AISI 1030
Widely used in forged components requiring moderate wear resistance and load-bearing capacity, it finds applications across industries such as oil & gas, mining, automotive, and general machinery.
Descriptions
1. Chemical Composition
AISI 1030 complies with the following composition (weight %):
| Element | Content (%) |
| Carbon (C) | 0.28-0.34 |
| Manganese (Mn) | 0.60-0.90 |
| Phosphorus (P) | ≤0.040 |
| Sulfur (S) | ≤0.050 |
| Silicon (Si) | ≤0.40 |
| Iron (Fe) | Balance |
2. Mechanical Properties
Properties depend on forging processes and heat treatments. Typical values for hot-forged and normalized AISI 1030:
| Property | Value |
| Tensile Strength | 500-700 MPa(72-102 ksi) |
| Yield Strength | 350-550 MPa(51-80 ksi) |
| Elongation (50mm) | 12-20% |
| Hardness | 150-200 HB(Brinel1) |
| Impact Energy (Charpy V-notch) | 15-30J(11-22 ft-1b)at 20°C |
3. Key Advantages
Cost-Effective Strength: Higher strength than low-carbon steels (e.g., AISI 1020) at a moderate cost.
Machinability: Easily machined in annealed or normalized conditions.
Heat Treatability: Responds well to Q&T for enhanced mechanical properties.
4. Limitations
Corrosion Susceptibility: Requires coatings (e.g., galvanizing, painting) for humid or corrosive environments.
Weldability Challenges: Preheating and post-weld heat treatment are necessary to avoid cracking.
Limited Wear Resistance: Needs surface hardening for abrasive applications.
5. Comparison with Similar Grades
| Material | Strengths | Weaknesses vs. AISI 1030 |
| AISI 1020 | Better weldability and ductility | Lower strength(380-550 MPa tensile) |
| AISI 1045 | Better weldability and ductility tensile) | PaPoorer machinability and weldability |
| AISI4140 | Superior strength and corrosion resistance | Higher cost and complex heat treatment |
