What Is Stainless Steel?
Stainless steel is an iron-based alloy containing a minimum of 10.5% chromium, which creates a thin, self-healing oxide layer that protects the material from corrosion and oxidation. Depending on the alloy composition, stainless steel may also contain nickel, molybdenum, manganese, titanium, or other elements that enhance strength, corrosion resistance, weldability, and high-temperature performance.
Available in a wide range of grades and finishes, stainless steel is valued for its durability, low maintenance requirements, and ability to perform in environments exposed to moisture, chemicals, extreme temperatures, and demanding sanitary conditions.
From structural components to precision-machined parts, stainless steel remains one of the most trusted materials across virtually every major industry.
