Table of Contents

Stainless steel 440B fasteners have high carbon composition (approximately 0.6–0.75%) and around 16–18% chromium content, enabling them to be heat-treated to attain high hardness and wear resistance. In comparison to 440A, 440B is more carbon content and provides better strength and durability. Although they offer moderate corrosion resistance, these fasteners are best utilized in dry or slightly corrosive environments. Martensitic structure provides tremendous mechanical strength, toughness, and fatigue life, thus making 440B fasteners ideal for high-wear and high-stress applications.
