* Ibirungo bya Manganese birashobora kwiyongeraho 0,05% kuri buri 0.01% kugabanuka kwa karubone kugera kuri 1.35%.
** Ibirimo Niobium, bishingiye ku masezerano, birashobora kongerwa kugera kuri 0,05% yo gusesengura gushonga na 0.06% yo gusesengura ibicuruzwa byarangiye.
Ibisabwa byo kuvura ubushyuhe:
1. Kora hejuru ya 815 ° C.
2. Kora hejuru ya 815 ° C, hanyuma ushake.
3. Ubushyuhe bwakozwe hagati ya 845 na 945 ° C, hanyuma bukonjeshwa mu itanura hejuru ya 845 ° C (kubituba bidafite kashe gusa).
4. Imashini hanyuma ihindurwe nkuko byavuzwe haruguru Ingingo ya 3.
5. Gukomera hanyuma ugahinduka hejuru ya 815 ° C.

Ikizamini Ingaruka
Ubushyuhe bw'ikizamini: -45 ° C.
Iyo ingero ntoya ya Charpy ingero zikoreshwa kandi ubugari bwikigereranyo kiri munsi ya 80% yubugari nyabwo bwibikoresho, ubushyuhe buke bwikigereranyo bugomba gukoreshwa nkuko bibarwa mu mbonerahamwe ya 6 yerekana ASTM A333.

Uburebure bwurukuta rwihanganira imiyoboro yicyuma:
Ingingo iyo ari yo yose ntishobora kuba munsi ya 12.5% yuburebure bwurukuta.Niba uburebure bwurukuta ntarengwa buteganijwe, nta ngingo igomba kuba munsi yuburebure bwurukuta rusabwa.
