carbon, manganese and other alloy steels
Specialists in the moulding and machining of large parts in short series in carbon, manganese and other alloy steels.
CARBON STEEL
Our experience and knowledge of the special characteristics of carbon steel allow us to undertake the moulding and machining of highly complex parts, such as some electric motor housings, ampoules or dies.
Other common carbon steel parts are railway material and equipment (bogies, axle boxes, etc.), parts for the iron and steel industry and the manufacture of capital goods.
MANGANESE STEEL
Manganese steels, also known as austenitic steels or Hadfield steels, are non-magnetic and non-conductive steels, with an initial hardness of 190 HB ± 25. These steels harden on cold impact up to values of 500 HB, which makes them very suitable for parts that require high resistance to wear and material fatigue.
Such as track switch cores, in which Amurrio is a recognised international leader.
Other common applications for austenitic steels are jaws, bars or cones and bollards, as well as parts for desalination plants, quarries, cement works or mining.
OTHER ALLOYS
We mould parts in any type of alloy steel according to customer specifications, such as parts for dies, housings, shipbuilding, mining, cement, etc.
