Known for their precision engineering and durable fastening solutions, Ed Stainless caters to various industries throughout Texas and the United States, always prioritizing excellence and customer satisfaction. Their Stainless Steel 321 / 321H Stud Bolts are celebrated for their outstanding corrosion resistance, high-temperature strength, and reliability under pressure. Ed Stainless guarantees that every product adheres to international standards, meeting the rigorous demands of the petrochemical, oil and gas, power generation, and aerospace sectors with unparalleled quality and service.
In Texas, USA, Ed Stainless produces Stainless Steel 321 / 321H Stud Bolts using stabilized austenitic steel with titanium (Ti) to enhance intergranular corrosion resistance. The typical chemical makeup features Chromium (17–19%), Nickel (9–12%), and Titanium (≥5x C%). The mechanical properties include a minimum tensile strength of 515 MPa, a minimum yield strength of 205 MPa, and excellent creep resistance. The Type 321H, which has a higher carbon content, provides improved high-temperature strength. These characteristics make the stud bolts perfect for use in high-temperature environments, capable of withstanding temperatures up to 900°C (1650°F).
