Lecong Stainless, a top-notch manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Stainless Steel 440C Bolts that are perfect for applications demanding exceptional hardness, wear resistance, and strength. Crafted from high-carbon martensitic stainless steel, these SS 440C bolts are renowned for their outstanding performance in tough environments, all while offering moderate corrosion resistance. Thanks to their ability to reach maximum hardness after heat treatment, these bolts find their way into various sectors, including aerospace, automotive, marine, defense, and heavy machinery. Lecong Stainless takes pride in ensuring that every bolt meets international standards, providing long-lasting durability, precision, and reliable fastening solutions for critical applications.
Stainless Steel 440C Bolts are made with high carbon content and 16–18% chromium, which gives them excellent hardness and abrasion resistance, along with protection against oxidation. After undergoing heat treatment, these bolts can achieve a hardness of up to 60 HRC, guaranteeing remarkable tensile and compressive strength even under intense stress. Mechanically, SS 440C bolts showcase superior toughness, strength, and wear resistance, making them ideal for environments that experience friction, heavy loads, and high pressure. While their corrosion resistance may not match that of austenitic stainless steels, their unparalleled mechanical strength makes them a go-to choice for extreme service conditions.
