1. Peta kuti ugadzirise chinangwa chendima iyi
H13 die simbiinoshandiswa kugadzira madhiri ekugadzira ane simba guru, madhiri ekupisa anobuda, madhiri ekugadzira akanyatsogadzirwa; madhiri ekugadzira anoshandiswa pakugadzira aruminiyamu, mhangura nesimbi dzawo.

Ndiyo nzira yekuisa simbi yeH13 air quench hardening hot work die steel kubva kuUnited States. Hunhu hwayo nekushandiswa kwayo zvakafanana nesimbi ye4Cr5MoSiV, asi nekuda kwehuwandu hwayo hwevanadium hwakawanda, kushanda kwayo kwepakati nepakati (600 degrees) kuri nani pane simbi ye4Cr5MoSiV. Isimbi inomiririra ine mashandisirwo akasiyana-siyana musimbi yekushanda inopisa.
2. Zvinhu Zvikuru
Simbi yakanyungudutswa neElectroslag, simbi iyi inogona kuomarara zvakanyanya uye inogona kupwanyika nekupisa, simbi iyi ine kabhoni nevanadium yakawanda, inogona kusimba zvakanyanya pakupfeka, inogona kusimba zvishoma, uye inogona kusimba zvakanyanya pakupisa. Pakupisa kwakanyanya, ine simba riri nani uye yakaoma, inogona kusimba zvakanyanya pakupfeka, ine hunhu hwakanaka hwemakanika uye inogona kusimba zvakanyanya pakudziya.
3. Kuumbwa kwemakemikari esimbi
Simbi yeH13 isimbi yeC-Cr-Mo-Si-V, iyo inoshandiswa zvakanyanya pasi rose. Panguva imwe chete, nyanzvi dzakawanda dzinobva kunyika dzakasiyana dzakaita tsvakiridzo yakakura pamusoro payo uye dziri kutsvaga kuvandudzwa kwemakemikari. Simbi inoshandiswa zvakanyanya uye ine hunhu hwakanaka, hunonyanya kutsanangurwa nemakemikari ari musimbi. Ehe, zvinhu zvisina kuchena musimbi zvinofanirwa kuderedzwa. Mamwe data anoratidza kuti kana Rm iri 1550MPa, huwandu hwesarufa muzvinhu zvinodzikiswa kubva pa0.005% kusvika pa0.003%, izvo zvichawedzera kusimba kwemhedzisiro neinenge 13J. Zviri pachena kuti NADCA 207-2003 standard inoti huwandu hwesarufa musimbi yeH13 yepamusoro hunofanira kunge huri pasi pe0.005%, nepo huwandu hwesarufa hwepamusoro huchifanira kunge huri pasi pe0.003%S uye 0.015%P. Kuumbwa kwesimbi yeH13 kunoongororwa pazasi.

Kabhoni: American AISI H13, UNS T20813, ASTM (yazvino vhezheni) H13 uye FED QQ-T-570 H13 simbi ine kabhoni ye (0.32~0.45)%, inova ndiyo kabhoni yakawanda kupfuura dzose.Simbi dzeH13. Yakafara. Huremu hwekabhoni hweGerman X40CrMoV5-1 ne1.2344 i (0.37~0.43)%, uye huwandu hwekabhoni hwakamanikana. MuGerman DIN17350, huwandu hwekabhoni hweX38CrMoV5-1 i (0.36~0.42). Huremu hwekabhoni hweSKD 61 muJapan i (0.32~0.42). Huremu hwekabhoni hwe4Cr5MoSiV1 neSM 4Cr5MoSiV1 muGB/T 1299 yenyika yangu neYB/T 094 i (0.32~0.42)% uye (0.32~0.45)%, izvo zvakafanana neSKD61 neAISI H13, zvichiteerana. Zvikuru, zvinofanira kutaurwa kuti huwandu hwekabhoni hwesimbi yeH13 muNorth American Die Casting Association NADCA 207-90, 207-97 uye 207-2003 hwakatsanangurwa se (0.37~0.42)%.

Simbi yeH13 ine 5% Cr inofanira kunge yakasimba, saka C yayo inofanira kuchengetedzwa padanho rinoumba huwandu hushoma hwe alloy C compounds. Woodyatt naKrauss vakataura kuti paFe-Cr-C ternary phase diagram pa870℃, nzvimbo yesimbi yeH13 iri nani panosangana austenite A ne (A+M3C+M7C3) three-phase regions. C inoenderana neC inenge 0.4%. Mufananidzo uyu wakaratidzawo kuwedzera kwehuwandu hweC kana Cr kuwedzera huwandu hweM7C3, uye simbi dzeA2 neD2 dzine resistance yakakura yekupfeka kuti dzienzaniswe. Zvakakoshawo kuchengetedza C yakaderera kuti Ms point yesimbi itore tembiricha yakakwira (Ms yesimbi yeH13 inowanzotsanangurwa se340℃), kuitira kuti simbi ikwanise kudzimwa kusvika patembiricha yemukamuri. Wana chimiro che alloy C compound chinonyanya kuumbwa ne martensite pamwe nehuwandu hushoma hwe residual A uye residual uniform distribution, uye uwane chimiro che martensite chakafanana mushure mekudziya. Dzivisa kushandura austenite yakawandisa yakachengetwa patembiricha yekushanda kuti ikanganise mashandiro ekushanda kana kushanduka kwebasa. Aya huwandu hudiki hweaustenite yakachengetwa hunofanira kushandurwa zvachose mumaitiro maviri kana matatu ekudziya mushure mekudzima. Nenzira, zvinoratidzwa pano kuti chimiro chemartensite chinowanikwa mushure mekudzima simbi yeH13 ilath M + huwandu hushoma hweflake M + huwandu hushoma hweA yasara. Macarbide akanaka kwazvo ealloy anowira palath M mushure mekudziya. Nyanzvi dzemuno dzakaitawo mamwe mabasa.
