* Ka taea te whakanui ake i nga tuhinga Manganese i te 0.05% mo ia 0.01% te whakaheke i nga ihirangi waro, tae atu ki te 1.65%.
* Kaore e whakaaetia te taapiri o te Boron, toenga B≤0.001%
Waro rite:
CEP CM: ≤0.25
CEIIW: ≤0.43
* Whakamahia te CE i te mea he nui ake te ihirangi waro i te 0.12%, a ka whakamahi i te CE IIW ka iti iho te ihirangi waro ki te 0.12%.
CEP CM = C + SI / 30 + MN / 20 + Cu / 20 + NI / 60 + cr / 20 + 5B
Mena he iti ake te hua o te tātaritanga pupuhi o te 0.0005%, na reira kaore he take hei whakauru i te tātaritanga B i roto i te tātaritanga hua, ka taea te rongoa i nga tuhinga b ki te tatauranga CM CM e rite ana ki te tātai CM CM E ōrite ana te CM CM CM E ōrite ana ki te tātai CM CM.
Ceiiw = C + MN / 6 (C + Mo + V) / 5 + (NI + CU) / 15
