About Washer Materials Finish/Coating Features Plain Good or general purpose applications. Zinc-Plated Offers good rust resistance. Cadmium-Plated Perfect for environments where corrosion protection is essential. Ultra-Coated A water-based inorganic coating that provides better corrosion resistance than hot-dipped galvanized. Galvanized Provide better corrosion resistance than zinc-plated steel. Nickel-Chrome Plated Polished and buffed to a mirror-like finish for a bright, decorative appearance. Resists wear and corrosion. Nickel-Plated Adds an attractive appearance. Black Offers mild rust resistance and some lubricity. Black Luster-Coated Offers a durable and decorative finish. Provides corrosion resistance superior to black-finish and zinc-plated finishes. Aluminum-Backed Made of Alloy 5052 Aluminum. Neoprene-Backed/Silicone-Backed Strong yet soft and resilient enough to use with fragile materials. Material Type Features Steel For general purpose applications. Precipitation- Hardened (17-7 PH) Stainless Steel Suitable for use in conditions where steel, no matter how well plated, cannot survive. Retains the strength and hardness of heat-treated steel with the corrosion resistance of stainless steel. 18-8 Stainless Steel Offers excellent corrosion resistance; it may be mildly magnetic. Alloy 20 Stainless Steel Also known as Carpenter 20, offers superior resistance to sulfuric acid and stress corrosion. 301/302 Stainless Steel Has good corrosion resistance. 304 Stainless Steel The most widely used stainless steel. Has good resistance to high temperatures and corrosion. 316 Stainless Steel Better corrosion resistance than 18-8 stainless steel, plus withstands many chemicals and solvents. 410 Stainless Steel Corrosion resistant and magnetic. Aluminum 1100F As strong as mild steel and just one-third the weight, aluminum resists weather-related corrosion. Aluminum 2024-T4 Nonmagnetic aluminum is heat treated for additional hardness. As strong as mild steel and just one-third the weight, resists weather-related corrosion.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
