Nakamura Stainless, located in Pulau Ujong, Singapore, stands out as a top manufacturer and supplier of high-quality stainless steel products that cater to a wide array of industries. One of their standout products, the Stainless Steel 202 Flanges, is highly regarded for its impressive strength, durability, and affordability. Designed for situations that need moderate corrosion resistance and robust mechanical properties, these flanges guarantee secure and lasting connections in piping systems. With a commitment to precision manufacturing, strict quality control, and timely delivery, Nakamura Stainless serves various sectors, including construction, petrochemical, marine, and engineering, providing dependable stainless steel solutions both in Singapore and around the globe.
Stainless Steel 202 Flanges are made up of chromium (17–19%), manganese (7.5–10%), and nickel (4–6%), which enhances their strength while keeping nickel content lower. They boast high tensile strength (approximately 515–620 MPa), good hardness, and moderate corrosion resistance, making them suitable for mildly aggressive environments. These flanges also offer excellent toughness, formability, and weldability, ensuring they perform reliably in challenging applications. Their well-balanced alloy composition helps them maintain structural integrity under pressure and stress, making them perfect for piping connections, flow control systems, and other industrial setups where durability and cost-effectiveness are key.
