301 stainless steel strip is a common stainless steel material, and its hardness is usually evaluated through the Rockwell hardness test. The following is a brief introduction to the hardness standards and testing methods of 301 stainless steel strips:
Hardness standard:
Rockwell hardness: Rockwell hardness test is one of the most commonly used hardness testing methods and is suitable for various metal materials, including stainless steel. The hardness of 301 stainless steel strip is usually expressed by Rockwell hardness value, such as HRC (Rockwell hardness C) or HRB (Rockwell hardness B), etc.
Test Methods:
Preparation work: Before performing the Rockwell hardness test, it is necessary to ensure that the test instrument is calibrated normally and the sample surface is cleaned and smoothed.
Testing process:
Place the 301 stainless steel strip sample on the hardness testing machine and ensure that the sample is in good contact with the test head.
Select the appropriate Rockwell hardness test scale and load, and usually select the appropriate test parameters according to the hardness range of stainless steel.
Under a set load, the test head applies pressure to the specimen and measures the depth of penetration into the surface of the specimen.
After the load is released, the hardness value is calculated from the depth and diameter of the indentation.
Record the results: After the test is completed, record the Rockwell hardness value of the 301 stainless steel strip and perform multiple tests as needed to ensure accuracy.
Interpretation of the results: Based on the obtained Rockwell hardness value, the hardness level of the 301 stainless steel strip can be judged, and then its applicability and performance characteristics can be evaluated.
