Carbon Steel
A material family for general mechanical parts where strength and cost need to be balanced.
SURFACE FINISHING
Black Oxide
A dark surface treatment for suitable ferrous materials.
Dark conversion finish
Specify the result you need.
Discuss the required protective treatment and service environment. Confirm appearance and inspection requirements with the material and process route.

Material families to review
Alloy Steel
Compare alloy steels for components with demanding mechanical requirements.
Compatibility depends on the specific grade, geometry and treatment specification. Final selection is reviewed with the project.
A finish belongs
in the drawing, too.
Identify visible surfaces, masking areas, contact points and fits. State whether your dimensional requirements apply to the finished part.
