What is SAF32760?

SAF32760 is a registered trademark of Alleima. SAF is an acronym of Sandvik Austenitic Ferritic, with Austenitic Ferritic meaning it’s a super duplex stainless steel grade with a balanced microstructure. This balanced microstructure imparts the favourable properties of super duplex stainless steels, namely high-strength, excellent corrosion resistance and good impact properties. It contains a slightly higher copper and tungsten content, compared with S32750.

The History of SAF32760

SAFS32760 (UNS S32760, DIN 1.4501, ASTM F55) was originally developed as Zeron 100 by the UK company Mather & Platt in the 1970s. Mather & Platt was a UK-based company, hailing from Manchester, focused on the manufacturing of large-scale centrifugal pumps. The use of super duplex stainless steels for such applications was obvious, given the potentially aggressive solutions being handled, requiring significant corrosion resistance, strength and wear resistance. Hence, the team at Mather & Platt sought to optimise ease of casting and long-term performance of their pump bodies for more demanding applications. The pump division of Mather & Platt was subsequently acquired by Weir Pumps, although the Manchester site and foundry closed. The Zeron 100 trademark is now held by Rolled Alloys Inc.
