Emilio Stainless is a reputable manufacturer and supplier located in Manila, Philippines, specializing in top-notch stainless steel products like Stainless Steel 304H Nuts. With a strong focus on precision engineering and durability, Emilio Stainless is dedicated to delivering fastening solutions that adhere to international standards for mechanical strength and corrosion resistance. Their Stainless Steel 304H Nuts are expertly crafted to excel in high-temperature and high-pressure settings, guaranteeing reliable and long-lasting performance in even the most demanding industrial applications.
These Stainless Steel 304H Nuts are made from a high-carbon variant of the austenitic stainless steel 304 alloy, which includes 18–20% chromium, 8–10.5% nickel, and a higher carbon content (0.04–0.10%). This unique blend boosts tensile strength, creep resistance, and heat tolerance while still offering impressive corrosion and oxidation resistance up to 870°C. Typically, the material showcases tensile strength between 515 to 750 MPa, maintaining excellent toughness and ductility even when faced with thermal stress.
