ALLOY 255 is a 25% chromium duplex ferritic-austenitic stainless steel designed to provide a superior combination of high strength and excellent corrosion resistance for a wide variety of applications.
We could delivery ALLOY 255 forging material as per the standard of A-182
We use EAF+VOD-ESR melting methods to melt the material of ALLOY 255
ALLOY 255 displays superior corrosion resistance in most media. Also, F61 typically out performs duplex alloy 2205. Alloy F255 performs well in sulfuric, phosphoric, nitric and shows excellent resistance to organic acids such as acetic and formic acid. Highly reducing media should be avoided.

ALLOY 255 should be stypically solutionannealed at between 1950°F and 2050°F,followed by rapid
cooling to prevent precipitation of deleterious sigmaphase and reduction in toughness.
ALLOY 255 could be machined using techniques&equipment similar to 300 series stainless
