Al Summan Metals, based in Dubai, UAE, has built a strong reputation as a trustworthy manufacturer and supplier of premium **Haynes 188 Bars and Rods**. Known for their accuracy and toughness, Al Summan Metals produces cobalt-based alloy bars and rods engineered to endure extreme high temperatures and corrosive settings. Haynes 188 is especially valued for its exceptional strength, oxidation resistance, and steadiness under severe conditions, making it a preferred option for the aerospace, chemical processing, and power generation industries. Through advanced manufacturing methods and strict quality control, Al Summan Metals ensures that its Haynes 188 Bars and Rods provide reliable, durable, and high-performance solutions for even the toughest industrial applications.
These Haynes 188 Bars and Rods consist mainly of cobalt (approximately 50%), together with nickel (20%), chromium (20%), tungsten (4%), iron, and small quantities of additional elements. This distinctive composition delivers superb mechanical strength, excellent resistance to oxidation and carburization under high temperatures, and impressive creep and fatigue resistance. Mechanically, these bars and rods can reach tensile strength as high as 1,200 MPa, feature high yield strength, and display good elongation, which makes them ideal for high-stress, high-temperature, and corrosive settings.
