* Okuqukethwe kweManganese kungakhushulwa ngo-0,05% kuzo zonke ukuncishiswa okungu-0.01% kokuqukethwe kwekhabhoni, kufinyelela ku-1.65%.
* Akukho ukwengezwa kwe-BORON okuvunyelwe, okusalayo B≤0.001%
Ikhabhoni -lingene:
I-CEP CM: ≤0.25
Ceiiw: ≤0.43
* Sebenzisa i-CE lapho okuqukethwe kwekhabhoni kukhulu kune-0.12%, futhi kusetshenziswe i-CE IIW Upp cm okuqukethwe kwekhabhoni kungaphansi noma kulingana no-0.12%.
CEP CM = C + SIM / I-30 + MN / 20 + CU / I-FT + CR / 20 + v / 10 + v / 10 + 5b
Uma umphumela wokuhlaziywa kwe-smelting of b ungaphansi kuka-0.0005%, khona-ke asikho isidingo sokufaka ukuhlaziywa kwento b ekuhlaziyeni komkhiqizo, ukubalwa kwe-carbon elifanayo le-Carbon Cm.
Ceiiw = c + mN / 6 (C + mo + v) / 5 + (ni + cu) / 15
-Omshini izakhiwo Izidingo:
Ukukhiqiza amandla: 360-530MPA
Amandla we-Tensile: 460-700MPA
Isilinganiso se-Revel: ≤0.93 (kusebenza kuphela ku-D> 323.9mm ipayipi lensimbi)
Amandla we-Weld Tensile we-Welded Steel Pipe: ≥460MPA
Ubuncane be-Elongation: = 1940 * AXC0.2 / 4600.9, lapho i-AxC iyindawo yesigaba sesigaba sesampula eliseduze.
