What is Stainless Steel ?

Stainless steel is an alloy that is made up of iron and generally contains around 11.5% chromium. The addition of chromium allows the alloy to form a protective self-healing oxide film, thereby making them resistant to corrosion and oxidation even at extremely high temperatures. Due to this feature, stainless steel is used for making products across many fields. For obtaining special properties, nickel and other elements can be added to this alloy.

The alloys that make up the family of stainless steels were initially discovered in the year 1913 in Sheffield, England, when Harry Brearley was trying to make a combination of various alloys for gun barrel steels, and he noticed that samples that were cut from one of these trial heats did not rust and were, in fact, difficult to etch.

Various types or grades of Stainless steel are available as per different needs. These grades differ from each other by a few components. All of the grades, type 304 stainless steel is the most commonly used material which has application in making corrosive resistant pipes, in chemical plants, refineries, paper mills, and food processing industries. Similar to type 304, is another grade known as type 304L. The two are almost the same, except that 304L has 0.03% more carbon content.

The grade called as Type 318 is even better at protecting materials from pitting than other chromium-nickel alloys. It is because it contains 2% to 3% molybdenum. This grade is highly useful at places where acids, sulphur water, seawater or halogen salts are encountered.

Type 316 of Stainless steel is highly valuable and is used in the sulphite paper industry and for manufacturing chemical plant apparatus, photographic equipment, and plastics. Similar to Type 304L, type 316L holds a maximum carbon content of 0.03%. Due to this, it is used in welded assemblies without the need of final heat treatment.

Stainless steel is popular due to its excellent favourable properties such as:
    • Excellent resistance to corrosion- The excellent capability of stainless steel to provide more resistance towards oxidation by water and biocide results in a longer lifetime.
    • Protection against Corrosion- Stainless steel does not need to have an internal and external coating or cathodic protection. As a result, system costs are highly reduced and it is more compatible with the environment.
    • Hygienic material- It is highly inert in water because of its very high passive film stability. This makes leaching of alloying elements (Cr and Ni) possible within safe limits and a result, they provide a better quality of drinking water.
    • Good strength and ductility – Stainless steel is much stronger and has higher mechanical properties when compared to carbon steel and cast iron pipes. Due to this, there is the reduction in the wall thickness of the pipe and in turn it reduces investment costs.
    • Ease of fabrication – Stainless steel is a highly adaptable material with ease of forming, machining and welding, combined with their good ductility that allows pipelines to be easily installed and modified.
    • Ease of maintenance – Stainless steel has high corrosion resistance and easy welding capability, thereby reducing water leaks drastically. This, in turn, results in higher cost savings.
    • Excellent durability – Due to its resistance to crevice corrosion and cavitation, Stainless steel wears off less in pure and polluted waters and even in the atmosphere. It is thus convenient and cost friendly material for long term use and is even eco-friendly.
    • Recyclable – Stainless steel can be easily recycled up to a 100% and a part of their initial cost can be recovered due to this process.

Due to an extremely high consumption of stainless steel all over the world, its demand is ever increasing. It is required in multiple industries including building and construction industry where stainless steel is used for its attractive appearance, corrosion resistance, low maintenance, and strength. Stainless steel does not need to be treated, coated or painted when put into service. Various other industries are considering using stainless steel for similar reasons as due to its low maintenance requirements.

Manufacturing Steel Tube Fittings is a critical process as it consists of a four piece unit:

      • Nuts
      • Body
      • Front Ferrule
      • Back Ferrule

They are assembled to a tube to form a leak-free connection.

Ferrules are the heart of Steel Tube Fittings. They are responsible for any pressure the fitting is able to contain. Our Engineers have developed consistent technology for manufacturing ferrules that sustain the highest pressure.

Stainless Steel Tube Fittings come in the following connections

Introduction about Stainless Steel Tube Fittings

Steel Tube Fittings are products that are used to connect, mount and configure other products. They are typically used to connect runs of tubing for in-line, offset, multi-port, and mounting configurations to other tubing sections, pipe, hose, and other fluid transfer components. They are designed for instrumentation and process applications where leak-tight performance is critical to quality and productivity.

Steel Tube Fittings are mainly used for various domestic purposes such as in kitchen utensils, cutlery, sinks, machine drums and microwave oven liners. It is used in civil engineering for making fittings for doors and windows, street furniture, structural sections, reinforcement bar and lighting columns. In Transport systems, it is used for making exhaust systems, car grilles, road tankers, ship containers and ships chemical tankers. The chemical industry makes use of Stainless Steel Tube Fittings in making pressure vessels, for process piping and for making platform accommodation, cable trays and sub-sea pipelines in Oil and Gas industry. They are also used for making surgical instruments, surgical implants, MRI scanners, catering equipment, brewing, distilling, and food processing systems. Other uses of stainless steel include manufacturing pipes in water and sewage treatment, water tubing, hot water tanks and fasteners.
