EN31 Steel | High Carbon Alloy Steel Supplier in UAE – Nifty Alloys LLC

EN31 steel is a high carbon alloy steel distinguished by its chromium content, which imparts exceptional hardness, strength, and wear resistance. This through-hardening bearing steel is engineered for applications demanding superior performance under high stress and abrasive conditions. Its primary use is in the manufacturing of high-precision components such as ball and roller bearings, shafts, bushings, and wear-resistant tooling. For industries where reliability and durability are paramount, EN31 provides a proven and effective material solution.

Nifty Alloys LLC is a trusted EN31 steel supplier in the UAE, providing certified materials that meet rigorous international standards. We specialize in delivering high-quality EN31 round bars, plates, and custom-cut profiles to engineering, manufacturing, and industrial clients across the GCC and beyond. Our commitment is to supply materials that ensure operational excellence, backed by comprehensive technical support and reliable logistics.

Key Features of EN31 Steel

EN31 steel is defined by a set of core features that make it a superior choice for high-performance applications.

• High Surface Hardness: Achieves up to 62 HRC after hardening and tempering, providing exceptional resistance to indentation and surface wear.
• Excellent Wear and Fatigue Resistance: Engineered to withstand continuous rolling contact and cyclic loading, making it ideal for bearings and high-duty cycle components.
• Good Dimensional Stability: Maintains its shape and tolerances well after heat treatment, which is essential for precision engineering.
• High Polishability: Can be polished to a mirror finish, a requirement for certain bearing surfaces and high-quality tooling.
• Moderate Machinability: In its annealed state, EN31 offers good machinability, allowing for complex components to be manufactured before the final hardening process.
