heat treatment and high chrome iron
CN102899469B Heat treatment method of high chromium wear ...
The invention discloses a heat treatment method of high chromium wear resistant white cast iron Cr28. According to the invention, high chromium wear resistant white cast iron Cr28 is heated to 1000 1050 DEG C; the white cast iron Cr28 is heated and the temperature is maintained for 1.5 3h; the white cast iron Cr28 is air cooled to room temperature; the white
Pliant25 High Chrome White Iron Penticton Foundry
26/01/2016· 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 600 BHN.

The austempering heat treatment process is helpful for the high chrome cast iron grinding balls served in the large ball mill. Key words： high chromium cast iron grinding ball; austempering; multi stage austenitizing; impact toughness; impact fatigue resistance. The grinding ball is the grinding media in the ball mill.
Heat Treatment Technology of High Chromium Iron Castings ...
02/10/2020· 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.

The invention discloses a high chrome wear resistant cast iron material and a heat treatment method. The high chrome wear resistant cast iron material is prepared from iron as a
Study on the heat treatment process of high chrome cast ...
The heat treatment and healing process of high chromium cast iron is actually a dynamic process of secondary carbide precipitation and dissolution, so the selection of quenching temperature and holding time is very important. At a certain temperature, the higher the quenching temperature is, the higher the hardenability is.
