Martensitic High-Strength FV520B Stainless Steel Rod, Bright Rod, Hot-Rolled Plate For Petrochemical Industry
Introduction to FV520B Stainless Steel:
FV520B is a martensitic stainless steel that maintains good mechanical properties in low-temperature environments. Like general stainless steel, it has magnetism. Due to its special chemical composition, the smelting and processing of raw materials are relatively strict to ensure its corrosion resistance. FV520B also belongs to the precipitation hardening stainless steel series, which has high strength and can be divided into high-strength low-alloy series. The material is generally used for high-strength components, such as blades.
The advantages of FV520B stainless steel mainly include high strength, good corrosion resistance, impact toughness, and weldability.
High strength: FV520B stainless steel has extremely high strength, thanks to its excellent mechanical properties and good processability. It has very high tensile strength and yield strength, and can withstand enormous mechanical pressure and impact.
Good corrosion resistance: FV520B stainless steel can maintain good corrosion resistance in various corrosive environments, which enables it to be used for a long time in harsh environments without being damaged by corrosion.
Impact toughness: This material has good impact toughness, which can effectively absorb impact energy, prevent material cracking and breakage, and improve the safety and durability of the material.
Welding performance: FV520B stainless steel also has good welding performance, which can facilitate welding operations and improve manufacturing efficiency.
In addition, FV520B stainless steel also has good magnetic properties, which to some extent increases its application range. Its chemical composition and heat treatment process can be adjusted according to specific application requirements to achieve optimal mechanical properties.
Therefore, FV520B stainless steel is widely used in aerospace, petrochemical, automotive manufacturing, medical equipment, power industry and other fields, for manufacturing high-precision, high-strength, high corrosion resistant components and equipment.
The chemical composition of FV520B mainly includes elements such as carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S), chromium (Cr), nickel (Ni), molybdenum (Mo), copper (Cu), niobium (Nb), etc.
Carbon (C): 0.04-0.07%
Silicon (Si): ≤ 0.70%
Manganese (Mn): ≤ 1.00%
Phosphorus (P): ≤ 0.035%
Sulfur (S): ≤ 0.025%
Chromium (Cr): 13.0% -15.0%
Nickel (Ni): 5.00% -6.50%
Molybdenum (Mo): 1.20% -2.00%
Copper (Cu): 1.20% -2.00%
Niobium (Nb): 0.20% -0.70%
| C | Si | Mn | P | S | Cr | Ni | Mo | Cu | Nb |
