Izvo zvinonzialloy simbi pombikuwedzera mamwe alloy element pahwaro hwekabhoni simbi, seSi, Mn, W, V, Ti, Cr, Ni, Mo, nezvimwewo, izvo zvinogona kuvandudza kusimba, kuoma, kuoma, kusimba, nezvimwe. simbi.performance.Alloy simbi inogona kuverengerwa zvinoenderana nezviri mukati meiyo alloy zvinhu, uye mukugadzirwa kwemaindasitiri uye hupenyu, alloy simbi ichashandiswa mune chaiwo maindasitiri, uye zvakajairika kurongedza zvinoenderana nechinangwa.
Classification maererano nezviri mukati me alloying elements
Yakaderera alloy simbi: iyo yakazara huwandu hwealloy isingasviki 5%;
Medium alloy simbi: huwandu hwehuwandu hwealloy ndeye 5 ~ 10%;
High alloy simbi: iyo yakazara huwandu hwealloy yakakwirira kupfuura 10%.
Kuronga maererano nechinangwa
Alloy structural simbi: yakaderera alloy structural simbi (inozivikanwawo seyakajairwa yakaderera alloy simbi);alloy carburizing simbi, alloy quenched uye tempered simbi, alloy spring steel;bhora rinotakura simbi
Alloy tool simbi: alloy cutting tool simbi (kusanganisira yakaderera alloy yekucheka simbi, high-speed steel);alloy die simbi (kusanganisira inotonhora die simbi, inopisa die simbi);simbi yekuyeresa maturusi
Special performance simbi: Stainless simbi, heat-resistant simbi, kupfeka-resistant simbi, etc.
Alloy simbi nhamba
Low alloy high simba structural simbi
Zita rechiratidzo charo rakarongwa muhurongwa nezvikamu zvitatu: bhii reChinese pinyin (Q) rinomiririra goho, kukosha kwemuganho wegoho, uye chiratidzo chegiredhi remhando (A, B, C, D, E).Semuenzaniso, Q390A inoreva yakaderera-alloy yakakwirira-yakasimba simbi yekugadzira ine goho simba σs=390N/mm2 uye yemhando giredhi A.
Alloy structural simbi
Zita rayo rechiratidzo rine zvikamu zvitatu: "manhamba maviri, gumi element zviratidzo + nhamba".Mavara maviri ekutanga anomiririra ka10,000 nguva yeavhareji kabhoni misa chikamu musimbi, chiratidzo chechinhu chinoratidza alloying zvinhu zviri musimbi, uye manhamba ari kuseri kwechiratidzo chechinhu anoratidza ka100 avhareji yechikamu chechikamu.Kana avhareji yehupamhi chidimbu chealloying zvinhu chiri pasi pe1.5%, kazhinji zvinhu chete ndizvo zvinoratidzwa asi kwete kukosha kwenhamba;apo chikamu chepakati chemazana chiri ≥1.5%, ≥2.5%, ≥3.5%, ..., 2 uye 3 inofananidzwa yakanyorwa kuseri kwealloying elements , 4, ...Semuyenzaniso, 40Cr ine avhareji yekabhoni mass fraction Wc=0.4%, uye avhareji yechromium mass fraction WCr<1.5%.Kana iri yepamusoro-giredhi yepamusoro simbi, wedzera "A" pakupera kwegiredhi.Semuenzaniso, 38CrMoAlA simbi ndeyepamusoro-giredhi yepamusoro-mhando alloy structural simbi.
Kukungurutsa simbi
Wedzera "G" (bhii rekutanga reChinese pinyin yezwi rekuti "roll") pamberi pezita rechiratidzo, uye nhamba iri kumashure kwayo inoratidza kakapetwa chiuru chikamu chekromium, uye chikamu chekabhoni hachina kunyorwa. .Semuyenzaniso, GCr15 simbi isimbi inokunguruka ine avhareji yechikamu chekromium WCr = 1.5%.Kana chromium inotakura simbi iine alloying zvinhu zvisiri chromium, mataurirwo emaitiro ezvinhu izvi akafanana neye general alloy structural simbi.Rolling bearing steels ese akakwirira-giredhi emhando yepamusoro simbi, asi "A" haiwedzerwe mushure megiredhi.
Alloy tool simbi
Musiyano uripo pakati penhamba nzira yerudzi urwu rwesimbi uye alloy structural simbi ndeyokuti kana Wc <1%, digit imwe inoshandiswa kuratidza churu chakapetwa kaviri chikamu chekabhoni;kana chikamu chikuru chekabhoni chiri ≥1%,hachina kunyorwa.Semuyenzaniso, Cr12MoV simbi ine avhareji kabhoni misa chikamu cheWc = 1.45% ~ 1.70%, saka haina kunyorwa; chikamu chepakati cheCr chiri 12%, uye zvikamu zvehuwandu zveMo neV zvese zviri pasi pe1.5% .Mumwe muenzaniso i9SiCr simbi, avhareji Wc = 0.9%, uye avhareji WCr i <1.5%.Zvisinei, high-speed tool simbi inosiyana, uye avhareji yayo kabhoni mass fraction haina kunyorwa kunyangwe ikawanda sei.Nekuti alloy tool simbi uye high-speed tool simbi ndeyepamusoro-giredhi yemhando yepamusoro simbi, hapana chikonzero chekumaka "A" mushure megiredhi rayo.
Simbi isina tsvina uye simbi inodzivirira kupisa
Nhamba iri pamberi pemhando iyi yegiredhi yesimbi inoratidza kane chiuru chikamu checarbon mass fraction.Semuyenzaniso, 3Crl3 simbi inoreva kuti avhareji yehupamhi chidimbu Wc = 0.3%, uye avhareji yehupamhi chidimbu WCr = 13%.Kana chikamu chehuremu checarbon Wc ≤ 0.03% uye Wc ≤ 0.08%, chinoratidzwa ne "00" uye "0" pamberi pechiratidzo, senge 00Cr17Ni14Mo2,0Cr19Ni9 simbi, nezvimwe.
