We pride ourselves on delivering reliable fastening solutions for a wide range of industrial and commercial needs. Our Stainless Steel 304H Nuts stand out for their impressive strength, outstanding corrosion resistance, and ability to perform well under high temperatures. Crafted with cutting-edge equipment and rigorous quality control, these nuts are built to last and deliver consistent performance even in tough conditions. At Akor Stainless, we’re committed to meeting our customers’ needs with prompt delivery, competitive pricing, and expert technical support. Our products are highly regarded in various sectors, including construction, petrochemical, power generation, refinery maintenance, and mechanical engineering.
These Stainless Steel 304H Nuts are made up of chromium (18–20%) and nickel (8–11%), featuring a higher carbon content compared to the 304 or 304L grades, which boosts their strength at elevated temperatures. They offer a tensile strength of around 515 MPa while maintaining excellent toughness and stability under thermal stress. The added carbon content enhances their creep resistance and overall structural integrity. With reliable corrosion resistance in both oxidizing and mildly corrosive environments, these nuts are perfect for high-temperature and heavy-duty fastening tasks.
