SUSPENSION CAST DISPERSION-HARDENING FERRITE-CARBIDE DIE STEEL

摘要

FIELD: metallurgy.;SUBSTANCE: proposed composition contains the following substances, in wt %: carbon 0.27 - 0.32, titanium 5.8 - 6.2, nickel 0.5 - 0.9, titanium carbide (TiC) 0.5 -1.5, iron making the rest. Besides, it may contain up to 0.05% traces of manganese, 0.15 - 0.17% of silicon, and ≈0.03% of sulfur and phosphorus. Titanium carbide is added in the form of powder with particle size of up to 10 mcm into ladle or in melt jet in teeming steel into metallic chill mould.;EFFECT: improved processing and operating properties, lower costs.;2 tbl
