That looks to be a plate steel stove with cast iron doors. The dead giveaway is the welds . Cast iron isn't routinely welded. Looks like a fisher clone with hot water jacket and possibly a hot water coil. I seriously doubt its any sort of special alloy realizing that all steel is an alloy. Expect its just low grade boiler plate. I have seen a couple of homemade versions over the years. They work well as long as there is circulation through the jackets and properly located safety reliefs on the piping.. They can be a bomb if they are full of water and allowed to boil with valves closed (like any boiler).
