Lecong Stainless, a top-notch manufacturer and supplier based in Da Nang, Vietnam, specializes in high-quality Stainless Steel 440C Stud Bolts that are built for strength, hardness, and durability. Crafted from high-carbon martensitic stainless steel, these stud bolts are engineered to perform exceptionally well in tough environments. With outstanding wear resistance, impressive tensile strength, and decent corrosion protection, SS 440C Stud Bolts find their place in various industries, including aerospace, marine, automotive, defense, and heavy engineering. Lecong Stainless takes pride in ensuring that every stud bolt meets international standards, providing reliable fastening solutions that promise a long service life, precision, and top-notch performance, even in the most extreme conditions.
These Stainless Steel 440C Stud Bolts contain 16–18% chromium and a high carbon content, allowing them to reach hardness levels of up to 60 HRC after heat treatment. This unique composition offers excellent resistance to abrasion and heavy stress, along with superior compressive and tensile strength. While their corrosion resistance may not be as high as that of austenitic grades, their mechanical properties—especially hardness, toughness, and wear resistance—make them a go-to choice for high-stress applications.
