--The preferred choice for extreme high-temperature environments
In the demanding conditions of continuous extreme high temperatures, 309 stainless steel plate, with its outstanding anti-oxidation and anti-thermal fatigue properties, becomes a reliable material solution.
Its high chromium (Cr) content (approximately 23%) ensures that a dense and highly adherent chromium oxide protective layer can form on the material's surface at intermittent temperatures up to 1150℃, effectively blocking oxygen and preventing material loss due to continuous oxidation. At the same time, the optimized nickel (Ni) content and stable austenitic structure give it excellent resistance to thermal fatigue - that is, in repeated heating and cooling cycles, the material can resist the initiation and expansion of micro-cracks caused by thermal stress, thus maintaining long-term structural integrity in industrial furnaces, heat treatment equipment, and other environments with frequent thermal cycling.
Jiangsu Cunrui Metal Products Co., Ltd. specializes in supplying high-quality 309 stainless steel plates. Its stable performance ensures the reliable operation of equipment in extremely high-temperature environments.
