SAF™ 3006 is a high-alloy duplex stainless steel tailored to enhance corrosion resistance in acidic and caustic environments. The new alloy, an upgrade to traditional super-duplex stainless steels, adds to the company’s growing duplex portfolio. The main application is heat exchangers in the chemical and petrochemicals industries.
Alleima is a global manufacturer of high value-added products in advanced stainless steels and special alloys. Since the 1960s, the company has been at the forefront of developing modern duplex grades and now offers a broad portfolio.
“We’re thrilled to welcome this new super duplex to our expanding duplex family. It provides that ‘missing duplex tool’ for customers battling acids in heat exchangers, giving them that extra edge. With the addition of SAF™ 3006 (UNS S83071), we strengthen our presence in duplex materials tailored for acidic corrosion, where we see strong growth potential. Applications may include caustic evaporators, acid coolers and evaporators,” says Eduardo Perea, Market & Product Manager EMEA at Alleima Tube Division.
Alleima pioneered the ‘duplex revolution’ of the 1960s and 1970s, introducing a cost-efficient stainless-steel alternative to more expensive nickel alloy grades. The company continues to innovate in this area. Duplex grades, with a 50-50 austenitic-ferritic structure, offer more than twice the strength of standard stainless steels and superior corrosion resistance.
The groundbreaking SAF™ 2507 (UNS S32750), introduced by Alleima almost four decades ago in 1985, set the industry standard for combatting wet corrosion in a diverse range of industrial applications. Renowned for its exceptional performance in corrosive conditions, SAF™ 2507 offers excellent resistance to stress corrosion cracking (SCC) in chloride-bearing environments, as well as to pitting and crevice corrosion.
