What are SS 446 Coils / AISI 446 Coils?

SS 446 Coils / AISI 446 Coils are high-chromium ferritic stainless steel coils containing approximately 23–27% chromium. This high chromium content provides exceptional resistance to oxidation, scaling, and corrosion at elevated temperatures. AISI 446 is specifically designed for service in aggressive environments where conventional stainless steels fail.

  • Exceptional resistance to oxidation and scaling
  • Ferritic structure ensures superior thermal stability
  • High chromium improves corrosion resistance
  • Low nickel content reduces thermal expansion
  • Maintains structural integrity at 1000°C+
  • Better resistance to sulfur-bearing environments

Frequently Asked Questions

Quick answers to common queries about Stainless Steel 446 Coils.

SS 446 / AISI 446 coils are high-chromium ferritic stainless steel coils known for excellent oxidation resistance at elevated temperatures.
Thicker SS 446 coils cost more because they require more raw material and higher processing energy per unit.
Larger or custom-sized coils typically increase the price due to higher material usage and specialized mill setup requirements.
Longer coils may reduce per-unit handling costs but increase total purchase cost due to greater material volume.
Premium finishes like BA or polished surfaces increase cost because they involve additional processing and quality control.
Since chromium and other alloying elements make up a major portion of production cost, market price changes directly affect final coil pricing.
Yes, additional treatments such as annealing, pickling, or precision rolling raise production expenses and therefore the final price.
SS 446 coils are uniquely suited for high-temperature furnace liners and heat-treatment equipment due to their superior scaling and oxidation resistance.
