MATERIAL INTRODUCTION

AISI 4047H

The reference chemistry table for AISI 4047H 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 4047H 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 4047H in the cross-reference sources checked for this update. Confirm any proposed EN alternative against the governing specification.

MATERIAL CHARACTERISTICS

Molybdenum Steel

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.

01

Alloyed Strength

Molybdenum contributes to the performance of heat-treated low-alloy steels.

02

Hardenability

Selected grades are used where greater hardenability is required than plain carbon steel can provide.

03

Heat-Treatment Flexibility

Grade-specific treatment can be used to achieve required strength, hardness and toughness.

04

Machining and Fabrication

Machinability and fabrication response depend on grade and material condition.

ENGINEERING GUIDE

Engineering Considerations

Material Selection

Select the exact AISI 4047H specification, product form and supply condition according to the required strength, toughness, wear resistance and service environment.

Heat Treatment

Heat-treatment parameters are grade-specific. Use the applicable specification and qualified processing procedure for hardening, tempering or case hardening.

Mechanical Requirements

Final mechanical properties depend on grade, section size and material condition. Confirm the required tensile strength, yield strength and hardness before selection.

COMMON QUESTIONS

Frequently Asked Questions

What is the Werkstoff number for AISI 4047H?

No one-to-one Werkstoff number was verified for AISI 4047H 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.

Is AISI 4047H heat treatable?

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.

Where is AISI 4047H used?

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.

Where can the exact technical values be confirmed?

Use the applicable AISI, SAE or other governing specification and the material certificate for the supplied product form and condition.
