High-Strength 1075 Spring Steel Strips

Create high-strength parts that compress and extend without losing shape, such as springs, shims, and clips. Also known as scaleless steel, this 1075 spring steel comes hardened for extra wear and fatigue resistance. However, you’ll need to cut it to shape since it’s too hard to form. For more complex shaping, consider annealed 1075 spring steel sheets, or 1050 for the tightest bends.

Shim Stock

Cut into custom shapes to create shims that suit your needs. With thickness tolerances as fine as a strand of hair, the shims will precisely align, space, and level components on dies, presses, and machinery.

You can stack multiple shims to achieve your exact thickness, but stacking more than four may cause them to shift. Remember, fewer shims are better, so a couple of thicker shims are more stable than a bunch of thin shims.

Stress-Resistant Spring Steel—Harder and holds its shape better than carbon steel. Use it for high-stress applications, such as leveling heavy machinery. It's best for dry areas since moisture will cause it to rust.

Temper Rating—Choose half hard to create shims that you’ll need to bend or shape. Opt for full hard to make stronger shims that will maintain their shape under loads.

High-Strength 1075 Spring Steel Sheets

Form high-strength springs, shims, and clips. 1075 spring steel is easier to shape than 1095 because it’s alloyed with less carbon. For more complex forming, consider 1050 spring steel instead. Once made into a part and heat treated, 1075 continues to hold its shape when compressed and extended, but not as well as 1095.
