Carbon and Low Alloy

These alloy steel grades are used for their strength and hardness that is obtained through chemistry and heat treatment. They provide no corrosion resistance; however, depending on strength levels can provide reasonable wear or erosion resistance.

Alloy Properties
Representative Alloys	8620, 4130, WCB, LC3, C5
Applications	Machine parts, structural components
Limitations	Low corrosion resistance.
Typical Uses	Knives, cutter blades, die casting dies
Machinability	Fair to good, depending on grade and condition
Weldability	Fair to excellent, depending on grade and condition.
