In key equipment such as high-temperature cracking furnaces and conversion furnaces in the petrochemical industry, the furnace tubes are subjected to severe tests including high temperatures, high pressures, and corrosive atmospheres for an extended period. 309 stainless steel plate, with its excellent high-temperature strength and anti-carburization ability, has become the ideal material choice for such components.
Its high chromium and nickel content ensures stable oxidation resistance at working temperatures above 900℃, effectively reducing the material's wear rate during long-term high-temperature service. Practical cases have shown that the furnace tubes made of 309 stainless steel can significantly extend the maintenance cycle in ethylene cracking plants, reducing unplanned shutdowns caused by oxidation flaking and carbonitriding embrittlement, and achieving significant overall economic benefits.
Jiangsu Cunrui Metal Products Co., Ltd. has provided 309 stainless steel plates that meet strict standards to several petrochemical enterprises. The stable product quality of the company has helped its customers achieve long-term safe operation of the facilities.
