Nakamura Stainless stands out as a top-notch manufacturer and supplier based in Pulau Ujong, Singapore, specializing in high-quality stainless steel products, including Stainless Steel 304H Flanges. Known for their reliability and precision, they cater to industries that require durable and high-performance materials. These flanges are crafted with a higher carbon content, which gives them exceptional strength and toughness at elevated temperatures, along with impressive corrosion resistance. With a commitment to strict quality standards, advanced manufacturing techniques, and prompt delivery, Nakamura Stainless guarantees that their 304H Flanges meet international standards for both industrial and commercial uses.
The composition of Stainless Steel 304H Flanges includes chromium (18–20%), nickel (8–11%), and an increased carbon content of up to 0.10%, along with manganese, silicon, and trace elements. This blend not only boosts high-temperature strength but also enhances creep resistance while ensuring excellent corrosion resistance. On the mechanical side, they boast a tensile strength of about 515 MPa, a yield strength of around 205 MPa, and an elongation of 40%, which together ensure toughness and durability in challenging environments. These well-balanced properties make Stainless Steel 304H Flanges perfect for high-temperature and pressure applications.
