Ingxubevange steel

Xa ukhetha izinto lokuvelisa iimveliso etyhidiweyo iimpawu ezininzi ukuqwalaselwa, kuquka modulus of ngqongqo. Oku noshowo index ezingenabuzaza kuxhomekeke kuphela kuhlobo umbandela apho iziqalelo ngamandla - stringers, izakhelo, iipleyiti flat, njl

Le modulus ephezulu ngqongqo na intsimbi, nto leyo ke iintlobo ezimbini kumafa yemizimba yethu. Okokuqala, lo intsimbi ingxubevange, esongeza ngokukodwa iziqalelo alloying ukufumana naziphi na iimpawu eziyimfuneko.

Iimpawu eziphembelela iimpawu ngentsimbi - le carbon, lesilicon kunye manganese. Carbon ngelixa sisenyusa nokuqulethileyo yenza ngentsimbi esomelela nzima, ngoxa kuncitshiswa ductility yayo. Silicon ilawulwa njenge arhente deoxidizing, kodwa ukuba umxholo wayo ngaphezu kwesinye ekhulwini eninzi kuguga ukuba weldability ngentsimbi: i weld-nkum. A yeyona nto yemanganizi uphucula brittleness ukubanda ubulukhuni ngentsimbi, nayo ekubeni deoxidizer elungileyo.

Ngokuqhelekileyo, ukongeza ngentsimbi carbon, idityaniswe naliphi na icandelo elinye, intsimbi exutyiweyo ukuze sibenokubizwa njengendawo njengenxalenye ezintathu,-icandelo ezine, njalo njalo. D. Maxa wambi oku kuyahluka ukuba isihloko element alloying, ezifana chromium, chromium-nickel, njl hromonikelmolibdenovaya

Yenza ingxubevange steel iqulathe ngaphezu kwesinye ekhulwini chromium okanye nickel. Ukuba ikhona ngaphezu kwe-0.5% of vanadium, titanium, molybdenum, ukrweco, initrogen, ikopolo, njl, Kuthathwa yi ezi zinto ingxubevange.

Ngokuxhomekeke kwinani kumacandelo wongezelela, ingxubevange sobhedu wohlulwe le subclasses zilandelayo:

- high-ingxubevange sentsimbi, apho isiqulatho olupheleleyo lweziqalelo alloying yi ekhulwini ngaphantsi kwe ezilishumi;

- srednelegirovannoj - hayi ngaphezulu kwe ezisibhozo per cent;

- eziphantsi exutyiweyo intsimbi, apho omnye kuphela element kongezwe ngemixholo nelona qondo liphezulu hayi ngaphezulu kwe amabini ekhulwini.

Ngokuqhelekileyo, izinto alloying kuyandisa kakhulu iindleko ngentsimbi, ingakumbi ukusukela adityaniswe ezinye izinto e ngokwabo iintsimbi awukho eninzi. Ngako oko, ngaphezu kwabo ngentsimbi kufuneka lusekelwe ngenyameko.

steel exutyiweyo abe ngamanqaku zilandelayo: amanani amabini ebonisa isiqulatho carbon (hundredths of a ekhulwini), oonobumba zibonisa kwemiqathango wongezelela alloying digit element emva kwabo - umxholo lwesi sakhi njengepesenti. Le leta "A", nto leyo imi ekupheleni indlela zokumakisha, ukuba high steel umgangatho ezinomthamo esezantsi phosphorus nesulfure.

Enye indlela kwemichiza ubume ngentsimbi - carbon. Its ngenxa ekunyaniseni cheapness zemveliso ngokwandileyo esetyenziswa kwimizi-mveliso emininzi.

Enye ukusetyenziswa ekujongwe sobhedu ukusetyenziswa kwayo ekwenziweni wokulinganisa ukusika izixhobo, izahlulo umatshini, ufela deformation ebandayo kunye nobushushu.

steel Tool and ingxubevange, ne-carbon, yaye ngokuxhomekeke kwimigaqo ilawulwa yi-guest, iimveliso ngamnye intsimbi ethile kufuneka basebenzise intsimbi ukuba sisincoko imichiza ethile.

. Umzekelo, ngokuba izixhobo zotyando, izilumkiso, zokutshweza, izando, ii-screwdriver, iisarha, hobs, njl wasebenzisa intsimbi udidi oluthile - high-ingxubevange,-high speed. It has yobulukhuni phezulu, ukumelana ubushushu kunye nokumelana lingonakali. Le propati ezizodwa afunyanwa ngokongeza alloying olukhethekileyo Tungsten khabhayithi, kwakunye unyango ubushushu enzima.

Kuba ihamile, iyafa ashushu nabandayo, jeli kunye al. Kumabakala steel ezifana H6VF, '9x', 5HNM njl
