Hardness and Temper
Hardness and temper define the steel shim stock’s resistance to deformation and wear. Hardness is typically measured using Rockwell or Vickers hardness scales, while temper refers to the heat treatment process used to achieve the desired hardness and ductility. Harder shims are more resistant to indentation and abrasion, making them suitable for applications involving high loads or abrasive environments. However, excessively hard shims can be brittle and prone to cracking under stress. The temper, on the other hand, influences the shim’s ductility and ability to conform to irregular surfaces without fracturing.
Experimental data illustrates the relationship between hardness, temper, and performance. A comparative analysis of shim stock with Rockwell hardness values of C45, C50, and C55 revealed that the C55 hardness exhibited superior wear resistance in sliding friction tests, showing a 15% reduction in material loss compared to C45. However, bend tests revealed that the C55 hardness shim stock was more susceptible to cracking at higher bending angles. Tempering processes, such as annealing, can increase the ductility of high-hardness shim stock, improving its ability to conform to mating surfaces. Selecting the appropriate hardness and temper is a delicate balance, requiring consideration of both wear resistance and formability to ensure the best steel shim stock performance in the intended application.
Surface Finish and Flatness
The surface finish and flatness of the steel shim stock influence its contact area, friction characteristics, and ability to provide uniform support. A smooth surface finish minimizes friction and wear, particularly in sliding applications. Flatness refers to the degree to which the shim stock deviates from a perfectly flat plane. Deviations from flatness can lead to uneven load distribution, stress concentrations, and reduced accuracy in adjustments. Polished or ground surface finishes offer superior smoothness and flatness compared to mill finishes.
Quantitative data underscores the importance of surface finish and flatness. Tribological studies have shown that reducing the surface roughness of shim stock from 20 micro-inches Ra to 5 micro-inches Ra can decrease the coefficient of friction by as much as 30%. This reduction in friction can significantly extend the lifespan of mating components in sliding applications. Moreover, finite element analysis simulations have demonstrated that deviations from flatness exceeding 0.002 inches can result in stress concentrations exceeding the material’s yield strength in high-load applications, leading to premature failure. Therefore, applications requiring low friction, uniform load distribution, or high precision necessitate careful consideration of surface finish and flatness when selecting the best steel shim stock.
