GH5188 Haynes 188 Nickel Alloy Pipe UNS R30188 High Temperature Alloy Seamless Tube

GH5188 Tube Haynes 188 Nickel Alloy Pipe UNS R30188 High Temperature Alloy Seamless Tube

Product Introduction

GH5188 Tube is a high-performance cobalt-based high-temperature alloy tube with excellent high-temperature strength and oxidation resistance. This alloy is solid-solution strengthened by adding 14% tungsten, so that it still maintains excellent mechanical properties in high-temperature environments. At the same time, the addition of high content of chromium and trace amount of lanthanum in the alloy further improves its high-temperature oxidation resistance.
GH5188 Tube is widely used in aerospace, energy and chemical industries. In the aerospace field, it is used to manufacture key components of aircraft engines, such as combustion chamber flame tubes and guide vanes. In the energy field, GH5188 Tube is used to manufacture high-temperature components such as combustion chambers and tail nozzles of gas turbines, demonstrating its excellent thermal stability and corrosion resistance. In the chemical industry, it is used to manufacture components such as linings and valves of high-temperature and high-pressure reactors.
