Highchromium irons have good mechanical properties, high hardness in a cast state, low fluctuation of hardness when properties change. Highchromium irons almost don''t concede in fluidity to regular gray cast iron that allows using parts sufficiently difficult form directly after casting without the following machining.
Jan 26, 2016· Pliant25 ASTM A532 Class III Type A. Pliant25 is a unique high chrome white iron that has been perfected by Penticton Foundry. Our engineered chemistry together with our proprietary heat treatment allows us to soften this alloy to the point where we can then drill and tap holes, as well as broach keyways. After machining, we can heat treat the casting to harden this alloy to a minimum of .
