Composition and Corrosion Resistance of Stainless Steel
Stainless Steel is a high-performance alloy primarily composed of iron and chromium, with a chromium content ranging from 10% to 12% or higher. Depending on the desired properties, it may also include nickel, molybdenum, tungsten, and other elements that enhance its strength, durability, and resistance to corrosion.
One of the most remarkable features of Stainless Steel is its exceptional resistance to oxidation and chemical attack. This property comes from the presence of chromium, which reacts with oxygen to form a thin but extremely stable passivating oxide layer on the surface. This invisible film protects the metal from rust, moisture, and aggressive environmental agents, maintaining its integrity and appearance over time.
Thanks to this natural protective barrier, Stainless Steel is capable of maintaining its mechanical properties even under extreme conditions of humidity, temperature, and chemical exposure. The addition of nickel increases ductility and toughness, while molybdenum and tungsten contribute to superior resistance against acids, chlorides, and wear.
This unique composition makes Stainless Steel a versatile material widely used in industrial manufacturing, construction, automotive, and energy sectors, where reliability and long service life are essential. Whether in precision components, structural supports, or high-performance assemblies, Stainless Steel offers an optimal balance between strength, appearance, and corrosion resistance, making it one of the most trusted materials in engineering today.
