A powder coat finish is highly recommended for color customization, durability, and to minimize maintenance. In order to truly fight corrosion, Brown Jordan Outdoor Kitchens recommends powder coating your outdoor kitchen cabinets regardless of the grade of stainless you decide. Why Add Powder Coating to Stainless Steel? The addition of molybdenum (in marine grade stainless steel) only retards corrosion – it does not stop it. Consequently, regardless of whether you use 304 or 316, exposed stainless steel (no powder coating) requires maintenance. It is also important to note that stainless steel is not stain proof it is stain less. 304 tends to be less expensive than 316 as well, and it is more than adequate in most outdoor kitchen applications. Truthfully, the majority of appliance and grill manufacturers use 304 grade stainless steel – even in coastal areas – provided the steel is regularly cleaned, maintained, or kept covered. In other environments – the desert, the mountains, in the city, or in a suburban backyard – 304 is the way to go. If you live in a coastal area, 316 is recommended for your outdoor kitchen cabinetry due to its corrosion resistance in salty areas. Should I Use 304 or 316 for My Outdoor Kitchen Cabinetry? For this reason, 316 is invaluable for industries and appliances that regularly engage in salt or saltwater, and it is typically marketed as a marine metal for its use in wet weather and seawater conditions. Molybdenum provides a high resistance to heat, salt, and other chemicals in environments that are rich in salt air, giving 316 stainless the distinction of being “marine grade”. While the main alloys in 300 grade stainless steel are chromium and nickel, other additional alloys can include manganese, titanium, aluminum, copper, nitrogen, phosphorus, selenium, and molybdenum. The key alloy that distinguishes 304 from 316 is the addition of 2% molybdenum in the 316. As a result, 316L resists even higher temperatures and higher levels of corrosion than 316, but it is more susceptible to damage from acid. 316 contains several variations, such as 316L, which contains less carbon than 316.
It is highly durable, easy to clean and weld, and it is corrosion-resistant and heat-resistant. 316 Stainless Steelģ16 stainless steel is typically found in marine vessels and chemical storage units. It is commonly used in kitchen equipment, cutlery, pipes and tubing, and military vehicles. While it is oxidation resistant, it can be corroded by chloride and salt substances. 304 Stainless Steelģ04 is the most common grade of stainless steel and is found in most appliances. Most steels have a body-centered cubic grain structure, while austenitic steels have a face-centered cubic structure, meaning their atomic makeup allows them to be even more ductile and heat resistant than conventional types of stainless steel s. While visibly indistinguishable, the chemical composition differs, making each grade more useful in certain applications.Īll 300-grade stainless steels are austenitic (non-magnetic), rather than ferritic (magnetic). The grades are determined by their alloy composition, although both are high-quality and durable options for your outdoor kitchen appliances. The two most common grades of stainless steel for outdoor kitchens are 304 and 316 (marine grade) due to their strength. For a material to be considered stainless steel, at least 10.5% of the molecular make-up must be chromium.
Stainless steels are iron alloys mixed with chromium, rendering them an incredibly durable and heavy-duty material.
