About 1095 Steel Shim Stock, Blue
The spring steel 1095 shim stock roll has been blue tempered for the best dimensional stability of all tempers and provides high wear resistance and strength due to the material’s high carbon content. The material has been blue tempered, which strengthens the material to the highest hardness and yield strength ratings possible for rigidity during use. The material has a blue finish. This roll has a Rockwell hardness rating of C48 to C51 and conforms to SAE Aerospace Materials Standards (AMS) 5122 and United States Military Standard (MIL SPEC) S-7947. Shim stock is fabricated by cold rolling, which is the process of reducing a material’s thickness by passing it between two rollers. Cold rolling can cause a temper to form in the material, increasing the yield strength (the amount of force necessary to permanently bend or deform the material) as well as hardness ratings of the material. The higher its hardness and yield strength ratings, the more likely the shim is to preserve its thickness and shape over time while in use, but the harder it will be to bend and shape. Quarter-hard tempered material provides the lowest hardness and yield strength ratings and the greatest ductility of the tempers, with half-hard, three-quarters-hard, full-hard, spring, and blue tempered material respectively increasing in hardness and yield strength. Annealed shim stock has been heated and cooled to remove any temper and reinstate the material’s natural formability (ability to be bent) after it has been cold rolled. Shim stock, which is sold in either sheets or rolls, is a very thin material that can be cut, sawed, stamped, milled, or bored into specific shapes. These fabricated pieces, also called shims, can be placed between objects for a variety of uses, including added support, improved leveling, increased insulation, tighter sealing, and better spacing. Shims can also be used to fill in gaps between machine parts that are prone to wear, avoiding
