With years of experience under their belt, Ed Stainless has built a solid reputation for providing precision-engineered fasteners that adhere to strict industry standards. They specialize in products that are both corrosion-resistant and capable of handling high temperatures, offering a range of items like bolts, nuts, washers, and studs that are designed to endure extreme conditions. With a strong focus on quality, timely delivery, and customer satisfaction, Ed Stainless caters to a wide array of clients in sectors such as oil & gas, petrochemical, power generation, and marine industries throughout Texas and beyond.
The Stainless Steel 321 / 321H Fasteners from Ed Stainless are primarily made up of chromium (17-19%), nickel (9-12%), and titanium, which helps stabilize the alloy against chromium carbide precipitation. The 321H variant features a higher carbon content, boosting its strength at elevated temperatures. These fasteners are known for their excellent oxidation resistance, creep strength, and good weldability. Their mechanical properties include a tensile strength of about 75 ksi (515 MPa), yield strength of 30 ksi (205 MPa), and an elongation of 40%. This makes them perfect for high-temperature, corrosive environments where durability and mechanical performance are crucial.
