1518 Round Steel Bar

A low-carbon, high-manganese steel used for carburized or forged parts requiring improved hardenability and core strength.

Purchase to your specification

1518 for production and repeat supply.

Buying 1518 for machining, forging, or component production? Send your dimensions, condition, and quantity per order. For repeat supply, include annual usage and release timing, or attach your existing RFQ.

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.

1518 Round Bar: Material Profile

1518 contains more manganese than standard 10XX grades, supporting deeper hardening and stronger cores after carburizing.

Match the carburizing cycle, case depth, core properties, and bar condition to the finished-part design.

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 case-hardening response
Improved core strength
Good forging characteristics
Good machinability before hardening

Common Applications

Gears and pinions
Shafts and bushings
Forged automotive parts
Wear-resistant machine components

Specification Requirements

Identify the governing specification and revision, product form, section size, condition, mechanical properties, testing, and certification requirements. The purchase specification and material certification govern the order.
