ASTM A182 Grade F10 (S33100) Steel

ASTM A182 grade F10 is an alloy steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. F10 is the ASTM designation for this material. S33100 is the UNS number.

It has the highest base cost among wrought alloy steels in the same category. In addition, it has the highest electrical conductivity and a very high ductility.

The graph bars on the material properties cards below compare ASTM A182 grade F10 to: wrought alloy steels in the same category (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 alloy steels, the composition of ASTM A182 grade F10 is notable for containing comparatively high amounts of silicon (Si) and chromium (Cr). Silicon content is typically governed by metallurgical processing concerns, and not its effects on final material properties. However, it does have a modest strengthening effect. Chromium is used to improve corrosion resistance and most mechanical properties (particularly at higher temperatures).

Iron (Fe) 66.5 to 72.4
Nickel (Ni) 19 to 22
Chromium (Cr) 7.0 to 9.0
Silicon (Si) 1.0 to 1.4
Manganese (Mn) 0.5 to 0.8
Carbon (C) 0.1 to 0.2
Phosphorus (P) 0 to 0.040
Sulfur (S) 0 to 0.030
