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.
|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.|
