Enwere ike kee ya ikuku ike na ngalaba atọ: ferrite otu bead na-enwu ọkụ na-agbasi ike na ike ikuku steel, ebe ike ikuku.
A. Njirimara mejupụtara nke na-ekpo ọkụ na-ekpo ọkụ bụ: carbon dị ala, wc<0.2%; Cr and Si improve the oxidation resistance of steel; Cr, Mo (W) are soluble in ferrite and enhance the recrystallization temperature, thus increasing the creep limit of the matrix; Cr, Mo, V (Ti) strengthen the dispersion.
Njirimara okpomoku: ihe eji eme oku (950 ~ 1050) ma tinye ya na ogo 100 (m. E {450 ogo). Anụ ahụ nkịtị bụ nri +, na ihe na-esote okpomọkụ dị elu iji bulie ndọtị ahụ (n'ihi ọkọchị carbon) iji melite nguzogide.
