Stainless steel 347 Nuts are made of austenitic stainless steel designed to resist high temperatures. The alloy consists of chromium (17-19%) and nickel (9-13%), with the addition of columbium (10 times the carbon content) to stabilize and prevent high-temperature carbide precipitation This makes the nuts 347 suitable for high-temperature environments such as aerospace, chemical processing. They are also ideal for use in the electrical industry, where durability and efficiency are essential.
