400 Nickel Machine Key Stock

Manufacturer part: 4428N13

Cut this square or rectangular key stock to length to create a straight machine key. Straight keys are the most common type of key. Machine keys are often the same material as the shaft and other components with which they are used. To use a key as a sacrificial part, choose a softer key that will shear off when parts are exposed to excessive force, preventing damage to expensive equipment.400 Nickel—400 nickel key stock is the most corrosion resistant key stock in our offering and can be used in highly corrosive environments, such as those involving salt water, sulfuric acid, and alkalies. For complete corrosion resistance, 400 nickel keys are typically used with 400 nickel machine parts. Comparable to Monel, 400 nickel is also known for its strength and weldability.Undersized Tolerance—Slightly smaller than the size listed in the table, undersized stock is the choice when you need a slightly looser fit or when you have an inconsistent keyway. Use it when parts need to be taken apart frequently, such as for maintenance or prototyping.
