Products Description
The hardness testing methods for high-strength shipbuilding steel plates mainly include the following: Rockwell hardness test.
Testing principle:
Use a conical diamond indenter or a steel ball indenter. First apply an initial test force, then apply a main test force, and then remove the main test force and measure the depth of the residual indentation.
Calculate the Rockwell hardness value according to the depth of the residual indentation. Different combinations of indenters and test forces correspond to different Rockwell hardness scales, such as HRC, HRB, etc.
Dimensional Deviation
| Nominal Thickness(mm) | Thickness Deviation per Given Width (mm) | |||
| ≤1200 | >1200~1500 | >1500~1800 | >1800 | |
| >6.0~8.0 | ±0.29 | ±0.30 | ±0.31 | ±0.35 |
| >8.0~10.0 | ±0.32 | ±0.33 | ±0.34 | ±0.35 |
| >10.0~12.0 | ±0.35 | ±0.36 | ±0.37 | ±0.43 |
Scope of application:
Suitable for high-strength shipbuilding steel plates in various hardness ranges. Different scales can meet the testing needs of materials with different hardnesses.
The testing speed is fast and it is suitable for rapid detection on the production site.
Advantages:
The testing operation is simple and fast, and the hardness value can be read directly.
It can test the hardness of thinner samples and surface hardened layers.
Disadvantages:
The hardness values between different scales are not directly comparable.
For uneven materials, the test results may not be accurate enough.
