Material Notes:
P/M 625M (chemically, UNS N07626) is produced by the state-of-the-art Crucible P/M process: inert gas atomization, coupled with consolidation by hot isostatic pressing (HIP) and/or extrusion. The advanced Crucible powder consolidation operation guarantees a fully dense, fine grained product. Crucible custom crafted parts can be produced with shorter lead times and less user costs than comparable conventional alloys.Crucible P/M 625M is a patented composition designed to take advantage of the aging response associated with rapid solidification rate powder metallurgy technology. Those elements (Al, Cb, and Ti) which effect the precipitation reactions have been optimized to achieve yield strengths above 120 ksi. The rest of the composition has been balanced to maintain good corrosion resistance. P/M 625M offers both a high strength level, like that of alloy 718, and good corrosion resistance, like that of Crucible P/M 625, in one alloy. Engineers and designers no longer have to choose one or the other. Since Crucible produces this alloy by powder metal techniques, lower total costs are a reality. If material is purchased as a near net shape or a clad product, less weight has to be bought. This makes fabrication easier and significantly lowers over manufacturing cost.Advantages:Near new shapes Fastener material Excellent corrosion resistance Excellent strengthFlexibility in design NACE MR-01-75 approvedInformation provided by Crucible Compaction Metals.
