Wujin Stainless  has organized and participated in the formulation and revision of 18 national and industrial standards. It has 67 patents in force, including22 invention patents and 45utility model patents, which covers the entire process of product manufacturing and inspection, and shows the independent intellectual property rights of the products of Wujin Stainless .


Since there had been no stainless steel seamless pipes for boilers of ultra-supercritical thermal power units in China, Wujin Stainless Steel has made independent innovation, and formed core technologies and products with independent intellectual property rights. It has successively passed the scientific and technological achievements appraisal of China Machinery Industry Federation, China Standardization Committee on Boilers and Pressure Vessels, and Chinese Society for Electrical Engineering. The products have reached the advanced level compared with similar products in foreign countries, substituting imported goods and filling domestic gaps. Other technical advantages include: one-time large deformation cold rolling technology for large-caliber thick-walled seamless pipes. Through large-deformation cold rolling, the internal grains of steel pipes are refined to make the product have a uniform grain size.
