Comprehensive Overview Of 4140 Steel Hardness - China
price: 999.00 Dollar US$
4140 steel is a medium-carbon low-alloy steel composed of chromium, molybdenum and carbon.
Its hardness is mainly determined by the carbon content.
4140 steel hardness tested under different conditions will also be different.
Through correct heat treatment and hardness testing methods, the hardness of 4140 steel suitable for different application needs can be obtained.
So understanding the 4140 steel hardness is critical to evaluating its application in projects.
This article will provide a comprehensive overview of the knowledge points about 4140 steel hardness.
4140 Steel Hardness Testing
1 - Brinell Hardness Test: It is one of the most commonly used hardness testing methods.
By applying a certain predetermined load on the surface of the steel, the diameter of the indentations of different depths formed is measured.
According to the indentation diameter and test Load calculation hardness value.
2 - Vickers Hardness Test: This method is a commonly used microhardness testing method represented by HV (Vickers hardness).
A Vickers hardness testing machine is used to apply a certain load of diamond or hard alloy indenter to the surface of 4140 steel, measure the diagonal length of the indentation, and calculate the hardness value.
3 - Rockwell Hardness Test: This method is a metal hardness test method represented by the HRC symbol, which measures the depth or union depth and rebound depth of the indentation formed on the surface of 4140 steel, and reads the hardness value based on the measurement.
4 - Ultrasonic Hardness Test: It is a non-contact hardness testing method that uses the propagation speed and reflection characteristics of ultrasonic waves on the surface of steel to infer hardness.
The hardness value is calculated by measuring the propagation time of ultrasonic waves in the material.
