655M13 Case-Hardening Steel | Supplier & Stockist

Nifty Alloys LLC is a trusted supplier and stockist of 655M13 Case-Hardening Steel based in the UAE, serving industries across the Middle East and exporting globally. 655M13 steel is a nickel-chromium-molybdenum alloy steel known for its exceptional wear resistance, core strength, and ability to be case-hardened for high-stress engineering applications.

When you need reliable performance under pressure, 655M13 delivers both a tough interior and a hard, wear-resistant surface—making it ideal for gears, shafts, and heavy-duty components.

What Is 655M13 Case-Hardening Steel?

655M13 (equivalent to AISI 9310 or EN 17NiCrMo6-4) is a low-carbon, nickel-chromium-molybdenum steel developed specifically for carburizing (case hardening) applications. It offers a strong, ductile core combined with a highly hardenable surface, providing the perfect balance between toughness and wear resistance.

Once case-hardened, 655M13 achieves a surface hardness of up to 60 HRC, making it suitable for critical moving parts that require long service life under load.
