* Zolemba za manganese zimatha kuwonjezeka ndi 0,05% pa kuchepetsedwa kwa 0,01% mu kaboni, mpaka 1.65%.
* Palibe chowonjezera champhamvu cha Boron chimaloledwa, otsalira b9.001%
Kaboni pepa chimozi modzi:
Cm cm: ≤0.25
Ceiiw: ≤0.43
* Gwiritsani ntchito CE CE pomwe zokhudzana ndi kaboni ndizoposa 0,12%, ndi kugwiritsa ntchito CE CM CM CRACB CM yomwe ili kapena yofanana ndi 0.12%.
CM CM = C + SI / 30 + MN / 20 + NI / 60 + 5 + 5H + 5B
Ngati zotsatira za kusanthula kwa b ndizosakwana 0.0005%, ndiye kuti palibe chifukwa chophatikizira kusanthula kwa chinthu chopanga, ndipo mawu a B amatha kuthandizidwa ngati zero wofanana wa cm.
Ceiiw = Cn / 6 (C + MO + V) / 5 + (Ni + Cu) / 15
Zazitsulo katundu ZOFUNIKIRA:
ZOTHANDIZA: 360-530MPA
Mphamvu yayikulu: 460-7600MPA
Gwiritsani ntchito: ≤0.93 (kungogwira ntchito d> 323.9mm chitsulo)
Woyenda bwino kwambiri wa chitoliro chachitsulo: ≥400MA
Kuchepera Kokulukiza: = 1940 * Axc0.2 / 4600.9, komwe Axc ndi gawo lokhalamo.
