Iimbonakalo:
1.Ityhubhu yentsimbi yekhabhoni ephantsiengenamthungoyintsimbi yekhabhoni enomxholo wekhabhoni ongaphantsi kwe-0.25%.Ikwabizwa ngokuba yintsimbi ethambileyo ngenxa yamandla ayo aphantsi, ubulukhuni obuphantsi kunye nokuthamba.
2. Ukwakhiwa kwe-annealed of low carbon steel tubing kunye ne-seamless i-ferrite kunye nenani elincinci le-pearlite, elinamandla aphantsi kunye nobunzima, kunye neplastiki enhle kunye nokuqina.
3. I-carbon steel tubing ephantsi ene-seamless inokwakheka kakuhle okubandayo kwaye ingabanda eyenziwe ngokugoba, ukugoba, ukunyathela, njl.
4. I-carbon steel tubing ephantsi ene-seamless ine-weldability efanelekileyo.Kulula ukwamkela ukucutshungulwa okuhlukahlukeneyo okufana nokubumba, ukuwelda kunye nokusika.

Unyango lobushushu:
I-carbon steel tubing ephantsi ene-seamless inomdla omkhulu wokuguga, kokubili ukucima kunye nokuguga, kunye nokuguquka kunye nokuguga.Xa intsimbi ipholile kwiqondo lokushisa eliphezulu, i-carbon kunye ne-nitrogen kwi-ferrite i-supersaturated, kunye nekhabhoni kunye ne-nitrogen kwintsimbi inokuqulunqwa ngokucothayo kwiqondo lokushisa eliqhelekileyo, ukwenzela ukuba amandla kunye nobulukhuni bentsimbi buphuculwe, kunye ne-ductility. nokuqina kuyathotywa.Le nto ibizwa ngokuba kukuphelisa ukuguga.I-carbon steel tubing ene-seamless iya kuba nefuthe lokuguga nangona ingacinywa.I-deformation ye-carbon steel tubing ephantsi kunye ne-seamless ivelisa inani elikhulu lokuchithwa.I-athomu yekhabhoni kunye ne-nitrogen kwi-ferrite idibanisa i-elastically kunye ne-dislocations, kunye ne-carbon kunye nee-athomu ze-nitrogen ziqokelelana malunga nemigca yokuchithwa.Le ndibaniselwano ye-athomu ye-carbon kunye ne-nitrogen kunye nemigca yokuchithwa ibizwa ngokuba yi-Cochrane gas mass (i-Kelly gas mass).Yandisa amandla kunye nobunzima bentsimbi kwaye iyanciphisa i-ductility kunye nokuqina.Le nto ibizwa ngokuba kukuguga deformation.Ukuguga kwe-Deformation kuyingozi ngakumbi kwi-ductility kunye nokuqina kwentsimbi ye-carbon ephantsi kunokucima ukuguga.Kukho amanqaku acacileyo aphezulu nasezantsi kwi-tensile curve ye-low carbon steel.Ukusuka kwinqanaba lesivuno esiphezulu kude kube sekupheleni kokwandiswa kwesivuno, ibhendi yokushwabana komphezulu eyenziwe kumphezulu wesampulu ngenxa yokuguqulwa okungalinganiyo ibizwa ngokuba yiRydes belt.Iindawo ezininzi zesitampu zidla ngokuchithwa.Kukho iindlela ezimbini zokuthintela.Indlela ephezulu ye-deformation yangaphambili, insimbi ekhubaziweyo ifakwe ixesha elithile kwaye ibhande leRudes liphinda liveliswe xa kugxilwa, ngoko ke intsimbi yangaphambili ayifanele ibekwe ixesha elide ngaphambi kokunyathela.Enye into yokongeza i-aluminium okanye i-titanium kwintsimbi ukwenza i-compound ezinzile kunye ne-nitrogen ukukhusela ukuguga kwe-deformation okubangelwa ukubunjwa kobunzima bomoya we-Kodak.
