409 STAINLESS STEEL

 409 STAINLESS STEEL

409 Titanium Enhanced Stainless Steel offers many benefits when used in the application of outdoor stoves. Crown Royal Stoves are manufactured with 100% DOMESTIC 409 Stainless Steel to ensure the highest quality possible. Check out the facts below and learn why it is the superior choice.

Not All Steel Is Created Equal

Some competitors are using imported 409 stainless steel. Imported stainless steel has lower quality control standards that result in varying wall thickness, heavy inclusions from rolling, lamination and inconsistent annealing. These variables can all lead to excessive corrosion, material failures and leaks in the firebox and water jacket. Ask the competitors if they can show you mill test reports to prove they are using domestic steel.

Higher Strength and Heat Tolerance

With a maximum practical upper temperature oxidation service limit of 1450°F (789°C), 409 stainless steel possesses higher strength and heat tolerance compared to a number of steels. The 11% chromium content of 409 stainless steel accounts for these beneficial properties.

Minimal Thermal Expansion

The property of thermal expansion refers to how much a material expands with heat and contracts when cooling. Minimum thermal expansion in the steel used to construct outdoor stoves is ideal to prevent damage of the firebox and water jacket. When compared to other steel, 409 stainless steel has similar thermal expansion properties of mild steel but much better than 304 stainless steel.

Excellent Corrosion Resistance

Due to the 11% chromium content, 409 stainless steel offers excellent resistance to stress corrosion cracking (SCC) in chloride-containing environments. No 409 stainless steel failures have been reported due to chloride - SCC in wood burning furnaces. 409 stainless steel offers much better corrosion resistance than mild steel.

High Heat Transfer Capabilities

409 stainless steel is similar to mild steel heat transfer capabilities, but transfers heat much better than 304 stainless steel.
