Many significant strides have been made over the past quarter century in developing new corrosion-resistant casting alloys such as the super austenitics and super duplex stainless steels, but it is unlikely that such breakthroughs will continue in the future. The reasons for this are many. For example, fewer R&D departments in captive foundries can be supported by the parent company.
Another reason is that independent foundries do not have the resources for R&D, or the money to promote a new alloy. Therefore, any new alloy is more likely to come from the wrought producers than from foundries. Furthermore, the fact that a wrought ...
