Broder Metals supply three variants of F55, including two enhanced metals known as FLT and FLT+, which have been charpy tested at various cryogenic temperatures, for your customer need. The differences in the three variants are very small, and are reflected minorly in yield and decreased sensitivity to brittleness in a temperature drop.
