ED Stainless stands out as a top-notch manufacturer and supplier of premium stainless steel fasteners, proudly based in Houston, Texas, USA. With a focus on Stainless Steel 304H Nuts, this company has built a reputation for delivering precision-engineered products that not only meet international standards but also cater to the specific needs of various industries. With years of experience under their belt, ED Stainless provides dependable and long-lasting solutions for a diverse array of sectors, including petrochemical, oil & gas, power generation, and construction. By merging cutting-edge manufacturing techniques with strict quality control, ED Stainless guarantees that each Stainless Steel 304H Nut performs exceptionally well and resists corrosion, even in high-temperature and high-stress situations.
The Stainless Steel 304H Nuts produced by ED Stainless are made from a high-carbon version of 304 stainless steel, making them perfect for high-temperature applications. Their typical chemical makeup features 18–20% Chromium, 8–11% Nickel, and a higher carbon content (0.04–0.10%) that enhances strength at elevated temperatures. These nuts boast impressive mechanical properties, including a tensile strength of about 515 MPa, a yield strength of 205 MPa, and an excellent elongation of around 40%. Such characteristics make 304H Nuts ideal for tough environments where mechanical performance and corrosion resistance are crucial, particularly in structural and pressure-containing systems.
