With a minimum of 10% chromium content, stainless steel is known for corrosion resistance. It's typically not as strong as steel and can be more difficult to machine.

A combination of high strength, hardness, and wear resistance makes tool steel especially well-suited for use as cutting tools.

Because Grade 2 titanium is 99% pure, it is more corrosion resistant than Grades 5 and 9 but not as strong. It has good formability and weldability. Common uses include chemical processing equipment, heat exchangers, and marine hardware.

This opaque and semi-clear plastic is often used in place of metal where a lightweight material is desired, such as for signs, equipment housings, and gears.
