OREANDA-NEWS. December 20, 2011. TISCO pure ferritic stainless steel monthly sale exceed 9,000 tons for the first time. This historical breakthrough marks that TISCO stainless steel varieties development, manufacture process, technical management, product quality and other aspects have reached to a new level, which creating a new start in the domestic stainless steel industry, reported the press-centre of TISCO. 

In recent years, the tight supply of global resources, increasing high prices in non-ferrous metal market, especially the frequent fluctuation of nickel price, have brought great cost pressure to stainless steel production enterprises. Ni-based stainless steel price goes high according to the sharp increase of nickel price, therefore, some originally austenitic stainless steel users have to seek materials with lower price, and this limits the potential user needs of stainless steel. These factors contribute to the rapid development of ferritic stainless steel in recent years.

With low cost, stable price and many unique features and advantages, ferritic stainless steel can replace austenitic stainless steel in many areas. Because of there are some other alloy elements (molybdenum, titanium, niobium, etc) was added in the super pure ferritic stainless steel with (C + N) ? 0.01% during the production, it not only has most mechanical properties and corrosion resistance like expensive austenitic stainless steel, but some performance is superior to the austenitic, especially has outstanding performance in formability, corrosion resistance and oxidation resistance on. Ultra pure stainless steel win widely favor by its superior mechanics and corrosion resistant comprehensive performance, has become a kind of good corrosion resistant industrial material that save not only material but also cost.

Stated research of super pure ferritic stainless steel from the 1990s, TISCO has successfully developed steel grades like 436L, 441, 429, 439, 439M, 443, YH21CT, 444 and other varieties with independent intellectual property rights, formed the varieties and specifications of super pure ferritic stainless steel series products, and filled the domestic blank. At present, the series of varieties are mainly applied in automobile exhaust system, hardware products, solar energy, decoration, water tank industry and so on, being the first in the domestic market share for five consecutive years.
