Our materials meet strict international standards and are widely used in automotive, oil & gas, and general engineering applications where through-hardening performance is essential.

What Is 535A99 Through Hardening Steel?

535A99 is a nickel-chromium-molybdenum alloy steel grade defined under British Standard BS970:1955. It is specifically designed for through hardening, which means it achieves a uniform hardness and strength across the entire cross-section after heat treatment — not just at the surface.

This makes 535A99 an excellent choice for heavy-duty components exposed to torsional stress, fatigue, and impact. The alloy’s blend of nickel, chromium, and molybdenum gives it superior toughness, high tensile strength, and wear resistance.

Typical uses include gears, shafts, connecting rods, and high-performance mechanical components requiring consistent hardness throughout.

Key Features and Benefits

• Uniform Hardness: Through-hardens across large diameters for consistent mechanical strength.
   
• Excellent Strength and Toughness: Handles high loads, impacts, and stress cycles.
   
• Superior Wear Resistance: Ideal for rotating, sliding, or heavily loaded parts.
   
• Good Machinability: Easy to machine in the annealed condition.
   
• Heat-Treatable: Can be hardened, tempered, or nitrided to suit specific requirements.
   
• Reliable Fatigue Resistance: Performs well under repetitive stress and vibration.
   
• Dimensional Stability: Maintains form after heat treatment or machining.

These advantages make 535A99 a preferred alloy for demanding mechanical and structural applications.
