What scale is used to measure the hardness of steel?
Rockwell hardness
What hardness should SAE 1010 cold rolled steel be?
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB. *(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)
When reading the steel heat treatment notation RC what does the R mean?
RC stands for Rockwell Hardness C scale; the different letters A,B,C etc. are based on different loads and indenters for measurement. C scale is typical for steels, while B scale is typical for aluminum. There are conversion tables for these if needed.
What is the Rockwell hardness of 420 stainless steel?
chrome vanadium steel is designated C41-55.
What is the Hardness of 1018 carbon steel?
Between 121-137 on the Brinell hardness scale - which is quite soft. The end parts are generally case-hardened before use to 60+ Rockwell "C".

What is the hardness of 55 -58 HRC mean?
Hardness of metal is determined by the carbon content. HRC is the Rockwell Hardness Scale. A hardness of 55-58 is not very hard compared to carbon steel.

What is the Hardness Rockwell C scale?
This is a method used to determine the hardness of a metal. If you know the type of metal and the hardness, this will tell you the Tensile Strength of the metal and how well it was heat treated. The method uses a ball or a pin to strick the metal and leave a small indention. The size and depth that the ball makes in the metal is inversely proportional to the hardness. Using the scale, you can then determine if the part has completed the proper heat treatment as required by the Engineering drawing. There are 3 Rockwell scales: A, B, C. Rockwell C scale is for the hardest of metals such as steel. Rockwell B is for metal such as soft aluminum and A is for even softer metals.
