F22, F91, F92 Steel Round bar

Yep.........John Galt Steel powered by U.S.Alloys can supply Grade F22 containing 2.25% of chrome, which can be suitable for up to 1100°F (590°C), F91 with 9% chrome can withstand temperatures up to 1200°F (650°C), and our newest grade is F92.

Our F92 bar stock which valve manufacturers make a F92 Class 2500 valve at 1112°F (600°C) delivers a special class rating of 223.4 bar compared with 203.1 bar for F91. At 1067°F (575°C) the ratings are the same for both F91 and F92. However at 1157°F (625°C) the difference is 190.6 bar for F92 compared with 152.1 for F91.
