Spherical Perfection In Steel Balls

Steel balls look like classy marbles. The shiny gleam and the glassy surface make them ideal as a play-toy, but that is not what they are used for—largely not anyway. Instead, a steel ball is one of the most important features in applications like antilock brakes, ball bearings, CV joints and seatbelt locks. In general, steel is the choice material for ball construction in the automotive and aerospace industry.

Steel outperforms other metals used to make balls such as chrome or tungsten carbide for its noncorrosive properties, hardness and cost efficiency. While chrome has many useful applications, it cannot be placed in environments where it is likely to often be wet or subject to fluid contamination. Though tungsten carbide is far harder and noncorrosive, its sheer expense makes it unavailable for most applications.

Steel is the ideal medium. Steel is swell resistant at only 6.4 microinches, per inch, per degree Fahrenheit. Simply stated, in a hot combustion engine, steel balls will not swell to larger sizes and cause abrasion to their components. Chrome and aluminum both swell more than twice as much in the same heat equations does. Again, tungsten carbide is more resistant but at a high cost.

Steel balls are the choicest product in their many applications. Many people are unaware of the numerous places where steel is the select material, and where balls are placed. For simple rolling appliances like hospital curtains, balls are used in most patient rooms. Everyone who has used a ballpoint pen has enjoyed the noncorrosive factors of steel for smooth writing. People whose lives have been saved by a seat belt locking in a bad car accident can thank steel. The metal is simply the most effective medium for the most useful shape: the sphere.

Numerous companies provide balls made from every material from glass to aluminum and of course, steel. Commonly, companies provide sizing-charts for clients to order, ranging from 1/64th of an inch to three inches. Smaller sizes are utilized for pen points while larger balls are used in pivot joint machinery like a sprinkler system. Special orders and companies with broader scoping machinery produce balls up to six inches in diameter. These larger sizes are most commonly utilized in airplane wing-flaps or as ball bearings for semis.

Only tungsten carbide has the ability to valve-stop gas piping for industries like Halliburton or Schlumberger, making it the winner of that competition. For the rest of the industry, there is steel, steel or steel. The most versatile metal known to man is steel. The most useful shape is the sphere. The two combine to make one of the most unassuming, and profound products on the market. The next time a person turns on his or her car, he or she should thank steel balls for the safety they have provided all these years.
