What is AISI 304H stainless steel angle?
AISI 304H stainless steel angle is a high-carbon variant of 304 stainless steel, offering excellent high-temperature strength and oxidation resistance. The "H" in 304H indicates a higher carbon content (0.04-0.10%), which improves creep strength and structural stability at high temperatures. Compared to standard 304, 304H exhibits higher creep strength and better long-term stability at temperatures above 500°C. This makes it a preferred choice for industrial furnaces, heat exchangers, pressure vessels, and boilers.
GNEE supplies AISI 304H stainless steel angle bars, an improved austenitic chromium-nickel stainless steel formed through hot rolling or forging processes and subjected to solution annealing treatment. While maintaining the excellent corrosion resistance of standard 304 steel, it significantly enhances high-temperature strength and creep resistance (with a long-term service temperature of up to 800°C and short-term tolerance of 900°C), making it particularly suitable for structural support and load-bearing components in high-temperature environments, such as boiler frameworks, heat exchanger supports, high-temperature pipe mounting angles, and industrial furnace connections.
Our 304H stainless steel angle bars feature leg dimensions ranging from 20×20 mm to 200×200 mm (custom non-standard sizes available) and thicknesses of 3.0–20.0 mm (standard angle thicknesses adapted to structural strength requirements). The surface is smooth, free from cracks or folds, with rounded edges (R≥2mm) to enhance assembly safety and welding adaptability.
