What is 4140 Steel Plate Hardness?
The 4140 steel plate is a popular alloy steel known for its relatively high hardness. The hardness of 4140 steel plate can vary depending on several factors, such as the heat treatment it has undergone. In its annealed state, the hardness is relatively low, which makes it easier to machine. However, when it is heat - treated, especially through processes like quenching and tempering, its hardness can be significantly increased.
Typically, in the quenched and tempered condition, the Brinell hardness (HB) of 4140 steel plate can range from around 250 to 320 HB. Rockwell hardness (HRC) values can be in the range of 25 - 35 HRC. This hardness gives it good wear resistance, making it suitable for applications where components need to withstand abrasion, such as in the manufacturing of gears, shafts, and tooling.
