When choosing a steel for your project there are a few characteristics to consider:

Hot rolled / Hot finished

Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700° F), Hot rolled steel is typically cheaper than cold rolled. When the steel cools off it will shrink slightly thus giving less control on the size and shape of the finished product when compared to cold rolled. Hot rolled steel is used in situations where precise shapes and  tight tolerances are not needed.

Common grades we machine:

  • 1018
  • 1045
  • A36
  • A513
  • 4000 Series

Cold rolled / Cold finished

Cold rolled steel is basically hot rolled steel that has had additional processing when the material is cooled, annealing and/or rolled. When compared to hot rolled this will produce steel with more controlled dimensional tolerance and a better surface finish.

Your bar stock will also have better concentricity and straightness when compared to hot rolled.

Common grades we machine:  

  • 12L14
  • 1215
  • 1144
  • 1141
  • 1000 Series

Tool steel

Tool steel is a type of carbon alloy steel that is well-matched for tool manufacturing, such as hand tools or machine dies. Tool steel is typically machined in an annealed state then heat treated for increased hardness.

Common grades we machine:

  • T5
  • E52100
