Lecong Stainless, a top-notch manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Stainless Steel 440B Nuts that are perfect for high-strength fastening needs in tough environments. Crafted from martensitic stainless steel grade 440B, these nuts boast impressive hardness, wear resistance, and tensile strength. Thanks to their outstanding corrosion resistance and durability, Stainless Steel 440B Nuts find their place in various industries, including automotive, aerospace, machinery, and industrial equipment, ensuring secure and dependable connections even under intense stress and challenging conditions.
These nuts are primarily made up of iron, with a high carbon content (0.6–0.75%), chromium (16–18%), and trace amounts of manganese, silicon, and molybdenum. This unique blend gives them remarkable hardness, wear resistance, and mechanical strength. Plus, heat treatment can further boost their hardness and toughness. Mechanically, they deliver high tensile strength, good fatigue resistance, and reliable performance in moderately corrosive settings, making them a go-to choice for heavy-duty applications.
