Grade TTS443M Super-ferritic stainless steel


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.

Welding Properties and Notice:

  • Low carbon and Nitrigon, Titanium and Niobium added, high corrosion-resisted performance on welding parts.
  • Difficult for Fusion wedding and etter for filler wire welding.
  • Low thermal expansion coefficient-high heat conduction and small deformation after welding comparing with 304.
  • Try to avoid heat imputing, otherwise result in bigger crystalline grain and influent the toughness of the plate.
  • Gas protection: Argon protection is needed to avoid surface oxidization and nitrizing.
  • To Avoid the contanmination of grease, otherwise carburization will occur.
  • Better to use 309L or higher grade welding rod.

Research and Development Target


400 series will be our research and developing target in future. Supper ferritic stainless steel will be hightlight, and as the substitute of 304 for our aim on the direction of economic research and developing. Realize 439 and 443 product seriation, enlarge the application of decorationg industry such ad the decoration of outside roof and curtain wall. Develop the high-chromium ferritic stainless steel such as 445, 446M and so on to improve the application of 400 series.
