Heat processing relies on stainless steel's thermal stability:
Elevated Temperature Strength:
310S stainless channels (ASTM A276) maintain 205MPa yield strength at 1000°C, supporting 50kg loads in ceramic firing ovens. Italy's Biesse uses these.
Oxidation Resistance:
Channels with 25% chromium and 20% nickel content resist scale formation, lasting 5 years in continuous 900°C service-10x longer than carbon steel. Germany's Bosch employs these.
Dimensional Stability:
Channels with 50×25×3mm dimensions maintain ±0.5mm tolerance after thermal cycling, critical for uniform baking. US's General Mills uses these in cereal production.
Regional Standards:
Chinese industrial ovens use GB/T 4237 06Cr25Ni20 channels, while US facilities prefer ASTM A269 310S channels for better weldability.
