High-chromium irons have good mechanical properties, high hardness in a cast state, low fluctuation of hardness when properties change. High-chromium 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.

Heat treatment of high chromium grinding ball is the main method to obtain good wear resistance. The research on high chromium cast iron ball mainly focuses on chemical composition selection, heat treatment process determination, modifier selection, good carbide type and wear mechanism.

2.1. High-chromium white cast iron characteristics. High-chromium white cast irons are ferrous alloys containing 11-30% Cr and 1.8-3.6% C along with variable amounts of molybdenum, manganese, copper and nickel [1]. The standard procedure most commonly used for the classification of this kind of cast iron alloy is ASTM A532-10 (2014).

of chromium cast iron microstructure and its resistance on erosion wears. Separate part of paper was devoted to discuss the bimetallic castings with chromium cast iron layer as well as typical applications of chromium cast iron castings in minig, proccesing, metallurgical and power industry.

and high abrasion, the more expensive high-Cr white cast irons can be cost effective (Farge and Barclay, 1975). Our previous research (Blickensderfer, et al., 1983) showed that the impact resistance of high-chromium white cast iron is greatly affected by heat treatment. Improvement of grinding media has been a slow process.

Part 1 High chromium cast iron machining and cutting tool selection High chromium cast iron is a kind of high hardness and high strength alloy white cast iron with high corrosion resistance wear-resistant, high chrome cast iron in the case without any heat treatment, the generally hardness of HRC45 or more, the tensile strength 650 ~ 850MPa.

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.

Machinability Investigations on High Chrome White Cast Iron Using Multi Coated Hard Carbide Tools Article (PDF Available) in Transactions of the Indian Institute of Metals 67(4) · August 2014 ...

abrasion family of alloys generally known as the high chromium irons form the basis of hard metal casting suitable for ball milling application [2]. High chromium white cast irons are multi component alloys that contain iron, carbon and chromium as major elements, and molybdemium, nickel, silicon and manganese either as

A high strength high chromium cast iron contains fine particle precipitated hard carbide. The precipitated hard carbide has an average particle size of 20 µm or less, in a martensite matrix with a hardness of Hv 500 or more, and has area ratio of from 30% to 45%. The precipitated hard carbide has a spheroidal ratio (surface area of sphere circumscribing the precipitated hard carbide versus ...

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 .

The mechanical properties of high -chromium cast irons are better than those of the high -silicon cast irons. The high-chromium cast irons respond to heat treatment when the carbon and chromium contents are appropriately adjusted. However, machining of these alloys is very difficult.

Grey cast iron is characterised by its graphitic microstructure, which causes fractures of the material to have a grey appearance. It is the most commonly used cast iron and the most widely used cast material based on weight. Most cast irons have a chemical composition of 2.5–4.0% carbon, 1–3% silicon, and the remainder iron.
