HRC56-64 Hardness Nickel-Chrome-Tungsten Composite Liner for Twin Screw Extruder

We are a professional manufacturer of nickel base alloy, Hastelloy alloy, tungsten carbide alloy, cobalt base alloy and H.I.P liner sleeve.

We have provided super wear-resistant high corrosion resistance bushing for many domestic and foreign parallel twin-screw extruder customers and modification enterprises, and can be developed according to customer needs, combined with the actual conditions of high quality non-standard products, Oze product performance is excellent, stable quality, reasonable price, timely delivery, perfect after-sales.

Nickel-Chromium- Tungsten alloy has excellent abrasion resistance and corrosion resistance. The increase of Cr content in the nickel-chromium alloy matrix contributes to the oxidation resistance, high temperature resistance and corrosion resistance of the alloy. At the same time, the addition of CrB is better than WC. The microhardness of CrB is as high as 4000-4200DPH, which is close to diamond. It is more conducive to improving the overall strength of the alloy. Due to the high density of WC, it is about 15.7g/cm3, while the matrix of nickel-chromium alloy is only about 8g/cm3. The melting is caused by the uneven surface and depth of the alloy due to the easy segregation of WC, so the content and particle size of WC must be controlled.

Nickel-Chromium-Tungsten alloy( we call OS 02H) hard phase increased to about 50%, OS02 is only ten to thirty,Moreover, the fusion is not sufficient, and the microscopic pores are relatively obvious, which is reflected by the Rockwell hardness HRC of only 52-55.While the Rockwell hardness of nickel chromium tungsten alloy (OS02H) is HRC56-64, the conventional control is HRC58-60. The service life is 3-5 times longer then WR5 or CPM10V.

Nickel-Chromium-Tungsten alloy( OS02H )on the basis of Ni60 in accordance with foreign twin screw working conditions of the formula, greatly improved Hard phase carbides (containing tungsten carbide chromium carbide and other carbides), and the nickel pool fullDissolve. Our Ni-Cr -W alloy layer can reach HRC64 is the best proof.

1. Improved Wear Resistance: The bimetallic design provides superior wear resistance compared to traditional liners, resulting in longer service life and reduced downtime.
2. Corrosion Resistance: The inner layer of the liner is made of a highly corrosion-resistant material, which protects the extruder barrel from damage caused by corrosive materials or processing conditions.
3. Enhanced Performance: The liner's unique design helps to improve process efficiency, reduce energy consumption, and increase throughput.
4. Cost-effective: The use of bimetallic sleeves can be a cost-effective alternative to replacing the entire extruder barrel, especially when dealing with high-wear applications.
5. Easy Installation: The sleeve can be easily installed and removed, allowing for quick maintenance and replacement.

Overall, the Twin Screw Extruder Bimetallic Sleeve Liner offers a durable, efficient, and cost-effective solution for extrusion processing.

Bimetallic screw and barrel for extruder machine spare parts are used in the plastics industry for the processing of plastic materials, such as polyethylene, polypropylene, PVC, PET, and more. These spare parts are made from two different materials, with a wear-resistant alloy being used for the outer layer and a more heat-resistant alloy used for the inner layer. The wear-resistant layer is typically made of a material such as tungsten carbide, while the inner layer is made of a material such as nitride steel.

The use of bimetallic screw and barrel spare parts in an extruder machine offers several benefits, including:

1. Increased durability and lifespan: The wear-resistant outer layer provides increased resistance to wear and corrosion, which can extend the lifespan of the screw and barrel.
2. Improved performance: The use of two different materials in the construction of the screw and barrel can improve the performance of the extruder machine, as the heat-resistant inner layer can withstand higher temperatures and the wear-resistant outer layer can provide better mixing and conveying of the plastic material.
3. Reduced maintenance costs: Bimetallic screw and barrel spare parts can reduce maintenance costs over time, as they are more durable and require less frequent replacement than standard screw and barrel components.

Overall, the use of bimetallic screw and barrel spare parts in an extruder machine can improve the efficiency and productivity of the plastic processing operation, while reducing maintenance and replacement costs.
