Figure 2 shows the changes in the hardness when increasing the temperature and the effect of treatment time for the highchromium white cast iron alloy in the initial ascast state. Figure 2 (a) shows that the increase of temperature also increases the hardness.

Research Article Heat Treatment in High Chromium White Cast Iron Ti Alloy Central Metallurgical RD Institute (CMRDI), .

highchromium iron was studied using Metallurgical optical microscopy (OM) and compared to the Hadfield steel. The hardness and unnotched charpy impact strength of the HCWi alloy and Hadfield steel were examined at ambient tem perature in the ascast and heattreated conditions. A pinondisc test at linear speed of m/s and a 10 N normal load was employed to evaluate the wear behavior ...

Chrome could improve the hardening capacity of heat treatment, and especially improve the abrasive resistance. b. In addition, high content of Cr could improve the corrosion resistance, so it is an important alloy for stainless steel.

Highly wearresistant chrome cast iron. Martensitic matrix with high carbide fraction results in hardness values of 6166HRC with simultaneous supporting effect of the matrix. High heat hardening and good scaling resistance due to alloy elements Cr, Mo and V. Components subject to high wear stress with working temperatures up to approx. 400°C and moderate impact stress: Protective segments ...

Like wrought steels, carbon cast steels can be classified according to their carbon content: Low carbon cast steel (C percent) is relatively soft and not readily heattreatable; medium carbon cast steel ( percent C percent) is somewhat harder and amenable to strengthening by heat treatment; high carbon cast steel (C percent) is used when maximum hardness and wear ...

The article presents results of heat treatment on the high chromium cast iron. The study was carrying out on samples cut from the casting made from chromium cast iron. Those were hardened at different temperatures, then tempered and soft annealed. The heat treatment was performed in a laboratory chamber furnace in the Department of Engineering Alloys and Composites at Faculty of Foundry ...

We make high chrome cast iron, ductile iron casting and lost casting in Ningbo, China 11. We can do different kinds of surface treatment after casting, such as machining, polishing, and plating.

The invention discloses a heat treatment method of nickel hard cast iron. The nickel hard cast iron comprises the following chemical components in percentage by weight: % of carbon, % of silicon, % of manganese, % of sulfur, % of phosphorus, % of chrome, % of molybdenum, % of nickel, and the balance of Fe; the heat ...

High Chrome Cast Iron Heat Treatment. high chrome cast iron heat treatment – Grinding Mill . The Influence of Heat Treatment on Wear Resistance of High Cr.

My question is, can high chrome cast iron be "heat treated" to reharden to 500 HB after annealing or even tempering to 400? 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.
