Carbon and Low Alloy Steel Investment Castings

Carbon and Low Alloy Steel Investment Castings

Processed to obtain a wide range of properties, these alloys provide designers much freedom and are used within many industries and applications. Carbon and Low Alloy steels are commonly used for pressure containing and structural applications due to the increased strength, hardenability, toughness, and resistance to wear and abrasion. The relative lower cost also makes these alloys attractive for use where applicable.
