AISI 3150 Bolting Products
AISI 3150 is listed in the NICKEL CHROMIUM 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 3150 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 3150 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 3150 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.
Nickel chromium steels are alloy steels used where improved hardenability, strength and toughness are required, with selected grades suited to case-hardening or through-hardening applications. Exact characteristics vary with the individual grade, product form and heat-treatment condition.
Nickel and chromium additions can improve hardenability and through-section response.
Nickel-containing alloy steel can provide useful toughness when properly selected and heat treated.
Selected grades are suitable for carburizing and related surface-hardening treatments.
Heat treatment allows the required strength and hardness to be developed for suitable applications.
AISI 3150 belongs to the nickel chromium 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.
Used for selected carburized and heat-treated gear applications.
Applied to shafts, axles and forged machine components.
Used in powertrain and other mechanically loaded components.
Selected grades are used where alloy-steel hardenability and toughness are needed.
Select the exact AISI 3150 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 3150 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.
