Incoloy909 Hex Flange Bolts
Incoloy909 hex flange bolts are engineered for high-temperature, high-stress environments where exceptional strength, oxidation resistance, and dimensional stability are critical. These specialty fasteners are widely used in the aerospace, marine, and power generation sectors due to their advanced alloy composition and reliability under extreme conditions. Developed from proprietary Incoloy 909 alloy, they boast superb mechanical properties and corrosion resistance, making them ideal for critical applications.
Product Overview
Incoloy909 hex flange bolts are high-strength, corrosion-resistant fasteners manufactured from a nickel-iron-cobalt-based superalloy. Designed specifically for excellent thermal stability and low coefficient of expansion, these bolts are commonly used in gas turbines, jet engines, and nuclear systems. Featuring an integrated flange beneath the bolt head, they distribute the clamping load more evenly and eliminate the need for separate washers, increasing efficiency and strength.
