When manufactured in bar form, the D3 Steel Bar provides machinability, consistent strength, and durability that can be used for cutting, forming, stamping, and shaping applications.
Key properties of D3 Steel Bar include:
-
High hardness (after heat treatment, up to 60 HRC)
-
Excellent wear resistance
-
High dimensional stability
-
Corrosion resistance in comparison to regular carbon steels
-
Good compressive strength
These properties make D3 Steel Bar suitable for industries where heavy-duty equipment and long-lasting components are required.
