Shaw hardness test requirements for channel steel

　　Shaw hardness test requirements for channel steel

　　The Shore hardness test of channel steel shows that the punch component and drop height vary with the experimental machine. So, although the channel steel has a calculation formula, it still directly reads the values on the experimental machine.

　　The reading of its rebound height involves visually measuring the C-type experimental machine and the D-type experimental machine displayed on the dial according to the longitudinal scale of the channel steel. Also, due to errors in reading values, the rule takes the average of five consecutive readings as the Shore hardness value. Despite this, the values may still vary greatly depending on the experimental operators, and the channel steel requires proficiency in reading the values. So, there is a tendency to distrust Shaw hardness.

　　However, due to the use of the rebound principle of the hammer head, the channel steel does not harm the experimental target in this experiment. Therefore, it is possible to directly experiment with products and processed data. Moreover, the experimental equipment is simple and easy to move. Also, the measuring cylinder can be individually removed from the experimental equipment and held in hand for experimentation.

　　Due to its many advantages, it is widely used on site. Shaw hardness is indicated by Hs, and it is necessary to distinguish between the visual (C-type) and target (D-type) testing machines for channel steel by HsC and HsD. Shaw hardness is not only numerically unstable, but its experimental methods are also completely different. So, even with the same hardness, its properties are completely different. So, it is still difficult to understand the Shaw hardness of channel steel.
