the chemical compositions of new cast alloy steel with high si content was designed, its microstructure and corrosion behavior were studied.
设计了一种含硅量较高的新型铸造合金钢,并研究了该合金钢的显微组织及其腐蚀行为。
the cast alloy steel bit-sharpener has been prepared by pouring the chrome abrasion resistance steel and the low-alloy steel with fine impact resistance one-step using cast-in technique.
