AISI 1045
It belongs to the SAE/AISI 10XX series (plain carbon steels) and is commonly employed in heavy-duty mechanical components, automotive systems, and industrial machinery.
Descriptions
1. Chemical Composition
The chemical composition of AISI 1045 (per ASTM A29/A29M and SAE J403 standards) is:
2. Mechanical Properties
Typical mechanical properties for AISI 1045 forgings (as-forged or heat-treated):
3. Key Advantages
High Strength-to-Cost Ratio: Excellent for heavy-load applications.
Machinability: Good in annealed condition; harder after heat treatment.
Heat Treatability: Responds well to quenching and tempering for tailored properties.
Wear Resistance: Suitable for components subject to abrasion.
4. Limitations
Weldability: Poor due to high carbon content; requires pre/post-heating.
Corrosion Sensitivity: Needs coatings (e.g., galvanizing, painting) for harsh environments.
Brittleness Risk: Overheating during forging or heat treatment can cause cracking.

Forging Process Guidelines
Hot Forging Temperature: 1150–1250°C (2100–2280°F)
Post-Forging Heat Treatment:
Annealing: 650–700°C (1200–1290°F) to improve machinability.
Quenching: Oil/water cooling from 830–850°C (1526–1562°F).
Tempering: 400–600°C (750–1112°F) to balance strength and toughness.
Applications
