In summary, the conversation discusses the search for a raw material with properties similar to steel, but with less noise when meshing with other parts. Suggestions such as polymers like Cast nylon and HDPE are mentioned, but the challenge is finding one that can withstand a temperature of 200°C. The conversation also touches on the application and the cause of the noise, with the suggestion that a redesign of the teeth engagement may be a more effective solution.

Hi everyone,

Can anyone suggest a raw material that has the properties similar to steel and produce less noise when meshing with other part. I thought of polymers like Cast nylon, HDPE etc, but the issue is, it has to withstand a temp of around 200°C, during working condition.

Thanks,
r.murali

Depends what you mean by properties similar to steel, as polymers are in no way similar to steel. Especially Nylon, the very best Nylon I've seen has a Moly filled that has about 0.25- 0.3 the tensile strength of mild steel.

What application is this for? Why do yo want 'less noise'? What is causing the noise?

I assume this is a gear as you use the word mesh. If it's gears a redesgin of how the teeth engage is more likely to solve noise problems.
 

FAQ: Find Suitable Material to Withstand 200°C & Produce Low Noise

1. What materials are suitable for withstanding 200°C?

Materials that are suitable for withstanding 200°C include metals such as stainless steel, aluminum, and titanium, as well as ceramics and some polymers. These materials have high melting points and can withstand high temperatures without degrading or losing their structural integrity.

2. How do materials produce low noise?

Materials can produce low noise through various mechanisms, such as sound absorption, sound insulation, or vibration damping. For example, materials with porous structures can absorb sound waves, while materials with high density and stiffness can block sound waves from passing through. Additionally, materials with viscoelastic properties can dampen vibrations and reduce noise levels.

3. Can any material withstand 200°C and produce low noise?

No, not all materials can withstand 200°C and produce low noise. Some materials, such as plastics and rubber, may have good sound absorption properties but cannot withstand high temperatures. It is important to select materials that have both the desired temperature resistance and noise-reducing capabilities for the specific application.

4. Are there any trade-offs between temperature resistance and noise reduction in materials?

Yes, there can be trade-offs between temperature resistance and noise reduction in materials. For example, materials with excellent temperature resistance may not have the best sound-absorbing properties, and vice versa. It is essential to carefully consider the specific requirements and priorities of the application when selecting a material.

5. Are there any tests to determine a material's ability to withstand 200°C and produce low noise?

Yes, there are various tests that can determine a material's ability to withstand high temperatures and reduce noise levels. These include thermal conductivity tests, heat resistance tests, and sound absorption tests. It is important to conduct these tests under relevant conditions to accurately assess the material's performance in the intended application.
