Description of material
AN5 is a high Nickel–Chromium–Molybdenum-Titanium and Aluminum precipitation hardening austenitic stainless steel with good general corrosion resistance as well as oxidation resistance at high temperatures. This grade has been designed in order to offer a good cold deforming and cold head ability thanks to an exact chemical balance and high level of strength both at room temperature and at high temperatures after solution treatment and aging heat treatment.
Applications
AN5 is suitable for the fabrication of many products such as bolting/fasteners in automotive engines, gas turbines, nozzles, exhaust parts and in any kind of device where a high temperature resistance and creep resistance are indispensable requirements.
