What is full form of EN 24 material?, What is EN 24 equivalent to?, Is EN 24 medium carbon steel?
It’s a medium carbon steel having composition as shown in figure below.
EN 24 is not a stainless steel because the chromium percent is less than 10
. It is a medium carbon steel since EN 24 consists of 0.4% carbon. EN 24 have good tensile strength due to adequate carbon presence but poor toughness. To get toughness, FCC (Face Centered Cubic) element i.e., Nickel is added as an alloying element. Nickel refines the grain size by blocking the grains from becoming larger and coarser during heating. Fine grains have higher toughness as compared to coarser grains. EN 24 is heat treatable and its hardenability is enhanced by adding Chromium as an alloying element. Manganese is used to remove impurities like oxygen and sulphur from the iron ore hence trace amounts will be left over in the final metal.
