* Whakamahia te CE ina nui ake te waro i te 0.12%, me te whakamahi i te CE IIW inaP cm te waro he iti iho i te rite ranei ki te 0.12%.

CEP cm = C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+5B

Mena he iti iho i te 0.0005% te hua o te tātari whakarewa o B, karekau he take ki te whakauru i te tātaritanga o te huānga B i roto i te tātaritanga hua, ka taea te whakaaro ko te ihirangi B hei kore i roto i te tatauranga CEP cm rite waro.
