YAOYI technology has transformed the Bright Annealing Furnace line and improved the quality of cold-rolled stainless steel coils

NINGBO, China, August 7, 2021 / PRNewswire / – Yaoyi Stainless Steel, on the southeast coast of China, covers an area of more than 50 hectares and has 25 years of experience in the manufacture of cold-rolled stainless steel coils.

About Yaoyi
Because it specializes in the research and development, production and sales of high-precision stainless steel Stripes for more than two Decades, YAOYI has a very close relationship with its customers, and some customers have been working together for 23 years.

This time, the general manager of Yaoyi spent more than $ 150,000 renovate the bright annealing furnace line, which has significantly improved the elongation, surface and mechanical properties of cold rolled stainless steel coils.

Our products
Yaoyi currently mainly produces cold rolled stainless steel strips such as 201, 301, 304, 304L and 316. It is worth mentioning that the star product 301 stainless steel coils can meet customers’ demands for high hardness and high tensile strength.

Among the 200, 300 and 400 series stainless steels, 301 is the steel most likely to be hardened by cold working and has excellent rust resistance under atmospheric conditions, making it suitable for heavier load, light weight applications and does not rust. Equipment parts. In addition, 301 tends to work hardening in the event of an impact from an external force, as a result of which more impact energy is absorbed and a higher guarantee of safety for the equipment and production personnel is ensured.
