Steel Wheels

Forged steel wheels are made from solid steel billets and are denser, heavier, and stronger. Pressed steel wheels are stamped from steel plate and are lighter for their size, making them easier to handle while still supporting heavy loads. Forged wheels are preferred for the most extreme loads and impact conditions. Pressed wheels are suitable for heavy-duty applications where some weight savings are beneficial.

Steel wheels operate continuously at temperatures from 600 to 800 degrees Fahrenheit or higher, depending on the specific steel grade. As with all metal wheels, the bearing and lubricant often determine the practical temperature limit rather than the wheel itself.

For loads above 3,000 to 5,000 lbs per wheel, steel is the better choice. Nylon wheels are excellent up to their rated capacity but cannot match the extreme load ratings of steel. Steel also handles high temperatures far beyond nylon's 250-degree limit. However, nylon offers chemical resistance and lower rolling noise that steel cannot provide.

Standard carbon steel wheels will develop surface rust in humid or wet environments. Zinc plating, chrome plating, or other protective finishes are available to reduce corrosion. For highly corrosive environments, stainless steel wheels or polymer alternatives with stainless hardware are better options.
