Steel Hardness Conversion Table. This table shows approximate hardness of steel using Brinell, Rockwell B and C and Vickers scales. These conversion charts are provided for guidance only as each scales uses different methods of measuring hardness. The right hand column show an approximate equivalent tensile strength.
Hardness conversion table - Tensile strength, Vickers, Brinell och Rockwell (According to DIN 50150) The information below is for guidance only and should not be seen as fixed reference values. Some conditions, especially the incidence of cold work, can change the relationship between the tensile strength and hardness profoundly.

Alcobra Metals specializes in cut-to-length materials. You buy only what you need. There are no minimum orders.
431 is a high chromium-low nickel high hardenability Martensitic stainless steel with high strength and good corrosion resistance, as generally supplied hardened and tempered in the tensile range 850 - 1000 Mpa (condition T) Brinell range 248 - 302.Characterised by very good corrosion resistance in general atmospheric corrosive environments, good resistance to mild marine and industrial buy 430 rockwell hardness
Stainless steels are called as high-alloy steels. Due to the presence of large amounts of chromium in the range of 4 to 30%, they have high corrosion resistance than other steels. Stainless steels are classified into martensitic, ferritic and austenitic based on their crystalline structure. However buy 430 rockwell hardness
The Rockwell test of hardness HRc refers to the Rockwell Scale of Hardness, part C. The Rockwell scale is widely used by metallurgists to define just how hard a piece of steel is: the higher the number, the harder the steel. A particular metal's rating is important to the knife maker because a harder steel will hold an edge better than a softer buy 430 rockwell hardness
Hardness Conversion Chart - provides values for Brinell, Rockwell A, Rockwell B, Rockwell C, Rockwell D, Rockwell E, Rockwell F, Rockwell Superficial 15-N, Rockwell Superficial 30-N, Rockwell Superficial 45-N, Rockwell Superficial 30-T, Vickers 136, Shore, and tensile strength psi hardness
There are a large number of hardness testing methods available ( Vickers, Brinell, Rockwell, Meyer and Leeb).Although it is impossible in many cases to give an exact conversion, it is possible to give an approximate material-specific comparison table for steels.
Rockwell Hardness Testing Conditions. As the method is extended from metals to plastics, one has to be careful to consider: The effects of temperature: Small changes in temperature can result in first and second order phase transitions which can radically alter the hardness of the material.
