Ho hlahisoa lithane tse fetang limilione tse likete tse 1,5 tsa tšepe selemo le selemo, tse sebelisetsoang ho etsa lihlahisoa tse fapa-fapaneng, tse kang linale tsa ho rōka le maballo a mohaho bakeng sa mehaho e meholo.Tšepe ea carbon ke tšepe ea alloy e sebelisoang ka ho fetisisa, e etsang karolo ea 85% ea tlhahiso eohle ea US.Khabone ea sehlahisoa e maemong a 0-2%.Khabone ena e ama microstructure ea tšepe, e e fa matla a eona a tummeng le ho tiea.Li-alloys tsena li boetse li na le palo e nyane ea manganese, silicon le koporo.Tšepe e bonolo ke lentsoe la khoebo bakeng sa tšepe e bonolo e nang le carbon content ea 0.04-0.3%.
Tšepe ea carbon e ka aroloa ho latela sebopeho sa lik'hemik'hale le thepa ea sehlahisoa.Tšepe e bonolo le eona e oela sehlopheng sa tšepe e bonolo hobane e na le khabone e tšoanang.K'habone e tloaelehileng ha e na li-alloys 'me e ka aroloa ka mekhahlelo e mene:
1. Tšepe e tlaase ea carbon
Tšepe e bonolo e na le carbon content ea 0.04-0.3% 'me ke boemo bo tloaelehileng ka ho fetisisa ba carbon steel.Tšepe e bonolo e boetse e nkoa e le tšepe e bonolo kaha e hlalosoa e le ho ba le carbon content ea 0.05-0.25%.Tšepe e bonolo e na le ductile, e bonolo haholo 'me e ka sebelisoa likarolong tsa' mele oa koloi, lakane le lihlahisoa tsa terata.Qetellong e phahameng ea mefuta e tlaase ea carbon content, hammoho le ho fihla ho 1.5% manganese, thepa ea mochine e loketse litempe, li-forging, li-tubes tse se nang moeli le lipoleiti tsa boiler.
2. Tšepe ea carbon e bohareng
Litšepe tse mahareng tsa khabone li na le khabone ka har'a 0.31-0.6% le manganese ka har'a 0.6-1.65%.Tšepe ena e ka phekoloa mocheso le ho tima ho tsoela pele ho fetola microstructure le thepa ea mochine.Lisebelisoa tse tsebahalang li kenyelletsa li-axle, li-axles, likere, liporo le mabili a terene.
3. Tšepe e phahameng ea carbon
Tšepe e phahameng ea carbon e na le carbon content ea 0.6-1% le manganese ea 0.3-0.9%.Thepa ea tšepe e phahameng ea carbon e etsa hore e loketse ho sebelisoa e le liliba le terata e matla e phahameng.Lihlahisoa tsena li ke ke tsa kolobisoa ntle le haeba mokhoa o qaqileng oa phekolo ea mocheso o kenyelelitsoe ts'ebetsong ea welding.High carbon steel e sebelisoa bakeng sa lisebelisoa tsa ho seha, terata e matla e phahameng le liliba.
4. Tšepe ea carbon e phahameng ka ho fetisisa
Litšepe tsa khabone tse phahameng haholo li na le khabone ea 1.25-2% 'me li tsejoa e le li-alloys tsa liteko.Tempering e hlahisa tšepe e thata haholo, e leng molemo bakeng sa lisebelisoa tse kang lithipa, li-axle kapa litebele.
