Kubota has developed the KHR MA7 as economic alloy using microalloying
technology which can reduce the Ni content with the same creep rupture
strength as microalloyed KHR35CT (25Cr-35Ni-Nb,Ti). It is primarily used in
reformer furnaces where its high strength can be used to reduce wall thickness
and tube weight while increasing catalyst capacity. The alloy is suitable for
long term service at temperatures up to 1050C (1922F).
