Steel Castings

2024-09-13
Steel castings are solid metal objects produced by filling the void within a mold with liquid steel. While cast steel typically has lower mechanical properties than other metals with the same chemical composition, they are better because they can be made into complex shapes in few steps.

Carbon Cast Steel
Like other types of steel, carbon cast steel is classified according to its carbon content. Low carbon cast steel is relatively soft and not readily heat-treatable, while medium carbon cast steel is somewhat harder and can be strengthened by heat treatment;high carbon cast steel is used when maximum hardness and wear resistance are desired.

Alloyed Cast Steel

Alloyed cast steel is categorized as either low- or high-alloy. Low-alloy cast steel reacts similarly to that of normal carbon steel. However, low alloy carbon steel has higher hardenability. High-alloy cast steel is designed to produce a specific property, such as corrosion resistance, heat resistance, or wear resistance.
