| Grade | EN31 |
| Product Form | Round Bar |
| Thickness / Diameter | 25mm to 90mm |
EN31 is a high-carbon chromium alloy steel known for its high hardness, excellent wear resistance, and high fatigue strength. It retains dimensional stability after heat treatment and is widely used for high-precision, wear-resistant components such as bearings and shafts.
Equivalent to AISI 52100 / SAE 52100 / 100Cr6, EN31 is typically supplied in round bar form for machining into critical parts requiring superior surface hardness and durability.
Chemical Composition (Typical %)| Element | Range |
|---|---|
| Carbon (C) | 0.95 – 1.10% |
| Chromium (Cr) | 1.30 – 1.65% |
| Manganese (Mn) | 0.25 – 0.45% |
| Silicon (Si) | 0.15 – 0.35% |
| Phosphorus (P) | ≤ 0.025% |
| Sulphur (S) | ≤ 0.025% |
