Strip steel for shock absorber shims

Hardened and tempered precision strip steel for the manufacturing of high-performance shock absorber shims. Sandvik's shock absorber steel is available in carbon steel and stainless steel, providing more design freedom if the environment and fatigue conditions become extreme.

Close tolerances enables finetuning of shock absorber performance

Sandvik's shock absorber steel is characterized by close dimensional tolerances facilitating better control of the oil flow and the damping curve in the shock absorber. The improved possibility to finetune the oil flow is one of the most important factors in tailor-making safety and comfort.

Materials

The table describes Sandvik's two standard grades of shock absorber steel. Other grades can be offered on request.

Sandvik grade Description
Sandvik 20C A carbon steel of ASTM 1095 type with 1% carbon, characterized by high fatigue strength.
Sandvik 7C27Mo2 A martensitic chromium steel alloyed with molybdenum, giving better corrosion resistance and higher corrosion fatigue strength than conventional steels of the ASTM 420 type.

Width

Strip in standard thicknesses is stocked in widths up to 340 mm (13.39 in.), ready for slitting to the required width.

Finishes

Edges

Edges are slit and deburred. Shaved edges can be supplied on request.

Flatness

Maximum out-of-flatness across and along the strip is 0.30% of the nominal strip width.

Surfaces

Material is delivered bright, fine-polished. Read more about shock absorber steel surfaces.

Delivery forms and marking

Sandvik's strip steel for shock absorber shims is delivered in labelled coils packed in wooden cases. Each coil is marked with steel grade, heat, lot and coil number and nominal size, allowing full material traceability. Net and gross weights are marked on the case. For overseas shipment, coils are wrapped in paper and sealed in a plastic bag containing silica gel.

Material is protected against rust with oil.
