Ed Stainless is a top-notch manufacturer and supplier of high-quality Stainless Steel 347H Fasteners, proudly based in Houston, Texas, USA. Renowned for their outstanding durability and ability to withstand high temperatures, Ed Stainless fasteners are designed to meet the strictest industry standards for critical applications. The company focuses on crafting bolts, nuts, washers, studs, and various other fasteners from 347H stainless steel—an austenitic chromium steel alloy that’s stabilized with columbium (niobium). With a strong dedication to precision engineering, timely deliveries, and ensuring customer satisfaction, Ed Stainless caters to a diverse array of industries, including petrochemical, aerospace, power generation, and marine, both in the USA and around the globe.
The Stainless Steel 347H Fasteners from Ed Stainless are made from a high carbon variant of Type 347, providing excellent creep strength and corrosion resistance even at elevated temperatures. Their typical chemical makeup includes Chromium (17–19%), Nickel (9–13%), and Columbium (10xC–1.10%), along with trace elements like Manganese, Silicon, and Phosphorus. In terms of mechanical properties, these fasteners boast a minimum tensile strength of 515 MPa, a yield strength of 205 MPa, and an elongation of 35%. These impressive mechanical characteristics make them perfect for high-temperature pressure systems and environments that experience thermal cycling.
