Izidingo zezakhiwo zemishini:
Amandla okukhiqiza: ≥360Mpa
Amandla okudonsa: ≥460Mpa
Amandla okunamathela kwepayipi lensimbi elihlanganisiwe: ≥460Mpa
Ukwelulwa: ≥1940* AXC0.2/4600.9, lapho i-AXC iyindawo enqamula isampula yokuthamba
Ukubekezelela ububanzi bangaphandle bepayipi lensimbi:

Insimbi ibanga: L360N or X52N(PSL2)
Amakhemikhali ukwakheka izidingo:
C: ≤0.24
I-Si: ≤0.45
Mn: ≤1.40
P: ≤0.025
S: ≤0.015
V: ≤0.10
Inombolo:≤0.05
Isilinganiso: ≤0.04
I-Cu: ≤0.50
I-Ni: ≤0.30
I-Cr: ≤0.30
UMsombuluko: ≤0.15
I-V+Nb+Ti: ≤0.15
* Okuqukethwe kwe-Manganese kungandiswa ngo-0.05% kukho konke ukwehla kwe-carbon okungu-0.01%, kuze kufike ku-1.65%.
* Akukho ukungezwa kwe-boron ngamabomu okuvunyelwe, okusele okungu-B≤0.001%
Ikhabhoni okulinganayo:
I-CEP cm: ≤0.25
I-CEIIW: ≤0.43
* Sebenzisa i-CE uma okuqukethwe kwekhabhoni kungaphezu kuka-0.12%, bese usebenzisa i-CE IIW uma i-P cm okuqukethwe kwekhabhoni kungaphansi noma kulingana no-0.12%.
CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B
Uma umphumela wokuhlaziywa kokuncibilikisa kwe-B ungaphansi kuka-0.0005%, khona-ke asikho isidingo sokufaka ukuhlaziywa kwesakhi B ekuhlaziyweni komkhiqizo, futhi okuqukethwe kwe-B kungaphathwa njengo-zero ekubalweni kwe-CEP cm okulingana nekhabhoni.
CEIIW =C+Mn/6 (C+Mo+V)/5+(Ni+Cu)/ 15
Okwemishini izakhiwo izidingo:
Amandla okukhiqiza: 360-530Mpa
Amandla okudonsa: 460-760Mpa
Isilinganiso sesivuno: ≤0.93 (kusebenza kuphela kupayipi lensimbi elingu-D > 323.9mm)
Amandla okunamathela kwepayipi lensimbi elihlanganisiwe: ≥460Mpa
Ukwelulwa okuncane: = 1940* AXC0.2/4600.9 , lapho i-AXC iyindawo enqamula isampula yokuthambekela.
