Forging improves the material’s grain structure, resulting in enhanced mechanical properties such as strength and toughness. The process can also improve the material’s resistance to fatigue and impact.

Q3: What is the difference between carbon steel and alloy steel in forging?

Carbon steel primarily contains iron and carbon, with no additional alloying elements. Alloy steel includes elements like chromium, molybdenum, and vanadium, which enhance specific properties such as hardenability, strength, and wear resistance.

Q4: Why is titanium alloy more expensive compared to other forging materials?

Titanium alloys are more expensive due to the high cost of raw titanium and the complex processing required to manufacture these alloys. However, their superior strength-to-weight ratio and corrosion resistance make them valuable for high-performance applications.

Q5: Can aluminum alloys be used in high-stress applications?

While aluminum alloys like 2024 and 6061 are strong and lightweight, they are generally used in less demanding applications compared to steels and titanium alloys. They are suitable for aerospace and automotive applications where weight reduction is critical.
