Various applications of pipe fittings and steel fittings in various industries

Since its development over a hundred years ago, steel has become one of the most common and durable materials in the world and is now essential in a wide range of industries. This includes a number of applications exclusive to ​304 steel pipe​ fittings that take advantage of the metal's highly desirable properties.

Although steel has been around for centuries, it was vulnerable to corrosion and had other disadvantages that led scientists to find alternative alloys that would perform better in harsh conditions. Then it was found that the mixture of iron and chromium has an extraordinary resistance to rust.

What are steel alloys made of?

By definition, steel is an iron alloy that contains at least 10.5% chromium. There is a wide variety of alloys available on the market, each differing in exact chemical composition. Alloying elements such as nickel, molybdenum, carbon, nitrogen, titanium and copper can improve the durability, formability and other properties of ​316 steel pipe​.

In order to qualify as steel, it must meet the requirements for corrosion resistance in a given environment. This resistance arises from the outer layer of metal chromium oxide. This microscopic surface layer is known as a passive layer because it naturally interacts with the oxygen in the surrounding air and prevents further corrosion. In addition, if the layer has damage such as scratches, it can be repaired on its own.

What are the useful properties of steel?

Obviously, the main feature of steel is its resistance to corrosion. Different alloys offer different levels of resistance. For example, ​food grade steel pipe​, probably the most popular steel alloy in the world, provides an excellent level of corrosion resistance. However, when it comes to the marine environment, 304 is not well suited as it is particularly susceptible to chloride exposure, which is definitely present in seawater. Instead, an application in a marine environment should probably switch to 316 steel fittings, which have the added benefit of 2% molybdenum.

Steel has other advantages. Compared with ordinary steel, alloy steels are used in various stainless steel pipe fittings in various industries

It includes a number of applications exclusively for ​decorative steel pipe​ that take advantage of the metal's highly desirable properties.

By definition, ​321 steel pipe​ is an iron alloy that contains at least 10.5% chromium. There is a wide variety of alloys available on the market, each differing in exact chemical composition.

Steel has other advantages. Compared to ordinary steel, stainless steel alloys offer improved cold strength, increased work toughness, increased strength and durability, increased formability, more attractive appearance, and lower maintenance costs. With all of this happening, it's no wonder that steel is so common in a wide range of industries, including pipe fittings.

Since each alloy behaves differently, it is important to be able to distinguish between them. Steel alloys are classified into five different families, each of which is distinguished by its own characteristics. The five families are austenitic, ferritic, martensitic, duplex and precipitation hardening.

What are the uses of steel for pipe fittings?

The advantages of corrosion-resistant metal when it comes to pipe fittings should be obvious. This is why steel is a popular choice for pipe fitting applications. Pipe fittings come in many different shapes and sizes.

SS 304 pipe fittings are one of the most common pipe fittings. This is due to its corrosion resistance and other advantages. 304 also offers strong chemical resistance, an added bonus for materials exposed to large amounts of water, especially in industrial environments.

One of the special applications for pipe fittings is steel pressure pipe ​316 steel fittings​.
