1010 Steel Shim Stock, Full Hard Temper, ASTM A109, 0.003" Thick, 6" Width, 100" Length

The carbon steel 1010 shim stock roll has a full-hard temper for dimensional stability and is harder and compresses less than brass and aluminum during use. This material can be welded or brazed. The full-hard temper provides high hardness and yield strength ratings for dimensional stability during use. This roll has a Rockwell hardness rating of B90 and conforms to American Society for Testing and Materials (ASTM) A109 and Federal Specification (Fed. Spec.) QQ-S-698.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 costly replacement parts and lost production time. While most shim stock is sold in standard thicknesses of solid material, shim stock with laminated layers is composed of stacked foil sheets that have been pressed and heated together and that peel off to adjust the shim’s thickness to the application.
