Heat Treatment in High Chromium White Cast Iron Ti Alloy

The influence of heat treatment on microstructure and mechanical properties of high chromium white cast iron alloyed with titanium was investigated. The austenitizing temperatures of 980°C and 1150°C for 1 hour each followed by tempering at 260°C for 2 hours have been performed and the effect of these treatments on wear resistance/impact toughness combination is reported.

Machining and Heat Treating ASTM A-532

Jul 19, 2011 · Does anyone have any experience working with ASTM A-532 25% high chrome iron? These are cast parts. A-532 Grade III is about Rc42/400 BHN at pour...and can be annealed down to 300 BHN and machined. It can then be heat treated to 600+ BHN. Some pump mfgs, such as Weir-Wemco, use this for grit ...

Effect of Heat Treatment on Microstructure and Mechanical ...

wear performance of high chromium white cast iron. Quenching, seeding and micro-alloying can, to a limited extent, increase the wear resistance, but this is best achieved by heat treatment in the solid state. The methods for producing high chrome iron casting include double pour, continuous pour and centrifugal castings [1, 3].
