When it comes to choosing an outdoor furnace, there are a few key factors to consider. One critical factor is the type of steel used in construction because it will directly impact the longevity of your furnace. Titanium Enhanced 409 Stainless Steel is a great choice compared to mild steel for several reasons. In this blog post, we will discuss five of the reasons we at HeatMasterSS use Titanium Enhanced 409 Stainless Steel to build the most rugged and long-lasting outdoor furnaces available.
Alloy 409 is a general-purpose Titanium stabilized, ferritic stainless steel. It’s commonly used in automotive exhaust systems where the environment can be especially taxing on the steel. Titanium Enhanced 409 Stainless Steel is also ideal when corrosive elements are present, and for harsh outdoor environments.
Because Titanium Enhanced 409 Stainless Steel is a high-quality alloy it offers many benefits compared to other types of steel. Some of the main advantages include:
The biggest difference between Titanium Enhanced 409 Stainless Steel and mild steel is in the numbers.
Mild steel is a light and affordable low-carbon steel that doesn’t contain many other elements beyond iron. Because it doesn’t have a large amount of carbon, mild steel generally has less tensile strength than high carbon steel. It also means that it is more susceptible to rust if not properly coated.
Titanium Enhanced 409 Stainless Steel has higher strength and heat tolerance compared to mild steel which is mainly due to the amount of chromium content. Titanium Enhanced 409 Stainless Steel contains a minimum of 11 percent chromium, which gives it better corrosion resistance capabilities.
Stress corrosion cracking can lead to sudden failure at elevated temperatures, especially in certain chemical environments. Titanium Enhanced 409 Stainless Steel resists corrosion in the harshest environments, making it perfect for outdoor use and wood-burning outdoor furnaces that produce wet ashes, water jacket sweating, and other corrosive chemical elements.
Thermal expansion is how much a type of steel expands and contracts with heating and cooling. To prevent damage to the firebox and water jacket thermal expansion needs to be kept to a minimum. Titanium Enhanced 409 Stainless Steel has a low thermal expansion coefficient.
As you can imagine, heat transfer performance is crucial to an outdoor furnace design. Titanium Enhanced 409 Stainless Steel has the best heat transfer performance of any stainless steel including 304 stainless steel. The high heat transferability of Titanium Enhanced 409 Stainless Steel keeps your water at a higher temperature which ultimately saves you money on fuel.
Because it is made to transfer heat, Titanium Enhanced 409 Stainless Steel can do the same job at lower thicknesses, which saves costs on thicker materials. Titanium Enhanced 409 Stainless Steel is also typically more cost-effective than 304 stainless and other titanium alloys making it an economical choice for an outdoor furnace.
Outdoor furnaces convert wood through a three-stage gasification process. The synthetic gas that is produced can be used to heat your home, barn, and outbuildings all at the same time. By optimizing the burning of biomass, gasification converts up to 95% of the fuel you use into heat keeping you comfortable and saving money. We at HeatMasterss have put our G-Series through years of rigorous testing and earned the highest efficiency ratings in the industry.
Time is a gift that you can’t get back, which is why HeatMasterSS outdoor furnaces are designed to make your life easier. Our furnaces are made to last, with Titanium Enhanced 409 Stainless Steel steel that resists corrosion, can withstand higher continuous temperature, and transfers more heat to save you fuel.
When you are looking to heat your home, barn, pool, or outbuildings it’s good to know that you can choose an outdoor furnace that is backed by an extensive network of local, professional dealers.
