Iindidi ezi-4 zensimbi

Intsimbi ihleliwe kwaye ihlelwe ngamaqela amane: i-carbon steels, Amaqhekeza amdaka, Isixhobo se-stails esingenasiseko

Chwetheza 1-I-carbon steels

Ngaphandle kwikharbon kunye nentsimbi, amanqanaba e-carbon aqukethe kuphela izixa zamanye amacandelo. I-carbon stiels zezona zixhaphakileyo zamabakala amane ensimbi, i-akhawunti ye-90% yemveliso yentsimbi! I-carbon stiel ihlelwe kwiqela elithathu le-subgroups esekwe kwinani lekhabhoni kwintsimbi:

l i-carbon ephantsi i-steels / i-tils ethobekileyo (ukuya kwi-0.3% ye-carbon)

I-l cobon carbon steels (0.3-0.6% ikhabhoni)

l ikharbon ephezulu ye-stebon (ngaphezulu kwe-0.6% yekhabhoni)

Iinkampani zihlala zivelisa ezi ndawo zininzi zininzi kuba zingabizi kakhulu kwaye zinamandla ngokwaneleyo ukuba zisetyenziswe kwakhiwa olukhulu.

 

Uhlobo 2-Amaqhekeza amdaka

I-alloy steels yenziwa ngokudibanisa intsimbi ngolwabiwo olongezelelweyo njenge-nickel, ubhedu, i-chromium kunye / okanye ialuminiyam. Ukudibanisa ezi zinto kuphucula amandla, ukunganyangeki, ukumelana nokucoca kunye noomancili kwentsimbi.

 

Uhlobo 3-Izitya ezingenanto

Inqanaba lensizi engenasitali labelwe nge-10 ukuya kwi-20% ye-chromium kunye ne-nilicon, isilicon, i-manganese, kunye nekhabhoni. Ngenxa yesakhono sabo sokukhulisa ukuze siphile kwimozulu embi yezi ntaka zinokunganyangeki kakhulu kwaye zikhuselekile ukuba zisebenzise ulwakhiwo lwangaphandle. Amabakala ensizi engenanto asetyenziswa rhoqo kwizixhobo zombane.

Umzekelo, intsimbi engathandekiyo ifunwa ngokubanzi emva kokukwazi ukumelana nokusingqongileyo ngelixa igcina izinto zombane zikhuselekile.

Ngelixa amabakala ahlukeneyo ensimbi, kuquka intsimbi engama-304, yiba nendawo kwizakhiwo, intsimbi engenasimo idla ngokufunwa rhoqo emva kwepropathi yakhe yococeko. Ezi mpahla zifumaneka ngokubanzi kwizixhobo zezonyango, imipheliso, iinqanawa zoxinzelelo, izixhobo zokusika kunye noomatshini bokulungisa ukutya.

 

Uhlobo 4-Isixhobo se-steels

Isixhobo se-tils, njengoko igama licebisa, i-Excel kwizixhobo zokusika kunye nokuntywila. Ubukho be-tungsten, iMolybdenum, Cobandi kunye ne-dadium inceda ukuphucula ukumelana kobushushu kunye nokuqina ngokubanzi. Kwaye ngenxa yokuba bebambe imilo yabo nokuba basebenzise kakhulu, zezona zixhobo zikhethiweyo zezixhobo zesandla.

 

Ukuhlelwa kwensimbi

Ngaphaya kwamaqela amane, intsimbi inakho ukuqhagamshelwa ngokusekwe kwiinguqu ezahlukeneyo kubandakanya:

Ukuqulunqwa: Uluhlu lwe-carbon, isabelo, esingenanto, njl.

Ukugqiba kwendlela: Ishushu egqunywe, ingqengqeleka ibandayo, ingqwa egqityiweyo, njl.

Indlela yemveliso: Iziko lombane, EQhubekayo, njl.

UMSEBENZI WAMABALI: I-Ferric, i-Pearlic, Martiaticic, njl.

Amandla omzimba: kwimigangatho ye-ASTM

Inkqubo ye-Oxidation ye-De-Oxidation: ebulewe okanye ibulewe

Unyango lobushushu: I-Anneled, ngomsindo, njl.

Umgangatho osemgangathweni: umgangatho worhwebo, umgangatho wenqanawa, ukuzoba umgangatho, njlnjl.

 

Leliphi elona nqanaba lilungileyo lensimbi?

Akukho nqanaba lensimbi ye-jikelele, njengenqanaba lentsimbi eligqibeleleyo lesicelo lixhomekeke kwizinto ezininzi, ezinjengokusetyenziswa kwenjongo, kunye nemida yezemali.

Amabakala ensimbi asetyenziswa rhoqo kwaye athathwa njengoluhlu oluphezulu kuhlobo ngalunye kubandakanya:

I-Carbon Steels: A36, A529, i-A572, 1045, ne-4130

I-Alloy Steels: 4140, 4150, 4340, 9310, kunye ne-52100

I-Staives engenasibala: 304, 316, 410, kunye ne-420

Isixhobo se-Steels: D2, H13, NO M2

 

UJindai yiqela eliphambili lentsimbi elinokunikezela onke amabakala ngentsimbi yentsimbi kwi-Coil, iphepha, ityhubhu, i-thanes, i-tees, i-tees, kwaye uya kwaneliswa yimveliso.
