Thread Rolling Materials
Mild steel bars are usually rolled without chamfering ends of bars. As hardness increases, chamfering should be considered. When approaching the 30 RC range and harder, chamfering is needed. The harder the material, the flatter the chamfer needed, and the chamfer should be slightly below the root diameter of the rolled thread.

Typical Thread Finishes for Average Threads
Rolled Threads - 4 - 32m/in.
Ground Threads - 16 - 32m/in.

1018 Low Carbon Steel
This type of steel is very desirable and one of the most widely used types of steel.

12L14
These steels roll satisfactorily in vee threads, but are not good for deep and wide forms due to the high lead content.

1215
These steels are free machining (high sulfur), and have the tendency to flake with acme and other wide root forms.

4140
This steel rolls well and results in an excellent finish.

Stainless Steel
304 - 316 stainless steel work hardens, but rolls well. Work finishes with a very small crest seam.
