The chemical composition of GGL NiCr202 Steel consists of:

– Nickel (Ni): 58-63%
– Chromium (Cr): 18-22%
– Manganese (Mn): ≤ 2%
– Silicon (Si): ≤ 0.7%
– Carbon (C): ≤ 0.15%
– Phosphorus (P): ≤ 0.04%
– Sulfur (S): ≤ 0.03%

The mechanical properties of GGL NiCr202 Steel include:

– Tensile Strength: ≥ 550 MPa
– Yield Strength: ≥ 240 MPa
– Elongation: ≥ 30%
– Hardness: ≤ 217 HB

The technical properties of GGL NiCr202 Steel are:

– Density: 8.08 g/cm3
– Melting Point: 1370-1425°C
– Electrical Conductivity: 12% IACS (International Annealed Copper Standard)
– Thermal Conductivity: 11.4 W/m·K
– Coefficient of Thermal Expansion: 13.5 µm/m·°C (20-100°C)
– Magnetic Permeability: 1.01

These properties make GGL NiCr202 Steel highly suitable for marine environments due to its exceptional corrosion resistance. It is particularly resistant to localized corrosion, such as pitting and crevice corrosion, which are common in saline environments. Additionally, its high strength and good ductility make it suitable for various structural applications in marine equipment, such as shipbuilding and offshore structures. The steel’s chemical composition, along with its mechanical and technical properties, combine to provide a reliable and durable solution for combating the corrosive effects of seawater and other marine environments.
