1. Peta kugadzirisa chinangwa chendima ino
H13 simbi inofainoshandiswa kugadzira forging inofa ine high impact load, inopisa extrusion inofa, precision forging inofa;die-casting anofira aruminiyamu, mhangura uye alloys ayo.

Iko kuiswa kweH13 mhepo inodzima kuomesa inopisa basa die steel kubva kuUnited States.Zvimiro zvayo nemashandisirwo acho zvakangofanana neaya e4Cr5MoSiV simbi, asi nekuda kwepamusoro vanadium yemukati, tembiricha yayo yepakati (600 madhigirii) kuita kuri nani pane 4Cr5MoSiV simbi.Iri mumiririri wesimbi yegiredhi ine huwandu hwakawanda hwekushandisa mubasa rinopisa rinofa simbi.
2. Zvimiro
Electroslag simbi yakanyungudutswa, simbi ine kuomarara kwakanyanya uye nekupisa kupisa kuramba, simbi ine yakakwira yemukati kabhoni uye vanadium, yakanaka kupfeka kuramba, kusimba kusimba, uye kunaka kwekupisa.Pakupisa kwepamusoro, ine simba riri nani uye kuoma, kusimba kwepamusoro kupfeka uye kusimba, yakanakisa yakazara mekiniki zvivakwa uye yakanyanya kudzikama kuramba kugadzikana.
3. Mushonga wemakemikari wesimbi
H13 simbi isimbi yeC-Cr-Mo-Si-V, iyo inoshandiswa zvakanyanya munyika.Panguva imwecheteyo, nyanzvi dzakawanda kubva kunyika dzakasiyana dzakaita tsvakurudzo yakawanda pamusoro payo uye dziri kuongorora kuvandudzwa kwemakemikari.Simbi inoshandiswa zvakanyanya uye ine hunhu hwakanakisa, inonyanya kutsanangurwa nekemikari yesimbi.Zvechokwadi, zvinhu zvisina kuchena musimbi zvinofanira kuderedzwa.Imwe data inoratidza kuti kana iyo Rm iri 1550MPa, iyo sarufa yemukati yezvinhu inodzikiswa kubva pa0.005% kusvika 0.003%, izvo zvinozowedzera kuoma kwemhedzisiro ne13J.Zviripachena, iyo NADCA 207-2003 yakajairwa inotaura kuti sulfur yemukati yepremium H13 simbi inofanira kunge iri pasi pe0.005%, nepo sulfur yemukati mepamusoro inofanira kunge iri pasi pe0.003%S uye 0.015% P.Kuumbwa kweH13 simbi kunoongororwa pasi apa.

Carbon: American AISI H13, UNS T20813, ASTM (iyo yazvino vhezheni) H13 uye FED QQ-T-570 H13 simbi ine kabhoni yemukati ye (0.32~0.45)%, inova yakanyanya kabhoni yemukati mese.H13 simbi.Wide.Iyo kabhoni yemukati yeGerman X40CrMoV5-1 uye 1.2344 ndeye (0.37 ~ 0.43)%, uye iyo kabhoni yemukati renji idiki.MuchiGerman DIN17350, iyo kabhoni yeX38CrMoV5-1 ndeye (0.36~0.42)%.Iyo kabhoni yemukati yeSKD 61 muJapan ndeye (0.32~0.42)%.Iyo kabhoni yemukati ye4Cr5MoSiV1 uye SM 4Cr5MoSiV1 munyika yangu GB/T 1299 uye YB/T 094 iri (0.32~0.42)% uye (0.32~0.45)%, akafanana neSKD61 neAISI H13, zvichiteerana.Kunyanya, zvinofanirwa kutaurwa kuti iyo kabhoni yemukati yeH13 simbi muNorth American Die Casting Association NADCA 207-90, 207-97 uye 207-2003 zviyero zvinotsanangurwa se (0.37 ~ 0.42)%.

H13 simbi ine 5% Cr inofanira kuva nehupamhi hwepamusoro, saka iyo C yemukati inofanira kuchengetedzwa pamwero unoumba zvishoma zve alloy C zvinosanganiswa.Woodyatt naKrauss vakaratidza kuti paFe-Cr-C ternary phase diagram pa 870 ℃, nzvimbo yeH13 simbi iri nani pakusangana kwe austenite A uye (A + M3C + M7C3) nzvimbo nhatu-chikamu.Izvo zvinoenderana neC zvemukati zvinenge 0.4%.Nhamba yacho yakaratidzawo kuwedzera kwehuwandu hweC kana Cr kuwedzera huwandu hweM7C3, uye maA2 uye D2 masimbi ane kukwirira kwekupfeka kwekuenzanisa.Izvo zvakakoshawo kuchengetedza yakaderera C zvemukati kuita kuti Ms point yesimbi itore tembiricha yakakwira (iyo Ms yeH13 simbi inowanzotsanangurwa se340 ℃), kuitira kuti simbi iyi igone kudzimwa kusvika kune tembiricha.Tora iyo alloy C chimiro chemukomboni chinonyanya kuumbwa nemartensite pamwe nediki diki reyakasara A uye yasara yunifomu kugovera, uye tora yunifomu inodziya martensite chimiro mushure mekudziya.Dzivisa kushandura yakawandisa yakachengetwa austenite pane tembiricha yekushanda kukanganisa kushanda kwekushanda kana deformation yeworkpiece.Izvi zvidiki zvidiki zvakachengetwa austenite zvinofanirwa kushandurwa zvakazara mumaviri kana matatu ekupisa maitiro mushure mekudzima.Nenzira, zvinoratidzwa pano kuti martensite maitiro akawanikwa mushure mekudzima kweH13 simbi ndeye lath M + shoma shoma yeflake M + shoma shoma yakasara A. Iyo yakanyanya kunaka alloy carbides inonaya pa lath M mushure mekupisa.Nyanzvi dzemudzimba dzakaitawo rimwe basa
