Edward Waddell co-founded MTS Forge in 1986 alongside Stephen Carr, bringing a metallurgical background and comprehensive knowledge of forging practices to the partnership. Together, they grew the company on a commitment to quality, service, and innovation — values that continue to define MTS Forge's operations today. Edward's deep understanding of forging materials and processes has driven the company's ability to serve highly regulated industries including commercial nuclear, aerospace, and defense, where precision, traceability, and mechanical reliability are non-negotiable. His leadership has helped MTS Forge expand its product range — including alloy steel pipe flanges, special forgings, and custom components — and maintain its reputation for excellence across its customer base in Pennsylvania, Iowa, Kentucky, Texas, and beyond.
Alloy flanges are pipe flanges manufactured from steel alloys that contain additional elements — such as chromium, molybdenum, nickel, or manganese — beyond the base carbon content. These alloying elements enhance mechanical properties like tensile strength, toughness, hardness, and corrosion resistance. Common alloy steel grades used for flanges include ASTM A182 F11, F22, and F91, each suited to high-temperature or high-pressure service conditions in power generation, chemical processing, and similar industries.
