304H

304H stainless steel (UNS S30409, 1.4948) is a high‑carbon austenitic stainless steel variant of standard 304 grade, with controlled carbon content between 0.04% and 0.10%. It features outstanding high‑temperature strength and creep resistance, retaining reliable mechanical performance under long‑term elevated temperature service. It maintains good oxidation resistance and weldability for boiler, heat exchanger and pressure vessel applications. Detect Metals supplies a full range of 304H stainless steel semi‑finished materials for high‑temperature industrial projects.
