The Five Families of Stainless Steel

June 28th, 2018 by Natalie Mueller

Filed under: Stainless Steel

At Skolnik we offer a host of steel containers — our stainless steel drums offer an ideal solution for products requiring the purity, compatibility and strength of stainless steel. But just like Skolnik offers different families of products, there are different families of stainless steel. Five to be exact: austenitic stainless steel, ferritic stainless steel, martensitic stainless steel, duplex stainless steel and precipitation hardening stainless steel. The families are classified by their crystalline structure.

 

Austenitic stainless steel is the largest family. About two thirds of all stainless steel produced falls into this category. Their crystalline structure is achieved by alloying with sufficient nickel and/or manganese and nitrogen. These stainless steels maintain their microstructure at all temperatures so they can’t be hardenable by heat treatment, but can be strengthened by cold working to an extent.

Austenitic stainless steel is great for formability and weldability, they are also essentially non magnetic. They’re often used for tanks, containers, storage vessels, architecture and the like.

 

Ferritic stainless steel has a structure more similar to carbon steel, contains between 10.5% and 27% chromium with very little or no nickel. Due to the chromium structure, ferritic stainless steel also holds its structure at all temperatures and is not hardenable by heat treatment. However, they are magnetic and are problematic to weld.

Welding creates microstructural problems so ferritic stainless steel is not used in the construction of large, heavy walled vessels and tanks and structures.

 

Martensitic stainless steels form a family that can be heat treated to provide the adequate level of mechanical properties. Martensitic stainless steels are magnetic and are less corrosion resistant than ferritic and austenitic due to a lower chromium content.

However, their high carbon content enables them to be significantly hardened so they are commonly used for knives, razor blades, cutlery and tools.

Duplex stainless steel’s structure is a combination of that of austenite and ferrite, usually at a 50/50 or 40/60 mix. It’s characterized by high chromium and molybdenum with lower nickel contents. The mixed microstructure results in higher resistance to chloride stress corrosion.

Duplex stainless steel can be difficult to weld properly, but can sometimes be a cost-effective solution for chemical processing, transport and storage, and marine environments.

 

Precipitation hardening stainless steel has corrosion resistance comparable to austenitic varieties but can be hardened to even higher strengths than martensitic steel. Precipitation hardening stainless steel is often used for gears, valves and other engine components, nuclear waste casks, and other pieces in aerospace and other high-tech industries.

 

Beyond that, there are over 150 grades of stainless steel.

Skolnik stainless steel drums are available in a variety of gauges and sizes and are stainless types 304 and 316, both austenitic, and 409, a ferritic stainless steel. And our products are built thicker, heavier and stronger than industry standards require.

 

The Plastic Pollution Problem and the Stainless Steel Solution

Filed under: Industry News, Stainless Steel

Why is plastic such popular headline material this year? Well, because plastic pollution has finally reached a boiling point. Even with an increased awareness and consciousness of recycling, research warns that the amount of discarded plastic in just the ocean will triple in the next decade. If this warning becomes reality, in ten years there will be more plastic in our oceans than there are fish.

Sounds bleak, right? Well, the good news is that just as we’re all responsible for this issue, we can also all chip in to help. Every small change to our plastic-using habits helps, and we’ve already taken a huge first step by being more aware of the problem.

Stainless steel is considered the most reliable and safest material for industrial grade containers. Stainless steel drums, like the ones we manufacture at Skolnik, have long been a favorite for the storage and transportation of chemicals, consumables, hazardous materials and more. In recent years, plastic drums and containers entered the scene and boasted their superior lightweight and flexibility. However, there is a reason stainless steel drums are still considered the gold standard. Not only can they promise levels of durability and sanitation that porous plastic cannot, but they are also vastly more eco-friendly.

And, with plastic pollution clogging our oceans and newsfeeds, more businesses and individuals are actively trying to cut down on their plastic waste, and they are turning to stainless steel to help. In fact, the global stainless steel market is currently being driven by an increased demand for consumer goods. Consumers are picking up reusable stainless steel straws to cut back on plastic straw use, businesses are implementing stainless steel water refill stations for their employees or patrons, and more.

We hope that stainless steel products such as our stainless steel drums continue to help people cut down on plastic waste and reverse the disastrous predictions of environmental experts.

 

Keg Theft Concerns Highlight the Value of Stainless Steel Barrels

We here at Skolnik proudly serve a wide variety of industries with a full range of products, including the ever-popular 55-gallon stainless steel barrel. Our 55-gallon stainless steel wine barrel has deepened our ties with the beverage industry, where we’ve noticed a unique container challenge recently: keg theft.

Keg theft has plagued the beer industry for years. With the rise of DIY art and furniture, more and more craft beer enthusiasts are pilfering kegs from their local bars in hopes of making a fun conversation piece for their living rooms. Of course, this is illegal and hurts everyone from the bars — who are merely renting the kegs from their distributors — to the brewers — who now need to replace the container. With a sticker price on average of $130+ per beer keg, it’s not a cheap replacement.

Now, the distribution models of wine and beer are certainly different, and kegs are more vulnerable than a 55-gallon steel barrel, but it is certainly as much of a problem if inventory goes missing.

The beer industry has deterrents in place — hefty deposits motivate renters to return them safely– it is yet to be seen if such security standards are required for wine barrels. Luckily, if were to come to it, there are plenty of notes for our wine partners to take from the beer industry as they navigate the problem.

At Skolnik, we regularly receive requests for barrels to use in similar DIY projects. Luckily, as a wholesale supplier, we are at a lower risk for the kind of theft plaguing the beer industry. Our customers come to us for bulk purchases of containers, not individual rentals. Even so, by keeping a keen eye on the troubles faced by our partners in other parts of the beverage community can help protect us from future harm to our own businesses.

Some very impressive work has come out of peoples’ interest in these industrial containers, but the beauty of the piece is only tarnished by ill-gotten materials. We agree that the Skolink brand 55-gallon stainless steel barrel is a piece of art, just make sure you’re not committing a crime to get your hands on them.

Linings and Seamless Solutions for Process Drums

Steel drums are the long-time favorite container for a multitude of different industries and uses. They are strong, heavy, and, in many cases, reusable because steel is stronger, heavier and more easily reconditioned than many other materials. But what about materials that react negatively with steel? What about industries that are held to incredibly stringent contamination standards? Steel drums can work for them too. Skolnik manufactures a selection of steel process drums and steel drum linings to ensure chemicals and consumables remain safely contained.

Drum Linings

Any materials that could react with bare steel must be put in a lined drum or another compatible package. Drum linings are specifically designed to safely interact with the contents and help protect both the product being contained and the steel drum itself from being compromised. They undergo their own testing before they are added to the drum to guarantee their strength and safety.

The lining most commonly used at Skolnik Industries is an epoxy/phenolic lining which is created by combining heat-cured epoxy resin with thermosetting phenolic resin. The chemical resistance these two resins create make a lining that is ideal for drums containing liquids such as food products, detergents, latex paints and/or materials with a pH range above 7.

Seamless and Crevice-Free Drums

Skolnik developed their Stainless Seamless Crevice Free Drum to provide an effective container for contents that may encourage and/or be contaminated by the growth of bacteria in the crevice of a standard steel drum. The seamless drum has no crevice — it is smooth where the body and head meet.

Skolnik’s welding engineer, quality department, and maintenance team spent nearly a whole year designing and then fine-tuning the best, most effective process for machining a truly seamless drum that met Skolnik’s high standards of quality control. We are proud to say that since 2009, Skolnik Industries’ seamless drums have supported the pharmaceutical industry, chemical industry and food-processing industry as a safe, strong and sterile process drum option.

 

As always, the Skolnik team is standing by, ready to help guide you toward the right steel process drum or container for your business, facility and/or contents.
