A widely used low-carbon steel valued for machinability, weldability, and consistent dimensional control.

Purchase to your specification

1018 for your next production order.

Send your 1018 requirement for a commercial quote. The grade is prefilled; add your dimensions and quantity, or attach the specification you already use.

Size & supply condition: State the diameter, length, and required condition. We confirm the available supply route against your order.
Finished to your requirement: Include production cutting, surface finish, tolerances, and any required heat treatment. Processing is reviewed with the material requirement.
Documentation & delivery: Specify mill certifications, testing, traceability, delivery date, and ship-to location so they can be included in the quote.

A grade name is the starting point. The governing specification, condition, dimensions, and testing define the material to be quoted.

1018 Round Bar: Material Profile

1018 is a general-purpose grade with clean machining and predictable forming response.

Cold-finished round bar is a common choice when the order calls for a smooth surface and close dimensional tolerances.

Purchase to the controlling ASTM, SAE, AMS, or customer specification. Section size, supply condition, mechanical properties, surface limits, testing, and heat/lot traceability can change the acceptable material and processing route.

Key Characteristics

Good machinability
Good welding characteristics
Consistent dimensions
Suitable for case hardening

Common Applications

Shafts and axles
Pins and dowels
Hinges
Machine parts and fasteners
