Tlhaloso ea Tšepe ea Carbon le Alloy Steel

 

Tšepe, joalo ka ha bohle re tseba, ke lentsoe le akaretsang bakeng sa li-alloys tsa tšepe-carbon. Carbon steel (e khutsufalitsoeng joalo ka tšepe ea khabone) ke motsoako oa tšepe oa khabone o nang le khabone e ka tlase ho 2.11%. Motsoakong oa eona oa lik'hemik'hale, ho phaella ho tšepe le k'habone, ho boetse ho na le litšila tse fokolang tse kang silicon, manganese, phosphorus, le sebabole, 'me ho ke ke ha e-ba le likarolo tse ling tsa motsoako.

 

Lihlahisoa tsa carbon steel li etsa hoo e ka bang 80% ea lihlahisoa tsohle tsa tšepe, 'me li sebelisoa haholo kahong, marokho, likoloi, likepe, ho etsa mechine, indasteri, petrochemicals, nts'etsopele ea leoatle le masimo a mang.

 

Alloy steel ke tšepe e nang le motsoako o le mong kapa ho feta tse ling tse kentsoeng ho tšepe ea carbon, joalo ka chromium, nickel, tungsten, titanium, vanadium, manganese, koporo, aluminium, molybdenum, joalo-joalo, molemong oa ho eketsa thepa e itseng ea tšepe. Likarolo tsena tsa lik'hemik'hale li eketsoa ka likarolo tse fapaneng / ho kopanya ho fana ka litlamorao tse fapaneng, joalo ka boima bo ntseng bo eketseha, ho ntlafatsa ho hanyetsa ha kutu, ho matlafatsa matla, ho ntlafatsa sebopeho, ho fetola weldability, jj.

 

Tlhahiso ea tšepe ea alloy e etsa hoo e ka bang 20% ​​ea kakaretso ea tšepe 'me e sebelisoa haholo likarolong tse fapaneng tse kang ho etsa mechine, petrochemicals, kaho, lik'hemik'hale tsa letsatsi le letsatsi, lisebelisoa tsa bongaka, likhoele tsa maiketsetso, lipalangoang, joalo-joalo.

 

 

Classification of Carbon Steel le Alloy Steel

• Sehlopha sa carbon steel

Ho ea ka carbon content, e ka aroloa ka: low carbon steel, medium carbon steel, high carbon steel; ha carbon content e phahame, ho ba le boima bo phahameng le ho theola boima bo tlaase.

 

Tšepe ea khabone e tlase: litaba tsa khabone C%≤0.25%. Litšepe tse tloaelehileng tsa khabone tse tlase tse sebelisoang ho etsa li-fasteners li kenyelletsa tšepe ea A3, tšepe ea Q215A, tšepe ea Q235, tšepe ea 20#, tšepe ea 22#, joalo-joalo.

Medium carbon steel: carbon content 0.25%＜C%≤0.45%. Litšepe tse tloaelehileng tsa khabone tse sebelisoang ho etsa li-fasteners li kenyelletsa 35# tšepe, 45# tšepe, jj.

High carbon steel: carbon content C% ~0.45%, high carbon steel ha e le hantle ha e sebelisoe ho etsa fasteners 'marakeng, ka lebaka la lik'habone tse phahameng, lintho tse thata le tse brittle, tse bonolo ho robeha.

 

• Sehlopha sa tšepe ea alloy

Ho ea ka kakaretso ea likarolo tsa alloy, e arotsoe ka: tšepe e tlaase ea alloy, tšepe e bohareng ea alloy, tšepe e phahameng ea alloy, e nang le likarolo tse fapaneng tsa motsoako le sebopeho, le ts'ebetso e fapaneng.

 

Tšepe ea alloy e tlaase: kakaretso ea alloy content ≤5%;

Tšepe ea alloy e mahareng: 5%＜kahare ea alloy content ≤10%

Tšepe e phahameng ea alloy: litaba tsa alloy ~ 10%.

 

Lisebelisoa tse tloaelehileng tsa alloy tse sebelisetsoang ho etsa li-fasteners li kenyelletsa: 30CrMo, 40Cr, 35CrMo, 42CrMo, joalo-joalo.

 

Litšobotsi tsa Tšepe ea Carbon le Alloy Steel

• Litšobotsi tsa tšepe ea carbon

Ts'ebetso ea tšepe ea carbon e itšetlehile ka boleng ba eona ba carbon. Ha carbon content e phahame, matla le ho tiea li phahame, 'me ho theola polasetiki, ho tiea le ho cheseha.

 

Melemo: polasetiki e ntle le weldability; theko e tlaase, e bonolo ho fofonela; theknoloji e sebetsang hantle; tshebetso e ka ntlafatsoa ka ho fetola carbon content kapa ho fetola mokhoa oa ho sebetsa;

 

Go tlhoka mesola: matla a fokolang hanyane; boima bo fokolang; ho se lekane ho hanyetsa mocheso o tlase; khanyetso e tlase ea kutu; conductivity e tlaase ea makenete; ho bonolo ho ba le makenete sebakeng sa makenete.

 

• Litšobotsi tsa tšepe ea alloy

Lintho tse fapaneng tsa alloy tse kentsoeng li na le thepa e fapaneng.

 

Melemo: tshebetso e ntle e akaretsang; e fumanehang bakeng sa merero e khethehileng; matla a phahameng le boima bo phahameng; ho thatafala ha bonolo, ha ho bonolo ho holofala le ho petsoha; ho hanyetsa ho roala, ho hanyetsa kutu, ho hanyetsa mocheso o tlase, ho hanyetsa mocheso o phahameng, ho se na matla a makenete, joalo-joalo;

 

Mefokolo: theko e boima; ho rarahane ho feta ho bōpa le mekhoa ea phekolo ea mocheso.

 

Tšebeliso ea tšepe ea Carbon le Alloy Steel

• Tšebeliso ea tšepe ea carbon

 

Hangata tšepe ea carbon e sebelisoa ho etsa likarolo tse fapaneng tsa moaho, lijana, mabokose, 'mele oa sebōpi le mechini ea temo, likaroloana tse nyane tse jarang moroalo, li-washer, likhoele tsa cotter, lithupa, litempe le likarolo tse cheselitsoeng, jj.

 

Litšepe tsa carbon tse sebelisetsoang ho etsa li-fasteners

 

Q215A tšepe e loketse ho etsa li-washer;

 

Q235 tšepe e loketse ho etsa liboutu, linate, li-screw sleeves, cotter pins, rivets, joalo-joalo, 'me e sebelisoa haholo bakeng sa lihlahisoa tse se nang litlhoko tse thata tse kang liboutu tsa 4.8-grade, 4-grade nuts le li-screws tse nyenyane;

 

35# tšepe le 45# tšepe ke tsa meaho ea tšepe ea boleng bo holimo, 'me hangata e sebelisoa ho etsa liboutu tsa grade 8.8, linate tsa grade 8 le li-fasteners tsa grade 8.8.

 

• Tšebeliso ea tšepe ea alloy

 

Tšepe ea alloy e ka sebelisoa ho etsa likarolo tsa makoloi a lipalangoang joalo ka likoloi, likepe le lifofane; likarolo tsa lisebelisoa tsa mochini, lirokete, limisaele, joalo-joalo; le ho etsa li-bearings tse fapaneng, lisebelisoa tsa ho itšeha, lisebelisoa tsa ho lekanya, liliba, hlobo e chesang le e batang, hlobo e bilikang, liliba, lisebelisoa, joalo-joalo.

 

E sebelisoa liketsahalong tse khethehileng, tikolohong e thibelang mocheso le ho bola, joalo ka li-turbine tsa mouoane, li-boilers, lisebelisoa tsa lik'hemik'hale, joalo-joalo.

 

Tšepe ea alloy e sebelisetsoang ho etsa li-fasteners

 

Haholo-holo e sebelisetsoang ho hlahisa li-bolts le linate tse matla, tse kang lisebelisoa tsa grade 10.9 li kenyelletsa 30CrMo le 40Cr; Lisebelisoa tsa sehlopha sa 12.9 li kenyelletsa: 35CrMo, 42CrMo, joalo-joalo.

 

30CrMo e atisa ho sebelisoa ho etsa liboutu le li-studs tlas'a meroalo e phahameng; li-fasteners tse fapaneng tse sebelisoang mocheso o phahameng (ka tlase ho 450 ℃) libakeng tse kang li-turbine tsa mouoane le li-boilers; flanges le linate tse sebelisoang mocheso o phahameng (ka tlase ho 500 ℃) maemo a khatello;

 

40Cr e loketse ho etsa li-sleeve tsa screw, lithakhisa, li-screws tsa molamu tse hokelang, linate, joalo-joalo;

 

35CrMo e atisa ho sebelisoa ho etsa li-fasteners tse fapaneng tlas'a meroalo e phahameng, joalo ka li-fasteners bakeng sa lijenereithara tsa turbine ea mouoane; li-fasteners tse fapaneng tse sebelisoang mocheso o phahameng (ka tlase ho 480 ℃) libakeng tse kang li-boilers;

 

42CrMo e loketse ho etsa li-fasteners tse hlokang matla a phahameng ho feta 35CrMo.

 

Ha ho nahanoa ka litšobotsi tsa tšepe ea carbon le alloy alloy, ha u khetha thepa ea fastener, tšepe ea carbon e ka fuoa pele molemong oa ho finyella litlhoko tsa tšebeliso; haeba litlhaloso li le khōlō, sebōpeho se rarahane haholoanyane, 'me litlhoko tsa matla le tse nepahetseng li phahame, kapa ho na le litlhoko tsa boima bo chesang le litšoantšiso tse ling tse khethehileng, joale tšepe ea alloy e lokela ho sebelisoa.

 

Ka mor'a ho bala see, na u ka khetholla pakeng tsa tšepe ea carbon le alloy steel?
