Product Description
Alloy steel F92 and P92 scrap (UNS K92460 / 9Cr-2W-Mo steel) consists of advanced, high-chromium ferritic-martensitic alloy steel generated from power generation plants, supercritical boilers, high-pressure steam headers, forged valves, and heavy-wall seamless piping. This specialized scrap grade is designated as tungsten scrap in high-temperature alloy recycling due to its deliberate inclusion of approximately 1.5 to 2.0 percent tungsten for high creep strength.
