AISI 9254 is listed in the SILICON MANGANESE STEEL material family. The reference data below should be checked against the governing product specification, product form and delivery condition before selection or certification.
The reference chemistry table for AISI 9254 lists Carbon (C): Grade-specific / specification dependent; Silicon (Si): Grade-specific / specification dependent; Manganese (Mn): Grade-specific / specification dependent; Chromium (Cr): Grade-specific / specification dependent. Confirm exact limits and analysis tolerances against the governing standard and product form.
The mechanical-property table for AISI 9254 lists Tensile Strength: Specification / condition dependent MPa; Yield Strength: Specification / condition dependent MPa; Elongation: Specification / condition dependent %; Hardness: Specification / condition dependent HB / HRC. These are reference entries; supplied condition, dimensions, test method and governing specification control the requirements, and the figures are not design allowables.
No one-to-one Werkstoff number was verified for AISI 9254 in the cross-reference sources checked for this update. Confirm any proposed EN alternative against the governing specification.

Indicative physical-property values for alloy steels; exact values vary by grade and should be confirmed from the relevant specification.
Silicon manganese steels are alloy steels commonly selected for spring applications because of their strength, resilience and fatigue performance after suitable heat treatment. Exact characteristics vary with the individual grade, product form and heat-treatment condition.
Suitable heat treatment can provide the strength and resilience required for spring service.
These steels are selected for components subjected to repeated loading.
Silicon and manganese alloying supports the required combination of strength and spring performance.
Final properties depend heavily on hardening and tempering parameters.
AISI 9254 belongs to the silicon manganese steel family and is selected for applications where the relevant strength, hardenability, wear resistance or toughness requirements are met by the specified grade and condition.
Commonly used for automotive and industrial coil springs.
Used for selected leaf-spring and suspension components.
Applied to resilient clips and retaining components.
Used where repeated loading and spring properties are critical.
Select the exact AISI 9254 specification, product form and supply condition according to the required strength, toughness, wear resistance and service environment.
Heat-treatment parameters are grade-specific. Use the applicable specification and qualified processing procedure for hardening, tempering or case hardening.
Final mechanical properties depend on grade, section size and material condition. Confirm the required tensile strength, yield strength and hardness before selection.
No one-to-one Werkstoff number was verified for AISI 9254 in the cross-reference sources checked for this update, so this page does not assign a number. Confirm any proposed EN alternative against the applicable product standard and supplier certificate before substitution.
The listed alloy-steel and tool-steel grades are generally selected for heat-treated service, but the exact treatment depends on the grade and required material condition.
Typical uses depend on the exact grade and condition and may include machinery parts, gears, shafts, fasteners, tooling or spring components within the relevant material family.
Use the applicable AISI, SAE or other governing specification and the material certificate for the supplied product form and condition.
