What’re the Differences between 201,304 and 316 Stainless Steel

Type 201 stainless steel is unique as it was created in response to soaring nickel prices. This means that it is cheaper, but it also has a much lower nickel content. Without as much nickel, it is not as effective at preventing corrosion.The higher levels of manganese help make type 201 one of the strongest types of stainless steel banding. Industries that prefer this type are those looking for more durability at a lower cost and are not worried about exposure to corrosive elements.Like type 304, this type is also commonly used to attach signs, and for other plumbing needs. Although it is not as resistant to corrosion, it still has good corrosion protection. Type 201 stainless steel is especially helpful in cold environments, as its toughness holds up in cold weather. To make up for its lack of nickel, you’ll find it composed of more manganese and nitrogen.As the cheapest type of stainless steel, type 201 seems the most appealing. Still, it will not hold up as long in highly corrosive environments.

Stainless steel type 304 is the more common and general-purpose type of stainless steel. In fact, this type of stainless steel is so common that it’s likely used in your household appliances and even your faucet.This type is defined by its higher nickel content than other types of stainless steel. Due to the rising cost of nickel, this makes stainless steel type 304 slightly more expensive than the other types. The nickel, however, is what makes type 304 less susceptible to corrosion. Obviously, you can see why this type appeals to the appliance and plumbing industries. It also appeals to sign and electrical industries for some of the same reasons. Fixing signs and strapping pipelines and tanks are common uses for this type of stainless steel banding. Ultimately, exposure to corrosive elements is what leads businesses to choose type 304 steel banding for their needs. It also has the same bending, shaping, and flattening abilities as type 201 stainless steel. Unfortunately, while it is more resistant to corrosion, it is less durable than other types of stainless steel. Each type of stainless steel has its unique benefits and disadvantages. Some are better suited to certain types of situations.

While type 201 has the lowest resistance to corrosion, and type 304 is more resistant, type 316 has the most. As you can probably guess, it has the highest nickel content. Obviously, this high nickel content makes type 316 the most expensive type of stainless steel banding. For some industries, however, the cost is worth it.Type 316 differs from type 304 in that it has molybdenum, an alloy that fights corrosion. Type 316 stainless steel is ideal for situations with more saline and chloride exposure.While type 304 stainless steel seems like a more economical choice, it doesn’t have the same resistance to saline and chloride. This will lead it to break down faster, costing you more in the long run when you need to replace it.Most people turn to type 316 stainless steel for outdoor and coastal applications. Of course, more severe environments will call for a higher grade of this type. Higher grades of type 316 stainless steel contain more chromium, making it more durable.In addition to molybdenum and chromium, you can find nickel, titanium, aluminum, copper, nitrogen, phosphorous, and selenium alloys. These elements help make type 316 one of the best types of stainless steel overall.The choice between types of stainless steel is entirely dependent on the application. In some cases, it is not cost-effective to splurge on type 316 stainless steel. In other cases, the higher price point works out to save you more money in the long run.

General Properties of 904L Stainless Steel

Alloy 904L was originally developed to resist environments containing dilute sulfuric acid. It also has good resistance to other inorganic acids such as hot phosphoric
