Stainless steel is a metal alloy primarily composed of iron, chromium, and small amounts of other elements such as nickel and molybdenum. It exists to provide improved resistance to corrosion, enhanced strength, and long-term durability compared to ordinary carbon steel.
Stainless steel was developed to address the problem of corrosion in metals exposed to moisture, air, and chemicals. By adding chromium, a protective oxide layer forms on the surface, preventing rust and improving durability.
Today, stainless steel is widely used in construction, manufacturing, transportation, medical equipment, food processing, and energy systems. Its unique properties make it suitable for demanding environments where strength and resistance are essential.
