20CrMnTi Alloy Steel Gear Forgings – Normalized and Tempered for Crusher Gear Applications.
These gear forgings are made from high-quality 20CrMnTi alloy steel, known for its excellent hardenability, wear resistance, and impact strength.
Specially designed for crusher gear applications, the forgings undergo normalizing and tempering to enhance their toughness, improve internal structure, and ensure long-lasting performance under high-impact, high-load conditions.
The forged construction ensures superior mechanical properties and eliminates common casting defects, making these components ideal for heavy-duty equipment in mining, construction, and aggregate crushing industries.
