How to ensure all your grate bars with high and stable quality? Here, Yongxing produces them with established procedures and rules. We will make your grate bar as the following process:
- Open mold/ or use existing mold
- Chemical composition analysis
- Make it clean
- Dimension inspect
- Tensile strength test
- Hardness test
In these chemical compositions, our most commonly used materials are cast iron fire bars, like HT150, HT200, HT250, RTSi5, QTSi5, etc. Take our RTSi5 material, for example. Once you need a fire grate bar that can bear high temperatures up to 1200℃, this kind of material is the best option.
Some customers may need a temperature higher than 1200℃ or need them to work more long lifetime. They are welcome to choose our alloy steel grate bar, with materials of ZG35Cr24Ni4SiN. The side plate also uses ZG35Cr24Ni4SiN. Endplate use QTRSi5.
