* Ibirimo bya Manganese birashobora kwiyongeraho 0,05% kuri buri 0.01% kugabanya ibirimo karubone, kugeza kuri 1.65%

Ibikoresho bya mashini bisabwa:

Imbaraga zitanga umusaruro: 60360Mpa

Imbaraga zingana: 60460Mpa

Imbaraga zingutu zicyuma gisudira: 60460Mpa

Kurambura: ≥1940 * AXC0.2 / 4600.9, aho AXC ni agace kambukiranya icyitegererezo cya tensile

Kwihanganira diameter yo hanze yumuyoboro wibyuma:

* Ibirimo bya Manganese birashobora kwiyongeraho 0,05% kuri buri 0.01% kugabanya ibirimo karubone, kugeza kuri 1.65%.

* Nta kongera nkana boron byemewe, bisigaye B≤0.001%

Carbone bihwanye:

CEP cm: ≤0.25

CEIIW: ≤0.43

* Koresha CE mugihe karubone irenze 0,12%, kandi ukoreshe CE IIW mugiheP cm ya karubone iri munsi cyangwa ingana na 0,12%.

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

Niba ibisubizo byo gusesengura gushonga kwa B biri munsi ya 0.0005%, ubwo rero nta mpamvu yo gushyira isesengura ryibintu B mu isesengura ryibicuruzwa, kandi ibirimo B bishobora gufatwa nka zeru muri karubone ihwanye na CEP cm.

CEIIW = C + Mn / 6 (C + Mo + V) / 5 + (Ni + Cu) / 15

Imbaraga zingana: 460-760Mpa

Ikigereranyo cy'umusaruro: ≤0.93 (ikoreshwa gusa kuri D> 323.9mm y'icyuma)

Imbaraga zingirakamaro zicyuma gisudira: 60460Mpa

Kurambura ntarengwa: = 1940 * AXC0.2 / 4600.9, aho AXC nigice cyambukiranya igice cyurugero rwa tensile.
