Key Characteristics and Benefits of FV520B 

FV520B stainless steel is valued for its balanced set of properties, which make it a versatile solution for high-stress applications. When properly heat-treated, the material delivers a unique combination of mechanical strength and environmental resistance that outperforms many conventional stainless steel grades. 

• Excellent Mechanical Strength: Following solution treatment and aging, FV520B achieves high tensile and yield strength, allowing it to withstand heavy loads and high operational stresses. 
• Good Corrosion and Oxidation Resistance: Its chromium and molybdenum content provides robust resistance to atmospheric corrosion, fresh water, and many mild chemical environments, making it suitable for marine and industrial applications. 
• Superior Fatigue Strength and Wear Resistance: The alloy's martensitic structure and precipitated hardening phases contribute to excellent fatigue life and resistance to wear, which is essential for rotating or cycling components like shafts and blades. 
• High-Temperature Performance: FV520B maintains its structural integrity and strength at elevated temperatures, performing reliably in applications such as gas turbine engines and power generation components. 
• Customizable Hardness via Heat Treatment: You can tailor the material's final properties by adjusting the aging temperature. This allows for a precise balance between hardness, strength, and toughness to match your application's specific requirements. 
• Dimensional Stability: The alloy exhibits excellent dimensional stability under load and during temperature fluctuations, ensuring that precision components maintain their shape and tolerances during service.
