Understanding the Composition and Properties of L-NiCuCr202 Steel Grade

Steel grade L-NiCuCr202 is a high-strength, corrosion-resistant alloy that is commonly used in applications requiring excellent mechanical properties and good resistance to corrosion. The composition and properties of this steel grade are as follows:

Mechanical Properties:
– Ultimate Tensile Strength: 1100 MPa
– Yield Strength: 900 MPa
– Elongation at Break: 12%
– Hardness: 290 HB

Chemical Composition (in weight %):
– Nickel (Ni): 4.0 – 6.0%
– Copper (Cu): 1.0 – 2.0%
– Chromium (Cr): 19.0 – 21.0%
– Molybdenum (Mo): 0.5 – 1.0%
– Carbon (C): 0.05 – 0.15%
– Phosphorus (P): 0.03% max
– Sulfur (S): 0.03% max
– Iron (Fe): Balance

The high nickel, copper, and chromium content combined with molybdenum provides excellent corrosion resistance, particularly in acidic and high-temperature environments. The addition of carbon and molybdenum also contributes to the high strength and hardness of the alloy. The balance of iron ensures the structural integrity of the steel.

Overall, L-NiCuCr202 steel grade offers a combination of high strength, excellent corrosion resistance, and good mechanical properties, making it suitable for use in challenging environments such as marine applications, chemical processing, and aerospace components.
