STAINLESS STEEL

Acesita steel plant in Timoteo - Brazil

Acesita was founded on October 31st, 1944 by engineers Amyntas Jacques de

Moraes, Percival Farqhuar and Athos Lemos Rache, and operations started in April

1949, with the purpose of producing special steels to supply the local market. Since

startup, several expansion programs have been implemented aiming at introducing

state-of-the-art technology for the manufacture of steels applied to the steel industry.

Through that, the company has faced a continuous growth up to the present date.

The production of 850,000 t/year of raw steel makes Acesita to stand out in the world

scenario due to its high technological content and product quality.

Its line of products also includes stainless flat steels and grain-oriented and non-

oriented silicon steels and special carbon steels, of which it is the only South American

manufacturer.
