What is the best material for Carburizing?

The best metals for carburizing are 8620 and 9310 steel.

What’s the difference between a metallurgist and a materials engineer?

A metallurgist focuses primarily on heavy and light metals. A materials engineer focuses on metals, plastics, and other materials. Generally speaking, the degree of “Metallurgist” has been replaced by the degree of “Materials Engineer” or “Materials Scientist” at most colleges.

Do you have a specialized metallurgist I can talk with?

Yes, we have 3 materials engineers you can talk with. We also have an industrial engineer, and a mechanical engineer.

Will material change size during the heat treating process?

Generally it may. There are many reasons that material changes size or distorts, but we’ll need more information to give you an exact answer.

What are wear resistance applications?

Wear resistance applications include types of Case Hardening such as nitriding and carburizing. A few other wear resistance applications like Induction Hardening and Carbonitriding are also ways to harden the surface of a material.
