Heat Treatment Technology of High Chromium Iron
2020-10-2 Some high chromium iron castings can obtain the required hardness in the as-cast state, but most of them need heat treatment to meet the hardness requirements. Heat treatment is almost a necessary process for every high chromium iron casting. Reasonable quenching can make the casting obtain the best ability to resist abrasive wear.

2014-1-30 thermal treatment was carried out which consisted of the austenisation at 975°C for 1 h, cooling by moving air down to 300 °C, and keeping alloy samples for 8 h. The results of cast alloys were compared with those of thermal treatments to determine the existence of a decrease in the wear-out properties of high chrome alloys.

Some of the curves in the "Abrasion Resistant Cast Iron Handbook" suggest some high chrome irons can end up with vastly different hardnesses even after tempering to the same temperature, depending on retained austenite.
