Overview of chrome and carbide wear resistant high chromium steel plate
Chromium Carbide (Cr3C2) is a hard, wear-resistant ceramic compound consisting of chromium and carbon atoms. It is a metallic carbide known for its exceptional hardness, high melting point, and excellent corrosion resistance. Chromium carbide is widely utilized in applications where resistance to wear, corrosion, and high temperatures is crucial, making it a vital component in various industrial sectors.
Features of chrome and carbide wear resistant high chromium steel plate
-
High Hardness and Wear Resistance: Chromium carbide has a Vickers hardness of around 1300 Hv, which is significantly higher than most steel alloys, providing excellent resistance to abrasion and wear.
-
High Melting Point: With a melting point exceeding 1890°C, it can maintain its structural integrity and properties in extremely high-temperature environments.
-
Corrosion Resistance: Forms a passive chromium oxide layer when exposed to oxygen, providing inherent corrosion resistance, particularly against oxidation and acidic environments.
-
Thermal Stability: Exhibits good stability at high temperatures, making it suitable for use in high-temperature applications such as heat exchangers and furnace components.
-
Chemical Resistance: Resistant to many chemicals, including acids, except for strong oxidizers like nitric acid.
-
Bonding Enhancer: When added to metal matrix composites or as a coating, it can enhance bonding between the substrate and other materials.

Parameters of chrome and carbide wear resistant high chromium steel plate
Chrome and carbide wear-resistant high Chromium steel plate is an alloy that combines high chromium content with high wear resistance properties. The composition of the plate may vary depending on the specific grade or manufacturer, but generally it contains a higher percentage of high Chromium content compared to standard grades of mild steel or stainless steel.
The wear resistance of chrome and carbide steel plates is due to the presence of theCr compounds in the material. These compounds can form wear deposits on the surface of the plate, reducing its surface area and thus increasing its wear resistance. Additionally, some versions of the plate may contain other wear-resistant additives such as boron, titanium, or molybdenum, which further enhance its wear resistance capabilities.
In terms of parameter, some common parameters used for Chrome and Carbide Wear-resistant High Chromium Steel Plate include:
* Hardness: This is a measure of how hard the material is to cut, grind, and polish. A higher hardness indicates better wear resistance.
* Wear-resistance factor: This is a ratio of the maximum number of cycles before the material reaches failure under normal operating conditions to the minimum number of cycles required to achieve a given load load factor. A higher wear-resistance factor indicates greater wear resistance.
* Temperature coefficient of thermal expansion (TDE): This is the rate at which the temperature of the material changes in response to changes in temperature. A lower TDE indicates greater stability and reduced wear.
* Chemical corrosion resistance: This is the ability of the material to resist chemical attack from acids, solvents, or other substances that may cause damage to the surface.
It’s important to note that these parameters may change over time due to changes in temperature, humidity, and other environmental factors, so it’s important to regularly monitor and maintain the material to ensure optimal performance.
