chromium in cast iron

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

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.

The determination of chromium in cast iron and steel. T. S. Harrison and H. Storr, Analyst, 1949, 74, 502 DOI: 10.1039/AN9497400502.

for cast iron with 27% chromium, there is no difference between 20°C and 80°C. A least noticeable increase in the thickness of the oxide film (Cr 2 O 3 passivation coating) on this alloy starts

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] 

high chromium white cast iron alloys, including their classifications, their standard specifications in USA, China and Australia, their main usages and the 

In the present work, the microstructure and crystallography of M 7 C 3 carbide in chromium cast iron are studied by examining the tip structures of growing M 7 C 3 carbide in details. Thus, the M 7 C 3 carbide growth as well as its intrinsic defects is discussed evidentially. As a result, a growth mechanism of M 7 C 3 carbide is put forwards

WSF can produce for you a 15% and 25% Hi-Chrome alloy iron. Typically used in applications of wear resistance and long term heat resistance are required, such as impellers, turbines, and grinding applications. The iron expresses a very hard surface. These high-chromium alloys attribute their superior hardness to the presence of chromium

High-chromium white iron alloys allow massive castings (for example, a 10-tonne impeller) to be sand cast, as the chromium reduces cooling rate required to produce carbides through the greater thicknesses of material. Chromium also produces carbides with impressive abrasion resistance. [citation needed]

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

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

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

The initial as-cast microstructure of high-chromium white cast iron (2.08% C, 12.1% Cr), including austenitic dendrites in a matrix of a eutectic mixture of austenite and M7C3 carbides.

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, 

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.

Experimental results indicate that a linear relationship between the wear lose and the testing time exists for high chromium white cast irons. Apparent scratch
