Technical advantages:
Producing advantage: Equipped with large-scale, advanced and high efficient equipments, we can produce a series of super ferritic stainless steel product is in different grades and specifications, and meet the requirements of market.
Quality of products: The process which use hot metal as main part of materials to produce super ferritic stainless steel can reduce the unnecessary elements to lowest level. Using VOD decarburization and denitrifying process can get the lower content of carbon and nitrogen.

Application of Super Ferritic Stainless Steel Industry

The industry of automobile exhausting system: We have established long term cooperation with end users and service centers which work at automobile exhausting tubes and pressed parts.
