Product Description
30CrMnSiA Alloy Steel Round Bar
30CrMnSiA is a high-strength chromium-manganese-silicon alloy structural steel, widely used in aerospace, defense, and heavy machinery applications. Supplied in round bar form, it offers an excellent balance of strength, toughness, and hardenability, making it suitable for demanding load-bearing components.
High Strength Good Hardenability Excellent Toughness Wear Resistant
Key Characteristics
- High tensile strength and yield strength after quenching and tempering
- Good hardenability suitable for medium to large cross-section components
- Excellent combination of strength and toughness
- Good machinability in the annealed condition
- Suitable for welding with appropriate preheat and post-weld treatment
Typical Applications
- Aircraft structural components and landing gear parts
- High-strength bolts, shafts, and gears
- Connecting rods and transmission components
- Pressure vessels and high-load mechanical parts
- defense equipment components
