The Stainless Steel Hard and Half Hard Coils from Mitchell Stainless are typically crafted from grades like 301, 304, and 316, which offer impressive chromium and nickel content for outstanding corrosion resistance. These coils are designed with enhanced tensile strength, hardness, and elasticity, thanks to controlled cold working processes. Hard coils deliver maximum rigidity, while half hard coils strike a perfect balance between formability and strength. Their mechanical properties include high yield strength, remarkable fatigue resistance, and exceptional durability, making them perfect for demanding applications that require precision and a long service life.
