ASO people make it happen

Our History – Healthy Growth

ASO was founded by Aldo Artioli in 1971. The company expanded during the following years to become a successful and internationally operating ASO GROUP. However, we draw our motivation not from our size, but from staying close to our customers.

In fact, the founder’s values run through the company’s history like a golden thread: top quality, strict customer focus and innovations born of our own strength.


The first 10-tonne furnace

The first 10-tonne furnace was installed in 1972. Initially, the company supplied end users with a highly diverse range of ingots, but later it decided to serve mainly forges, paving the way for future development


The new melting furnace

In early 2002 the existing melting furnace was replaced with a new one of a variable capacity of 30–50 tonnes. A second, more modern, vacuum degassing system was built and installed the same year.



The VAR installation

As part of its ongoing process of innovation, ASO installed a vacuum arc remelting (VAR) system in 2007, mainly for steel grades for the aerospace industry. In 2008 ASO installed a 35-tonne induction furnace and a new off-gas extraction system.



In 2011 the ASO Group took over SPS, a company near Verona that produces and processes special and stainless steel grades,and boasts twenty years’ experience in cold-processing round bars with chrome-plating being its main activity.



Acquisition of Cromsteel to become a top player in the market of hydraulic components



Acciai Speciali Ospitaletto – was established in 1971 by Aldo Artioli, a businessman and metallurgical chemistry expert.


The first ladle furnace

1990 saw the installation of the first ladle furnace (LF) and the first vacuum degassing (VD)plant, as a result of ASO’s ongoing commitment to investing heavily in technology and human resources.


The third LF and VD system

A third LF and an adjacent VD system were installed in 2006 to increase ASO’s capacity and guarantee excellent product quality as a result of accurate control of furnace holding times.


ASO Forge

A new facility, called ASO Forge, was founded in 2010 to produce forged bars from ingots made at the steel mill. This new 15,000 m2 facility stands on 25,000 m2 of land in Castegnato (Brescia),very close to the new Brescia–Bergamo–Milan motorway.


The ESR installation

ASO started with a new ESR (electric slag remelting) production.
