Steel Hardness Converter
The Steel Hardness Converter allows you to instantly convert steel hardness values between Rockwell (HRC), Brinell (HB), and Vickers (HV) scales. You can quickly correlate hardness to approximate tensile strength, making it easier to compare materials, check specifications, and support quality control in machining and heat-treatment operations.
Brinell HB
Vickers
Rockwell C
Rockwell B
Tensile Strength
Please note: If the numbers you enter fall outside the valid range for a given scale, the result boxes will remain blank.
To achieve the hardness values you see in this converter, tool and engineering steels usually require controlled heat treatment. The chosen process and hardness level affect wear resistance, abrasion performance, and impact toughness for each grade.
If you need steels supplied to a specific hardness range with full test certification, refer to our tool steel and alloy steel product pages, where you can download detailed specification data sheets for our most popular grades.
