UNS S32053 Stainless Steel

S32053 stainless steel is a superaustenitic (highly alloyed) stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition.

It has a fairly high ductility and a moderately high thermal conductivity among wrought superaustenitic stainless steels.

The graph bars on the material properties cards below compare S32053 stainless steel to: wrought superaustenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition

Among wrought stainless steels, the composition of S32053 stainless steel is notable for containing comparatively high amounts of chromium (Cr) and nickel (Ni). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance. Nickel is primarily used to achieve a specific microstructure. In addition, it has a beneficial effect on mechanical properties and certain types of corrosion.

Iron (Fe) 41.7 to 48.8
Nickel (Ni) 24 to 26
Chromium (Cr) 22 to 24
Molybdenum (Mo) 5.0 to 6.0
Manganese (Mn) 0 to 1.0
Silicon (Si) 0 to 1.0
Nitrogen (N) 0.17 to 0.22
Carbon (C) 0 to 0.030
Phosphorus (P) 0 to 0.030
Sulfur (S) 0 to 0.010
