(1) The corrosion resistance and corrosion resistance are similar to 1Cr13 (410) and better, in low concentration of mild organic and [SCALE STEEL]inorganic acid, alkali and some chemical conditions have corrosion resistance.
(2) Good oxidation resistance, sustainable use in 705℃ environment.
(3) good plastic toughness, easy to be formed by rotation, bending and rolling.
(4) It can be welded by common fusion and resistance technology.
The main product form [SCALE STEEL]is plate, used for structural parts such as automobile muffler and exhaust system components, but also widely used in containers, heat exchangers, underground pipes, etc.
