Nakamura Stainless is a reputable manufacturer and supplier based in Pulau Ujong, Singapore, known for delivering top-notch stainless steel products that are built to last, resist corrosion, and perform reliably. One of their standout offerings is the Stainless Steel 405 Pipes, which are highly regarded for their impressive oxidation resistance, moderate corrosion resistance, and ability to withstand heat. This ferritic stainless steel grade is specifically designed for long-lasting performance in automotive, industrial, and HVAC applications. Adhering to international standards, Nakamura Stainless guarantees that their Stainless Steel 405 Pipes provide consistent quality, dimensional stability, and dependable service across a range of industrial and engineering piping systems.
These Stainless Steel 405 Pipes are made from ferritic stainless steel that contains 11–13% chromium, with a low carbon content (maximum of 0.08%) and trace amounts of titanium to boost corrosion resistance and prevent sensitization. This unique composition offers good tensile strength, toughness, and resistance to oxidation at high temperatures. Thanks to their ferritic structure, these pipes ensure excellent dimensional stability, mechanical durability, and reliable performance during thermal cycling, making them ideal for exhaust systems, heat exchangers, and industrial ducting.
