o le ele, ma o ufiufi i pito uma e lua e togafitia mo le puipuia o le pefu.20crmnti paipa uʻamea foliga: o le puipui totonu ma fafo o le paipa uamea e maualuga le saʻo ma maualuga maeʻa, o le paipa uʻamea e leai se oxide layer pe a uma togafitiga vevela, o le puipui totonu e maualuga le mama, o le paipa uamea e maualuga le mamafa, e le punou malulu e le deform, ma le faalauteleina ma le fa'amafolafola e leai ni ta'e.
