The alloy decides how hot a belt can run and how it resists oxidation and corrosion. The table below gives typical compositions and maximum operating temperatures for standard belt materials.

Guide values. Practical limits depend on load, atmosphere and contaminants.
Maximum temperature is a guide: load, atmosphere and contaminants all reduce the practical limit. Ask us to confirm the right alloy for your process.
