Advantages of chromium carbide composites

wallpapers Industry 2020-04-03
Chromium carbide, containing 13.34% carbon, is a gray powder, orthorhombic crystal structure, insoluble in water, resistant to acid and alkali. Density is 6.65-6.68 g/cm3, melting point: 1890 degrees, boiling point: 3800 degrees. It is a high melting point inorganic material with good wear resistance, corrosion resistance and oxidation resistance in high temperature environment (1000-1100 degrees). It is used as a thermal spray material for metal surface protection and is also often used as hard alloy. Grain refiners and other wear and corrosion resistant components. The Chromium carbide based cermet has excellent oxidation resistance at high temperatures, and the surface is only slightly darkened after 5 hours of heat exposure at 982 °C. Under the same conditions, 18-8 stainless steel has been significantly damaged, and WC-6Co alloy is completely oxidized.
Chromium carbide can be used as a composite material, such as chromium carbide composite steel plate. Chromium carbide composite steel plate is composed of two parts: low carbon steel plate and the alloy wear layer. The alloy wear layer generally accounts for 1 / 3-1 / 2 of the total thickness.
The performance characteristics of the chromium carbide composite steel plate have the following aspects:
1.Impact performance
    The wear resistance is more than 15-20 times that of ordinary steel plates, 5-10 times that of low alloy steel plates, and 2-5 times that of high chromium cast iron. The wear resistance of chromium carbide composite steel plate is much higher than the methods such as spray welding.
2. Temperature resistance
   It has strong stability at high temperatures. Chromium carbide steel plates can be used at 500 ° C. Custom produced can meet the conditions of use within 1200 ° C. Other wear-resistant materials generally cannot meet such high-temperature requirements.
3.Processability
   It can be processed into different specifications and sizes according to requirements and can be tailor-welded on-site, making work convenient, and reducing work intensity.
4. Cost-effective
  Although the chromium carbide composite steel plate is more expensive than ordinary steel plates, its service life and maintenance costs are lower than everyday materials.
Trunnano is one of the world's best chromium carbide manufacturers. "We have been supplying  chromium carbide steadily, ensuring product quality, and guaranteeing stable supply prices," said Rachel, sales manager at Luoyang Trunnano.
