Carbon steel ball

hardened steel

More demanding to produce than case hardened Carbon Steel balls, we use a process that heats the steel beyond what's called its transition temperature - the point at which the actual structure is changed; the steel is then cooled so quickly that it maintains this high temperature state, resulting in a product that's more resilient and longer lasting than the case hardened version. Benefits Through Hardened High Carbon Steel Balls can handle much heavier loads than Case Hardened Balls - and they last longer. They're more expensive, but still much cheaper than Chrome Alloy Balls, striking an excellent balance between durability and value for money. In addition, because the hardness is added uniformly through the ball as opposed to just on the surface, they remain rigid and able to handle higher levels of stress even when under misalignment. Use Through Hardened High Carbon Steel Balls are used in bicycles, roller skates, shopping trolleys and locks - testament to their ability to handle the rough and tumble of day-to-day life.
