Different combinations of critical and subcritical heat treatments variously modify the initial as cast microstructure of high chromium white cast irons leading to secondary carbide precipitation

3/19 · In cast irons for high temperature or chemical service, it is normal to keep the P content below 0.15 %. Effects of chromium Chromium has three major uses in cast irons namely (i) to form carbides, (ii) to impact corrosion resistance, and (iii) to stabilize the

High chromium cast iron pipe is an alloy steel intended for high temperature and high pressure services.

It was found that the primary carbides in the hypereutectic high chromium cast iron were all refined to different levels after different 

Prevent graphitization. Chromium is added to gray iron, Can refine graphite, Increase pearlite, Improve strength, hardness and white mouth width. But when the addition amount exceeds

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 research reported in the paper concerned the conditions of cooling high-chromium cast iron with about 15% Cr content capable to ensure 

2/3 · High chromium cast iron is one of the wear resistant materials used in a variety of applications where stability in an aggressive environmental is a principal requirement. These applications include slurry pumps, brick dies, several pieces of mine drilling equipment, rock machining equipment, and similar areas [ 1 , 2 ].

chromium cast iron after Fe–Ti inoculation treatment. The article proves that the use of the inoculant can change the primary structure of chromium cast iron, increasing its impact strength by

High chromium white cast irons (HCWCI) are known as abrasion-resistant cast irons and represent one of the most complex microcomposite 

The high chromium cast iron has good wear resistance and is widely used in slurry pumps and hot strip rolls due to its good wear resistance.

1/23 · Conclusions. 1. For high boron white cast iron, with the increase of chromium, the microhardness of boride increases, and the morphology of boride changes from continuous network to less continuous distribution. 2. With the chromium increase, martensite appears in the matrix, and its volume percentage increases.

The variations of microstructure and mechanical properties of a high-chromium cast iron for rolls were studied from as-cast to the final heat treatments.

It has been proved that an addition of boron carbide and shredded steel scrap introduced as an inoculants to the chromium white cast iron changes the 

Medium chromium white cast iron and medium chromium-silicon white cast iron (both belong to KmTBCr8) have been widely used in China. The main features of these irons are the alloying of carbon and chromium to give a ratio of Cr/C ≈ 3, and the formed eutectic carbide is of the type M7C3, thus giving the irons an excellent combination of properties and higher

Studies covered the cast iron containing chromium in a concentration at which graphite is still able to preserve its vermicular form. The effect 

Halnn Solid CBN Inserts process high chromium cast iron cast iron itself hardness is not high , we commonly choose Brinell hardness (between HB170~210). For the factory of processing gray cast iron parts with small batch production, people will choose carbide insert which will be more economic, such as YG series.

The cast iron is suitable for use in vane wheel, protecting sleeve and protecting board of slag gout pump, lining board and hammer of crusher, 

11/15 · Based on the mechanical properties and the wear test, this cast iron is expected to demonstrate a six-time longer life in service, compared to the currently used cast iron. The

The term “Nihard” is under- stood as white cast irons on the chromium-nickel base, which have high hardness and wear resistance. The chromium
