When your engineering projects demand high strength, consistent hardness, and reliability under load, 535A99 Through Hardening Steel is an ideal choice. This nickel-chromium-molybdenum alloy steel delivers exceptional core strength, fatigue resistance, and toughness throughout large cross-sections.
At Nifty Alloys LLC, we supply certified 535A99 Through Hardening Steel in bars, plates, and rods across the UAE, Saudi Arabia, Oman, Qatar, and the Middle East. Our materials meet strict international standards and are widely used in automotive, oil & gas, and general engineering applications where through-hardening performance is essential.
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.
