Steel is another heavily alloyed material allowing it to cost effectively cover many different product applications. Steel components are produced via the powdered metal/MIM process, as well as sand and investment casting. High strength, toughness, abrasion and wear resistance are typical reasons for specing steel in your applications.
Per usual powdered metal gives you the finest surface finish and closest near net shape of the processes. Casting allows you to make 100k pound parts and beyond!
All typical secondary capabilities can be performed including paint, plating,polishing, heat treat and machining. Machining runs a bit slower due to the general toughness of the material.
Production tooling follows the same path as the other noted materials we have been discussing.
Up front solidification modeling is great first step when analyzing your specific part needs.
