38CrMoAlA/1.8509 Alloy Steel Round Bar
Material Standard: DIN 1.8509 / GB/T 3077 (Equivalent to Chinese Standard)
Overview
38CrMoAlA (DIN 1.8509) is a high-quality chromium-molybdenum-aluminum alloy steel specifically designed for nitriding treatment. It exhibits exceptional surface hardness, wear resistance, and fatigue strength after nitriding, making it ideal for high-stress components requiring superior durability and dimensional stability.
Chemical Composition
| Element | C | Cr | Mo | Al | Mn | Si | P (max) | S (max) |
|---|---|---|---|---|---|---|---|---|
| % | 0.35-0.42 | 1.35-1.65 | 0.15-0.25 | 0.70-1.10 | 0.30-0.60 | 0.20-0.45 | 0.025 | 0.025 |
Mechanical Properties (After Heat Treatment)
-
Tensile Strength: 980-1180 MPa
-
Yield Strength: ≥ 835 MPa
-
Elongation: ≥ 14%
-
Reduction of Area: ≥ 50%
-
Impact Energy (Charpy): ≥ 63 J
-
Surface Hardness (Post-Nitriding): 900-1000 HV
Heat Treatment
-
Normalizing: 870-900°C, air-cooled
-
