AISI 4032 Bolting Products
AISI 4032 is listed in the MOLYBDENUM 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 4032 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 4032 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 4032 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.
Molybdenum alloy steels use molybdenum as a principal alloying addition to support hardenability, strength and performance in engineered components. Exact characteristics vary with the individual grade, product form and heat-treatment condition.
Molybdenum contributes to the performance of heat-treated low-alloy steels.
Selected grades are used where greater hardenability is required than plain carbon steel can provide.
Grade-specific treatment can be used to achieve required strength, hardness and toughness.
Machinability and fabrication response depend on grade and material condition.
AISI 4032 belongs to the molybdenum 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 shafts, gears and other machine components.
Applied to forgings requiring controlled strength and hardenability.
Suitable grades are used for highly loaded rotating and pinned components.
Used in engineered steel parts where alloyed, heat-treated performance is required.
Select the exact AISI 4032 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 4032 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.
