Mbemba Stainless is a reliable manufacturer and supplier located in Kinshasa, Congo, specializing in top-notch Stainless Steel 440C Stud Bolts. These stud bolts are crafted from high-carbon martensitic stainless steel, which is celebrated for its remarkable hardness, wear resistance, and decent corrosion resistance. At Mbemba Stainless, they prioritize precision manufacturing, rigorous quality control, and adherence to international standards. Their SS 440C stud bolts are perfect for applications that demand high mechanical strength, durability, and dependable fastening in industries like chemical, petrochemical, marine, and industrial machinery.
The composition of Stainless Steel 440C Stud Bolts includes 16–18% chromium, 0.95–1.2% carbon, along with trace amounts of manganese, silicon, and molybdenum. This blend results in a tensile strength ranging from about 760 to 1,200 MPa and impressive hardness after heat treatment, coupled with excellent wear resistance. The elevated levels of carbon and chromium enable the material to achieve outstanding hardness and mechanical strength, making it ideal for components that face heavy stress and abrasive conditions.
