1. Nickel-Based Alloy Introduction
The Incoloy alloy family comprises nickel-based, corrosion-resistant alloys with an iron-chromium backbone. These alloys excel in resisting corrosion in both reducing and oxidizing acids, along with demonstrating resilience against stress corrosion cracking, pitting, and crevice corrosion. Among the commonly utilized grades in chemistry, petrochemicals, nuclear industry, and rare metal extraction are incoloy800, incoloy825, and incoloy926.
The Inconel alloy series is renowned for its nickel-chromium-iron composition, which offers unparalleled high-temperature corrosion and oxidation resistance. Additionally, it boasts exceptional cold and hot processing capabilities and welding performance. This alloy finds widespread application in the aviation, chemical, paper industry, and other domains. Popular grades include inconel600, inconel601, inconel625, inconel617, inconel718, and inconelx750.
The Hastelloy alloy group is a nickel-based alloy that is both corrosion-resistant and suitable for high-temperature applications. It primarily falls into two categories: nickel-chromium and nickel-chromium-molybdenum alloys. These alloys possess robust corrosion resistance and thermal stability, making them ideal for use in aviation, petrochemical, and chemical industries. Common grades include Hastelloy C276, Hastelloy C22, Hastelloy B2, Hastelloy B3, Hastelloy C4, Haynes 230, and Haynes 188.
2. Inconel 718 Pipe Fittings
The Inconel 718 material exhibits outstanding comprehensive performance within the temperature range of -253 to 700 ℃. Its yield strength below 650 ℃ stands at the forefront among deformed high-temperature alloys. This alloy also boasts excellent fatigue, radiation, oxidation, and corrosion resistance, along with superb processing, welding performance, and long-term structural stability. Its ability to fabricate intricate components has led to widespread adoption in the aerospace, nuclear energy, and petroleum industries within the aforementioned temperature range.
