Properties
Resistant to acids with lowering resistance effects with sulfuric acid and hydrochloric acid, it can cause pitting and
stress corrosion.
Good resistance to intercrystalline corrosion up to 400 º C and surface corrosion.
For a best anticorrosive effect it is recommended to polish (mirror.effect)
Easy machining and inlaying.
Steel of greater weldability than Remanit 4401 due to its low carbon percentage.
Applications
In the pharmaceutical industry.
Production of artificial textile fibers and obtain from carbon derivatives.
For tanks, pipes, fittings in the chemical industry, such as paper and pulp mills.
Photography industry, textile dry cleaners of high chemical demand.
Medical and surgical instruments.
Manufacturing of fruit juices, liqueurs and alcohol and where there should be no influence on taste.

Welding
Very good weldability. Classic recommendations for welding 2010NiMo stainless steel.
It is preferably recommended using: BW ELC SS (for joint) and there are other alternatives in TIG and MIG
process. Any queries, please contact the Technical Department of SOLDEX S.A.
