310S (1.4845) vs. 316 (1.4401): High-Temperature Resistant vs. Marine-Grade Stainless Steel

310S (1.4845): The Heat Master

Composition: High Chromium (24-26%) & Nickel (19-22%).

Key Strength: Outstanding resistance to oxidation and scaling at very high temperatures.

Best For: Furnace parts, kilns, burners, catalytic converters, heat exchangers.

Temperature Limit: Up to 1150°C (2100°F).

316 (1.4401): The Corrosion Fighter

Composition: Contains Molybdenum, boosting corrosion resistance.

Key Strength: Superior resistance to chlorides (saltwater) and general corrosion.

Best For: Marine environments, chemical processing, food equipment, medical devices.

Temperature Limit: Good for moderate temps, but less for extreme heat than 310S (around 870°C max).

Key Takeaway

Choose 310S for: High heat applications where rust from chlorides isn't the main issue.

Choose 316 for: Marine, chemical, or saltwater exposure where corrosion is key, but avoid extreme heat.
