Carbon and Low-Alloy Steels
Carbon and Low-Alloy Steels Overview
Due to cost, strength, and versatility, carbon and low-alloy steels are widely used in casting. Carbon steel (0.0218-2.11% carbon) offers hardness and ductility varying by low, medium, and high carbon grades. Low-alloy steels have alloying elements such as chromium, nickel and molybdenum (usually less than 8%) which improve wear resistance, corrosion resistance and high temperature strength, and are therefore suitable for engineering structures, machinery and automotive parts.
Advantages of Carbon and Low-Alloy Steels
Excellent hardenability
Good weldability
Wide range of mechanical properties
Strong heat treatment response
Cost efficiency
