Description

Alloy MA20 is used: for the manufacture of semi-finished products (sheets, plates, bars, rods, profiles, strips, tubes, wire, stampings and forgings) by hot deformation, as well as ingots and slabs intended for the production of welded details with complex geometric shapes, long-working temperature up to +150 °C and for short periods up to +200 °C.

Note

Alloy brand MA20 has medium strength, high ductility, good weldability and corrosion resistance, is not prone to stress corrosion cracking.
