Nakamura Stainless is a well-respected manufacturer and supplier based in Pulau Ujong, Singapore, focusing on top-notch stainless steel products, including Stainless Steel 304 Flanges. The company has built a solid reputation for its precision, durability, and commitment to global standards, offering reliable solutions for industries that need strong and corrosion-resistant flanges. Known for their impressive strength and exceptional corrosion resistance, Stainless Steel 304 Flanges boast a long service life, making them ideal for both industrial and commercial uses. With rigorous quality control and prompt delivery, Nakamura Stainless guarantees dependable performance in every project.
These flanges are made from a blend of chromium (18–20%) and nickel (8–11%), along with low carbon content, manganese, silicon, and trace elements. This unique composition provides remarkable corrosion resistance, outstanding durability, and good formability. On the mechanical side, they deliver a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%, striking a balance between toughness and flexibility. Their excellent weldability and resistance to oxidation further boost their reliability, making them a go-to material for piping and structural connections in challenging environments.
