If your application isn’t exposed to aggressive chemicals and is instead only exposed to milder acids, then 304 stainless steel is likely the perfect fit. It’s the most readily available grade of stainless steel and typically less expensive than its common counterpart, 316 stainless steel, which offers super corrosion resistance but is very similar overall. Stainless steel is a multifunctional metal that can be used successfully for a huge range of applications, from automotive to medical devices. Pitting Corrosion – When stainless steel is exposed to environments that contain chlorides (such as seawater) Intergranular Corrosion – When you heat stainless steel in the range of 450 to 850 degrees Celsius, carbon in the steel will convert to grain boundaries which lead to corrosion General Corrosion – Triggered when stainless steel has a pH value of >1

Some common causes of stainless steel corrosion include:īimetallic Corrosion – Dissimilar metals coming with a common electrolyte coming into contact with each other (also referred to as galvanic corrosion)Ĭrevice Corrosion – Triggered when oxygen levels in a crevice are very low Though stainless steel, for the most part, is resistant in nearly every environment, the various types will react differently when put into hostile conditions that aid in corrosion. The corrosion of stainless steel only occurs under more aggressive environments or in situations where the composition of the steel contains impurities. It’s important to consider that, although 304 stainless steel can corrode, it will not rust in normal atmospheric conditions. There are more than 150 grades of stainless steel out there, and some are simply more prone to rust than others. Kitchen equipment, appliances & food processing.Though it’s used for a wide variety of applications, 304 stainless steel is most commonly used in the transportation, architectural and industrial industries. While it offers the most corrosion resistance compared with other metals and alloys, the reality is that stainless steel can rust in specific environments.īelow, we dig into the common applications of 304 stainless steel, causes of rust and how that impacts the industries that 304 stainless steel is used in.

Have you ever found yourself wondering: does 304 stainless steel rust? If so, you’re not alone – a common misunderstanding about stainless steel is that rusting is impossible.

If all the Stainless Steel screws available at your store have no ratings, insist that the store staff check the catalogues to see that what you are buying is in the 300 series or is identified as 18-8. Some manufacturers do put these identifications on the label as you can see in the photo, while many do not yet. So part of the 'bad rap' on stainless steel is that less expensive but stronger fasteners are being sold for a purpose where they are not appropriate.įor our decking and fencing, we want screws that are labelled 304 or 18-8 (the same screw, just two systems of labelling) or maybe even more corrosion resistance with a 316, but stay away from the 400 series. Others which are actually stronger, will be lest resistant to rusting. The standard screw and nail construction stainless steel are called the 300 series, or 18-8 (which means about 18% chromium and 8 % nickel). In fact there are many different formulations of 'stainless steel', each designed to work with particular problems, not just water rust. Too much chrome and it becomes brittle, too little and it can rust. Here they are putting this material mixed right into the steel. Right, Chrome, like the old bumpers that were Chrome coated.

Stainless steel is by definition a steel (actually a ferrous alloy) that has at least 12% Chromium content. All of these things are coatings put over a regular steel screw. Many new coatings exist that work even better, and are often colour matched to our wood, like green and brown screws. Just as Aluminium nails should not be used with pressure treated wood. The standard galvanised nails should not be used with Cedar because the tannic acid in cedar will react with the galvanisation. There are interesting stories about most fasteners.
