Polished Multipurpose 304 Stainless Steel
Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The sheets, strips, bars, and adhesive-back foil are covered with a protective peel-off film. 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.
Brushed #3 finish has grain lines running in one direction to mask fingerprints. Mirror-like #8 finish is reflective and free of grain lines.
Foil, sheets, and strips are polished on one side.

- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C64
- Specifications Met: ASTM A684
These sheets have a softened temper, which is also known as annealed, so they can be easily formed into shape and then heat treated for spring properties. 1075 spring steel is easier to bend than 1095, but it has less bounce-back after heat treating. It is often used for springs and shims.

Easy-To-Form Multipurpose 1050 Spring Steel Sheets
- Yield Strength: 60,000 psi
- Hardness: Rockwell B92
- Heat Treatable: Yes
- Maximum Hardness After Heat Treatment: Rockwell C58
- Specifications Met: ASTM A682
Containing more carbon than low-carbon steel—but less than 1095 spring steel—1050 spring steel is easily formed into parts such as washers, brackets, and springs before being hardened for use. It resists stress, so it won’t snap when formed or twisted. Because it has a lower carbon content than 1095 spring steel, it’s not as wear resistant.

Extra-Corrosion-Resistant C-276 Nickel Sheets and Bars
- Yield Strength: 41,000 psi
- Hardness: Rockwell B88 (Medium)
- Temper Rating: Softened (Annealed)
- Specifications Met: ASTM B575
C-276 nickel has excellent corrosion resistance against chemicals, including nitric acid, sulfuric acid, and hydrochloric acid. It’s better than stainless steel at protecting from chloride pitting, so it’s often used around bleach in paper manufacturing. This alloy also will not develop stress cracks from contact with sulfides, making it good for use in petrochemical applications. C-276 nickel is easy to weld and remains corrosion resistant after welding. It retains its strength after being reshaped. C-276 nickel is comparable to Hastelloy C-276.

Wear-Resistant Cobalt 6 Sheets and Bars
- Yield Strength: 70,000 psi
- Hardness: Rockwell C38 (Hard)
- Heat Treatable: No
- Tensile Strength: 130,000 psi
Cobalt 6 is tough and wear resistant. It balances the properties of alloys with higher and lower carbon content, and is known for its all-around performance. With a wrought material structure, it withstands rapid changes in temperature, resists abrasion, and is four times as impact resistant as other cast materials made from the same chemicals. It won’t corrode or oxidize in extreme environments, so it’s commonly used in food-handling machinery and chemical equipment. Cobalt 6 slides against other materials without degrading, seizing, or galling, making it a good choice in areas that can’t be lubricated or for sliding parts such as sleeves. It also retains its properties at high temperatures. Unlike pure cobalt, it’s nonmagnetic, so it won’t cause damage when used in electrical systems. It’s also known as Haynes 6B and Stellite® 6B.

Peel-Away Layered Shim Stock
Cut this shim stock it into custom shapes to fit your application. Stock is made of layers of material bonded with adhesive; remove layers with a utility knife until you get the thickness you need. To make the layers easier to pull apart, gently heat the shim to soften the adhesive.
For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.
Aluminum shim stock is lightweight and nonmagnetic. It has good corrosion resistance.
