Super Duplex
The grade UNS S32205 (1.4462, F51) is the most commonly specified duplex stainless steel.
There is a considerable improvement in the mechanical and physical properties of super duplex stainless steel vs 316.
Super duplex is ‘shorthand’ for a family of high-performance stainless steels based around a 25% chromium content. Learn more by visiting Langley Alloys today!
S21800 is the Unified Numbering System (UNS) designation for a more highly alloyed stainless steel most commonly known as Nitronic 60.
S20910 is the Unified Numbering System (UNS) designation for a more highly alloyed stainless steel most commonly known as Nitronic 50.
1.3964 is the Werkstoff number for a more highly alloyed austenitic stainless steel most commonly known as Nitronic 50.
1.4501 is the Werkstoff number for a super duplex stainless steel most commonly known as Zeron 100 or UNS S32760.
XM19 is an alternative description for a more highly alloyed austenitic stainless steel most commonly known as Nitronic 50.
1.4507 is the Werkstoff number for a super duplex stainless steel most commonly known as Ferralium 255.
A super austenitic stainless steel is considered to be one with a Pitting Resistance Equivalent Number (PREN) greater than 40.
It is possible to expose austenitic stainless steels to different heat treatments, but there is no increase in strength.
The internal microstructure of austenitic stainless steels is not influenced by an external magnet, and is non-magnetic.
