Hardness of 4130 steel

Hardness is a qualitative, comparative parameter that describes the response of a material to local surface deformation. There are many hardness scales that depend on standard hardness testing machines; for most alloys, the Rockwell indenter machine is used and each material is graded on the Rockwell hardness scales. There are three main scales (A, B, & C), where the Rockwell B hardness scale value is depicted in Table 1. For reference, the Rockwell B hardness of copper, a relatively soft metal, is 51. Type 4130 steel has a Rockwell hardness of 92, which is high for steel and shows why this material is so tough. A high hardness usually indicates increased stiffness, which is an ideal property for materials in compression.

Elongation at break is a measure of a material's ability to resist plastic deformation before its fracture point. It is found by pulling a test specimen apart and measuring the ratio of its initial length to its final length before fracture. Elongation at break is generally used to show how bendable a material is,

and/or how it withstands plastic deformation. This parameter is quite high in 4130 steel (25.5%), which shows the great workability of this alloy steel.
