La prima colata di Ferro Puro ARMCO® prodotto in Europa fu prodotta in Germania dalla Vereinigte Stahlwerke AG (oggi ThyssenKrupp Steel). Nel 1957 venne sviluppato il Telar 57 ARMCO® come variante anti-invecchiamento del Ferro Puro ARMCO®, per soddisfare necessità specifiche dell’industria elettrotecnica. After more than 90 years, ARMCO ® Pure Iron , thanks to its peculiar characteristics, is still a very modern product, which satisfies the needs of the most modern and advanced industrial sectors. Its unique features and numerous applications ranging from remelting to electromagnetic components, and the various forms in which it is available, from remelting billets to pyrometer protection tubes, are described on the following pages. AVAILABLE PRODUCTS Features Chemical analysis Applications Sections Available Features ARMCO ® Pure Iron : the purest iron ever produced, Fe = 99.85% homogeneous structure of pure ferrite containing exceptionally low levels of carbon, oxygen and nitrogen, and a minimal presence of non-metallic inclusions. Compared to mild steels, the high degree of purity offers significant advantages: better resistance to corrosion, oxidation and chemical attack. excellent electrical and magnetic properties excellent properties for cold working excellent weldability Telar 57 ARMCO ® : Magnetic soft iron with excellent anti-aging properties (similar to Rfe 40 - 140 according to DIN 17045) high magnetic flux density low coercive force Chemical analysis ARMCO ® Pure Iron Grade 1 * Grade 2 Grade 3 * Grade 4 % max. max. max. max.
