Shim Steel

In engineering, a shim is a thin piece of material, used to fill small gaps or spaces between objects. Shims are typically used in order to support, adjust for better fit, or provide a level surface. Shims may also be used as spacers to fill gaps between parts subject to wear. Hardened spring steel is very suitable for …

CS80

CS80 is usually supplied in the ready hardened or hardened and tempered condition, with a grey, blue or polished finish. The advantage of hardened and tempered steel is that it can be used to produce components that do not require the cost of further hardening. It is the most common of the carbon grades to …
