AISI 1040

It is a medium-carbon steel renowned for its balance of strength, toughness, and machinability.

Descriptions

1. Chemical Composition

AISI 1040 complies with the following chemical composition (weight %):

2. Mechanical Properties

Mechanical properties vary with heat treatment. Typical values for hot-forged and heat-treated AISI 1040:

3. Key Advantages

Excellent Weldability: Suitable for on-site repairs and modifications.

Cost-Effective: Lower material and processing costs compared to alloy steels.

Machinability: Easy to machine into complex shapes with standard tools.

Ductility: Resists fracture under bending or forming operations.

4. Limitations

Low Strength: Not suitable for high-stress or dynamic-load applications (e.g., drill collars, crusher jaws).

Poor Wear Resistance: Requires surface treatments (e.g., carburizing) for abrasive environments.

Corrosion Susceptibility: Needs coatings (galvanizing, painting) for outdoor or humid conditions.
