Description:

Resistant — precision alloy based on iron (Fe) (65-82 %), which is composed of chromium (Cr) (12-27 %), aluminium (Al) (3,5-5,5 %), silicon (Si) (1 %), manganese (Mn) (0,7 %).

Used for the manufacture of various heating elements of household appliances and powerful electric heating devices industrial and process furnaces with operating temperatures up to 1400 °C, starting-brake resistors, electric locomotives, railcar rolling stock.

 


Properties:

– very fragile

has a high hardness 200-250 HB on the Rockwell scale. The hardness is comparable to mild steel,

– easily machined

has a high specific electrical resistance of 1.2 and 1.3 μω·m, which determines its application as electric heaters,

density 7100-7300 kg/m3,

melting point of approximately 1450-1500 °C,

– resistant to oxidation in air at high temperature,

has a high yield strength,

– maintains corrosion resistance in various environments, including in an oxidizing atmosphere containing sulfur and sulfur compounds, carbon, hydrogen,

magnetic due to the content in the alloy of iron,

– has a high heat resistance, operating temperature up to 1400 °C.
