Jun 22,  · High-chromium (25 – 35% Cr) cast irons are recommended during operation in oxidizing acids, especially in nitric acid. They exhibit good corrosion resistance in sulfuric acid of any concentration at temperatures up to 80°C, and in phosphoric acid at a concentration ≤ 60% up to the boiling temperature and with a concentration of ≤ 85% up to 80°C.

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

Conclusions · 1. Austenite in high-chromium cast irons is stable up to 500°. · 2. The resistance of high-chromium cast iron to hydroabrasive wear is minimal in 

1. Introduction High chromium cast irons (HCCIs) are primarily used in mining machinery, wear resistant lining board, crusher jawplate, etc. because of their excellent wear resistance and high hardness [1], [2], [3]. But the poor toughness restricts their further development [4], [5].

The objective of this study is to clad low-carbon steel (LCS) to high-chromium cast iron (HCCI) by using hot rolling process. The results show that the brittle HCCI can achieve plastic deformation when being cladded with LCS. The carbides of HCCI layer were broken, fractured, and refined. However, some carbide pits could be observed between the fractured carbides. The deformation mechanism of

OSTI.GOV Journal Article: High-chromium and high-silicon cast irons

High chromium cast iron (HCCI) is the third generation of white cast iron, which has better wear resistance and higher toughness than common white cast iron. They are considered to be excellent wear-resistant materials, and are widely used in many fields [ [15], [16], [17], [18] ].

Description Wear-resistant high chromium cast iron pipes are composed of 2 layers of metal, the outer layer is generally Q235 ordinary steel pipe, and the innerHigh chromium alloy,Optional welding and cutting, high wear resistance and heat resistance.

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 carbides.

High chromium cast irons (HCCI's) exhibit very good mechanical properties and offer benefits for a range of manufacturing applications.

General properties of cast iron. A popular grade of white iron is high chrome white irons, ASTM A532. This contains nickel and chromium for good low-impact abrasion applications [4]. Malleable cast iron. Malleable cast irons are formed via a slow annealing heat treatment of white cast iron. This results in the conversion of carbon, in the

In the present work, high chromium cast irons (HCCIs) with different high carbon ferro-chrome (HCFC) content were cladded on a low carbon steel (LCS). The microstructure and mechanical properties

With respect to mechanical properties (σ r = 480 MPa; hardness 290 -340 HB) high-chromium cast iron surpasses high-silicon cast irons . In as number of cases chromium cast irons are additionally alloyed with molybdenum. Molybdenum in white cast iron is within eutectic carbide and matrix phase.
