Stainless steel is an alloy primarily composed of iron, carbon, and a minimum of 10.5% chromium. This unique composition grants stainless steel its notable resistance to corrosion and oxidation, making it an ideal material for foundation bolts, especially in environments where exposure to moisture, chemicals, or extreme temperatures is a concern. The alloying elements in stainless steel also contribute to its strength and durability, ensuring that foundation bolts can withstand significant stresses without deforming or breaking.
