1. What is 50CrV4 Sheet & Plate?
50CrV4 is a high-performance spring steel, known for its toughness, shock resistance, and shallow hardening properties. This chromium vanadium steel grade offers excellent fatigue and impact resistance when heat-treated, making it ideal for use in demanding applications where durability is critical. 50CrV4 is extensively used in the production of gears, pinions, springs, shafts, axles, and other components that require a high modulus of resilience.
2. What is EN47 Sheet & Plate?
EN47 is a high-quality chromium vanadium spring steel that contains approximately 0.50% carbon. It is primarily used for components that require excellent wear resistance, such as springs and automotive parts. This steel is known for its high hardness after oil hardening and tempering, making it suitable for heavy-duty applications. EN47 can be supplied in sheet, plate, and round bar forms, and is widely utilized in industries that require superior strength and durability.
3. Chemical Composition of 50CrV4 & EN47 Steel
| Element | 50CrV4 (Min – Max %) | EN47 (Min – Max %) |
|---|---|---|
| Carbon (C) | 0.50 – 0.55 | 0.50 – 0.55 |
| Chromium (Cr) | 1.00 – 1.20 | 1.00 – 1.20 |
| Manganese (Mn) | 0.70 – 0.80 | 0.70 – 0.80 |
| Vanadium (V) | 0.15 – 0.25 | 0.15 – 0.25 |
| Silicon (Si) | 0.20 – 0.35 | 0.20 – 0.35 |
