Into ebizwaumbhobho wentsimbi yengxubevangekukongeza ezinye izinto ze-alloy kwisiseko se-carbon steel, njengeSi, Mn, W, V, Ti, Cr, Ni, Mo, njl., ezinokuphucula amandla, ukuqina, ukuqina, ukuwelda, njl. intsimbi.ukusebenza.Insimbi ye-alloy inokuthi ihlelwe ngokwemixholo yezinto ze-alloy, kunye nemveliso ye-industrial kunye nobomi, insimbi ye-alloy iya kusetyenziswa kumashishini athile, kwaye iqhelekile ukwahlula ngokwenjongo.
Ukuhlelwa ngokomxholo wezinto ezixutywayo
Insimbi ye-alloy ephantsi: inani elipheleleyo le-alloy lingaphantsi kwe-5%;
Insimbi ye-alloy ephakathi: inani elipheleleyo le-alloy yi-5 ~ 10%;
Insimbi ephezulu ye-alloy: inani elipheleleyo le-alloy liphezulu kune-10%.
Ukuhlelwa ngokwenjongo
I-alloy structural steel: i-alloy structural iron ephantsi (eyaziwa ngokuba yintsimbi eqhelekileyo ephantsi);i-alloy carburizing steel, i-alloy ecinyiweyo kunye nentsimbi epholileyo, i-alloy spring steel;ibhola ethwele intsimbi
Isixhobo sensimbi ye-alloy: i-alloy cutting tool yensimbi (kubandakanywa nentsimbi ephantsi yokusika i-alloy, i-high-speed steel);i-alloy die steel (kubandakanya intsimbi yokufa ebandayo, intsimbi eshushu yokufa);intsimbi yezixhobo zokulinganisa
Intsimbi yokusebenza ekhethekileyo: insimbi engenasici, intsimbi enganyangeki ukushisa, intsimbi engagugiyo, njl.
Inombolo yentsimbi yealloyi
I-alloy ephantsi yamandla aphezulu ensimbi yesakhiwo
Igama layo le-brand licwangciswe ngokulandelelana ngamalungu amathathu: unobumba we-pinyin waseTshayina (Q) omele indawo yesivuno, ixabiso lomda wesivuno, kunye nesimboli somgangatho womgangatho (A, B, C, D, E).Umzekelo, i-Q390A ithetha i-alloy low-alloy high-sight-high-high-streystructural iron enamandla emveliso σs=390N/mm2 kunye nomgangatho A.
Ingxubevange yentsimbi yesakhiwo
Igama layo lebrand linamacandelo amathathu: "amadijithi amabini, iisimboli zento ezilishumi + amanani".Amanani amabini okuqala amele amaxesha angama-10,000 i-avareji ye-carbon mass fraction kwintsimbi, uphawu lwento lubonisa i-alloying elements equlethwe kwintsimbi, kwaye amanani emva kwesimboli ye-element abonisa amaxesha angama-100 i-avareji yeqhekeza le-elementi.Xa i-avareji yobunzima beqhezu lezinto ezidibanisayo ingaphantsi kwe-1.5%, ngokubanzi kuphela izakhi ezibonisiweyo kodwa hayi ixabiso lamanani;xa i-avareji ye-mass fraction ≥1.5%, ≥2.5%, ≥3.5%, ..., i-2 kunye ne-3 iphawulwe ngokuhambelanayo emva kwezinto ezixutywayo , 4, ...Umzekelo, i-40Cr inomlinganiselo we-carbon mass fraction Wc = 0.4%, kunye ne-avareji ye-chromium mass fraction WCr <1.5%.Ukuba intsimbi yezinga eliphezulu, yongeza "A" ekupheleni kwebakala.Umzekelo, intsimbi ye-38CrMoAlA yeyomgangatho ophezulu womgangatho ophezulu we-alloy structural steel.
Ukuqengqeleka kwentsimbi
Yongeza "G" (unobumba wokuqala we-pinyin yesiTshayina yegama elithi "roll") phambi kwegama lebrand, kwaye inani elisemva kwalo libonisa iwaka eliphindwe kaninzi kwiqhekeza le-chromium, kwaye iqhekeza elikhulu lekhabhoni aliphawulwanga. .Umzekelo, i-GCr15 intsimbi yintsimbi ejikelezayo eneqhezu lobunzima obuphakathi kwechromium WCr = 1.5%.Ukuba intsimbi ethwele ichromium iqulethe izinto ezixubekileyo ngaphandle kwechromium, indlela yokubonakalisa ezi zinto iyafana naleyo yentsimbi yolwakhiwo lwealloyi ngokubanzi.Iintsimbi eziqengqelekayo eziziintsimbi eziziintsimbi ezikumgangatho ophezulu, kodwa "A" ayongezwa emva kwebakala.
I-alloy isixhobo sentsimbi
Umahluko phakathi kwendlela yokubala yolu hlobo lwentsimbi kunye nentsimbi yesakhiwo se-alloy kukuba xa i-Wc <1%, idijithi enye isetyenziselwa ukubonisa amaxesha angamawaka ubukhulu beqhekeza lekhabhoni;xa ubunzima bekhabhoni ≥1%, ayiphawulwanga.Umzekelo, intsimbi ye-Cr12MoV inomlinganiselo we-carbon mass fraction ye-Wc = 1.45% ~ 1.70%, ngoko ayiphawulwanga; i-avareji yobunzima beqhekeza le-Cr yi-12%, kwaye amaqhezu obunzima be-Mo kunye ne-V omabini angaphantsi kwe-1.5% .Omnye umzekelo yintsimbi ye-9SiCr, i-avareji ye-Wc = 0.9%, kunye ne-WCr ephakathi ngu <1.5%.Noko ke, intsimbi yesixhobo esinesantya esiphezulu ihlukile, kwaye i-avareji yayo ye-carbon mass fraction ayiphawulwa nokuba ingakanani na.Kuba Isixhobo sensimbi yensimbi kunye nesantya esiphezulu sentsimbi yintsimbi yodidi oluphezulu, akukho mfuneko yokumakisha "A" emva kwebakala layo.
Insimbi engenasici kunye nentsimbi ekwazi ukumelana nobushushu
Inani eliphambi kolu hlobo lwebakala lensimbi libonisa amaxesha angamawaka e-carbon mass fraction.Umzekelo, i3Crl3 intsimbi ithetha ukuba i-avareji yobunzima beqhezu Wc=0.3%,kunye neqhezu lobunzima eliphakathi WCr =13%.Xa iqhezu lobunzima lekhabhoni Wc ≤ 0.03% kunye neWc ≤ 0.08%,iboniswa ngu "00" kunye "0" phambi kophawu, njengentsimbi ye-00Cr17Ni14Mo2,0Cr19Ni9, njl.
