304H Stainless Steel is often used as a material of construction up to about 1500oF.

304H Stainless Steel (S30409) is a modification of the most widely utilized “18-8” chromium nickel austenitic stainless steel. The carbon content is controlled in the range of 0.04–0.10% for increased strength at temperatures above 800°F (427°C). It is an economical and versatile corrosion resistant alloy suitable for a wide range of general purpose applications. Type 304H is non-magnetic in the annealed condition but may become slightly magnetic as a result of cold working or welding.
