Alloys and materials
Standards, classes and certificates according to the approved specification of each project.
Carbon steel
General use in piping, structures and equipment, in services without special corrosion-resistance requirements.
Low-temperature carbon steel
For low-temperature service, where the material must retain toughness.
Stainless steel
Corrosion resistance across a wide range of applications, with grades such as 304 and 316.
Duplex
A two-phase structure with higher mechanical strength and good resistance to chloride stress corrosion cracking.
Super duplex
A version with even higher corrosion resistance, for more aggressive environments such as seawater.
Copper-nickel (CuNi) and Phosphorus copper
Copper and nickel alloys, used in seawater systems, and copper with a phosphorus addition, according to the approved project specification.
Inconel
Nickel alloys for high temperatures and aggressive media.
Special alloys
Other alloys on request. Send the specification and our team will assess the supply.
Which alloy to use?
The alloy comes from the approved project specification, which considers the fluid, temperature, pressure and environment. When the requisition raises questions, our technical team reviews it and points out what needs to be clarified before supply.
