Daawaha steel

In la doorto waxyaabaha la for soo saaridda ee alaabta birta ah astaamaha dhowr in la tixgeliyo, oo ay ku jiraan modulus ee rigidity. Tani index xasaas ah dhismaha ku xiran tahay oo kaliya on nooca wax laga xubno awoodda - howlgala, mab, taarikada flat, iwm

modulus ugu sareeya ee rigidity waa bir, taas oo iyana waa laba nooc ee Halabuurka kiimikada ay. Waa midda koowaade, steel daawaha this, kaas oo si gaar ah daray xubno alloying si aad u hesho wax kasta oo guryaha loo baahan yahay.

xubno ka ugu weyn ee ah in ay saamayn ku sifooyinka steel - waa carbon, Silicon iyo manganese. Carbon halka laga kordhinayo ay ka kooban tahay ka dhigaa bir xoog iyo adag, halka yareynta ay ductility. Silicon waxaa maamula sida wakiilka deoxidizing ah, laakiin haddii ay ka kooban tahay waa in ka badan boqolkiiba hal badan dilaacda weldability ee steel: Weld waa debcaan. A waa element ah sida manganese hagaajinaysaa brittleness qabow iyo qalleyf bir, sidoo kale isagoo deoxidizer wanaagsan.

Sida caadiga ah, marka lagu daro birta iyo carbon, waxaa lagu darayaa in qayb ka mid kaliya, steel si alloyed tilmaamay inay tahay saddex-qayb, afar ka kooban, iyo wixii la mid ah. D. Mararka qaarkood waxaa kala duwan yihiin horyaalka ee element ka alloying, sida chromium, chromium-nickel, iwm hromonikelmolibdenovaya

Daawaha steel ka kooban in ka badan boqolkiiba hal chromium ama nickel. Haddii ay tahay joogo in ka badan 0.5% of vanadium, titanium, molybdenum, niobium, nitrogen, copper, iwm, Waxaa loo arkaa by xubno daawaha kuwaas.

Ku xiran tahay tirada ka mid ah qaybaha daray, steel daawaha u qaybsan yahay ee Banii- soo socda:

- bir-daawaha sare, kuna waari dhexdeeda content guud ee xubno alloying ka yar yahay boqolkiiba toban;

- srednelegirovannoj - wax ka badan boqolkiiba siddeed,

- bir, taas oo element ka mid ah oo kaliya ayaa lagu darayaa leh ka kooban yahay xadka sare ee aan ka badnayn boqolkiiba laba low-alloyed.

Sida caadiga ah, xubno ka alloying ah aad bay u weynaan qiimaha birta, gaar ahaan tan iyo xubno ka mid ah waxaa lagu daray in ay isu yihiin biraha qaali yari. Iyadoo la raacayo, ay intaa dheer in steel waa in si taxadar leh ku xeeldheer.

steel Alloyed leeyahay calaamadaha soo socda: labada lambar ee koobaad ayaa tilmaamaya content carbon ah (boqol meelood ee boqolkiiba a), xarfaha muujinaya keeneysa la raaciyay alloying lambar element iyaga ka dib - content ee element this boqolkiiba. xarafka "A", taas oo u taagan dhamaadka habka sixitaanka, in birta tayo sare leh content hooseeyo of fosfooraska, iyo baaruud.

kala duwanaansho kale oo Halabuurka kiimikada bir ah - carbon. Its sababta oo ah xog iyo cheapness ee wax soo saarka si isa soo taraysa loo isticmaalo warshadaha badan.

Mid ka mid ah isticmaalka loogu talagalay of steel waa adeegsigeeda soo saaridda ee lagu qiyaaso iyo jarida qalab, qaybaha mishiinka, dhinto la lahayo ku qabow iyo kulul.

steel Tool oo kiiska daawaha, iyo carbon, oo ku xiran sharciyada maamula martida, waayo, mid kasta oo alaabta birta gaar ah u baahan tahay in ay isticmaalaan bir isagoo Halabuurka kiimikada gaar ah.

. Tusaale ahaan, waayo, qalabka qalliinka, oo dhoollatus, chisels, dubbayaal, screwdrivers, miinshaaro, Foornada, iwm isticmaalo steel category gaar ah --daawaha sare,-xawaaraha sare. Waxay leedahay engegnaantiinna sare, iska caabin ah kulaylka iyo iska caabin abrasion. Kuwani sifooyin u gaar ah waxaa laga heli by ku daray alloying gaar ah carbide tungsten, iyo sidoo kale daaweynta kulaylka adag.

Waayo, dubbihii, dhinto kulul iyo qabow, wasakhahaasi iyo al. Fasalada steel isticmaalay sida H6VF, 9x, 5HNM iwm
