Nakamura Stainless is a top-notch manufacturer and supplier located in Pulau Ujong, Singapore, known for its extensive range of high-quality stainless steel products. One of their standout offerings is the Stainless Steel 347 Nuts, crafted to meet the demanding needs of various industries. These nuts are meticulously engineered to deliver outstanding strength, durability, and resistance to corrosion. With cutting-edge manufacturing techniques and rigorous quality control, Nakamura Stainless guarantees that every product meets international standards. Committed to reliability and customer satisfaction, the company provides customized solutions for sectors like chemical, aerospace, and marine.
The Stainless Steel 347 Nuts are primarily made of iron, with 17–19% chromium, 9–13% nickel, and 1–2% niobium (columbium), which boosts their corrosion resistance and helps prevent intergranular attack. They also contain small amounts of manganese, silicon, and carbon to enhance their mechanical properties. These nuts boast a tensile strength of about 515 MPa and a yield strength close to 205 MPa. They excel in both oxidizing and acidic environments, and their stability at high temperatures makes them perfect for applications that require resistance to stress corrosion cracking and high-temperature corrosion.
