Ningbo Qihong Stainless Steel Co., Ltd. has been deeply involved in precision stainless steel processing and manufacturing for many years. Leveraging advanced equipment and mature processes, we offer high-quality tempered stainless steel strips, providing reliable material solutions for high-end manufacturing industries.Compared to ordinary cold-rolled 2B surfaces, bright finish stainless steel foil combines the corrosion resistance and high strength characteristics of stainless steel with an excellent appearance. The surface is free of oxidation, has low roughness, and high cleanliness, allowing for direct use without additional pickling and passivation; it utilizes mature steel grades such as 304, 301, and 430, adapting to the needs of high-end manufacturing in multiple fields.

Ningbo Qihong Stainless Steel has been deeply involved in the supply of precision stainless steel materials for many years. Its high quality bright finish stainless steel foil is recognized by various industries for its stable process and reliable quality. The product undergoes bright annealing or precision grinding and polishing, resulting in a uniform, high-gloss, silvery-white surface. It is an ultra-thin strip material ranging from 0.02-0.05mm, belonging to the category of high-value-added precision metal materials.

As a professional stainless steel material supplier, Qihong's 301 stainless steel foil is meticulously crafted through a precision cold rolling process, with a thickness range of 0.02-0.3mm. Among them, the ultra-thin specifications can reach the "tearable steel" level, making it a core material for lightweight and miniaturized designs in the high-end manufacturing field. It has gained widespread recognition and favor from customers in various industries over the years.

Ningbo Qihong Stainless Steel Co., Ltd. has been focusing on the processing and manufacturing of precision stainless steel strips, plates, and precision fasteners for many years. We have developed the high quality 321 stainless steel foil. Made from 321 austenitic stainless steel, it is processed through a series of fine processes including cold rolling, annealing, and surface treatment. With a thickness between 0.01mm and 0.1mm, it is reliable for use in various applications, including aerospace, chemical, and energy fields, as well as electronic heating elements and high-temperature equipment manufacturing.
