Chemical, Processing and Oil & Gas industries

Stainless Steel Applications : Probably the most demanding industries that use stainless steels are the chemical, processing and oil & gas industries have created a large market for stainless tanks, pipes, pumps and valves as well. Special grades of stainless have been developed to have greater corrosion resistance at a broad range of different temperatures. These are used in desalination plants, sewage plants, offshore oil rigs, harbor supports and ships propellers.

Food Processing Industries

Stainless Steel Applications : Another industry where stainless steel products are used is food processing. From tools to surfaces, this metal is highly suitable for production, processing, and packaging.Stainless steel machinability and other properties make it a great option for food processing, as well as a multitude of other industries.

Pharmaceutical Industries

Stainless Steel Applications : Stainless steels are widely used in the pharmaceuticals industry because of their resistance to corrosion, inert (easily cleaned) surfaces and ease of fabrication. Although grade 1.4401 (AISI 316) and its derivatives are the most widely used stainless steels in pharmaceutical plant and are considered by many as the industry standard, materials for each application are selected on the basis of their resistance to corrosion in a specific service environment. The selection of a suitable grade of stainless steel must also include consideration of the cleaning regime and cleaning agents used in the plant.

Railways

Stainless Steel Applications : Materials for railway applications are required to maintain the integrity of the structure
(i.e. to be sufficiently robust to withstand their service environment) and to be inert (ie
corrosion resistant). Stainless steels are used in railway applications because they
are resistant to corrosion, easily fabricated and offer good mechanical properties.
The following examples may serve to indicate the considerations made in selecting a
suitable grade of stainless steel for railway applications. Austenitic stainless steel
grades 1.4301 (AISI 304) and 1.4310 (AISI 301) are suitable for mild service
environments and have been used in the construction of railway carriages, while
ferritic stainless steel 1.4003 (ASTM S41050) has been used for freight wagons.
Stainless steel is selected for both applications because it does not need protective
paint coatings and thus maintenance costs are reduced.

Pulp & Paper Industries

Stainless Steel Applications : The two main reasons for the use of stainless steels and, on occasion, nickel alloys and other metals in the Pulp and Paper Industry is to avoid iron contamination of the product and to resist process corrosion. Although most mills use nominally the same sulfate kraft or sulphite process, there are sufficient mill-to-mill difference that can affect corrosion behavior .

Medical Applications of Stainless Steel (Surgical)

Stainless Steel Applications : A high corrosion resistance and low carbon content are key factors that mak Stainless Steel 304 suitable for medical applications over and above other grades of Stainless steel. The reassurance that medical devices won’t chemically react with bodily tissue, cleaning products used to sterilise and the hard, reptitive wear that many medical devices are subjected to, means that Stainless 304 is the perfect material for hospitals, surgeries and paramedic applications etc.

Nuclear Power Plants & Steel Plants

Stainless Steel Applications : Neutron irradiation inside a Nuclear Power Plant can put even the strongest of metals to test. Unlike a lot of other metals, Stainless Steel has the strength to provide greater safety and superior performance expected from the structural components of pressurised water reactors and fast breeder reactors due to its superior strength-to-weight ratio, corrosion resistance, high ductility and durability. But that’s not all, stainless steel is also the material of choice for reprocessing spent fuel discharge from reactors. At Jindal Stainless, we are proud to strengthen India’s journey towards clean and green energy by supplying 304L (NAG)/304/304L/304LN/316/316L/316LN/321/310S and EN 1.4550 stainless steel to the nuclear sector.

Architecture, building and construction

Stainless Steel Applications : Architecture, building and construction is a growing market as many modern buildings use stainless steels for cladding, roofing and facades. Another thing is that the low maintenance cost and anti-vandal characteristics of stainless provides a growing market in public transport, ticket machines and street furniture. Stainless steels are used for construction purposes, as well. When reinforced concrete first started to be used it was considered that the carbon steel used would not rust, as cement, obviously derived from limestone, is alkaline. However, constantly using grit salt on bridges can change the pH to acidic thereby rusting the steel which expands and cracks the concrete. Stainless steel reinforcing bar, although initially expensive, is proving to have very good life cycle costing characteristics.

Automotive

Stainless Steel Applications : Cars are making increasing use of stainless steel, primarily for exhaust systems (grade 409) and catalytic converters, but also for structural purposes. With greater attention being made to achieving low long term maintenance costs, less environmental impact and greater concern with life cycle costs, the market for stainless steel continues to improve.

Other Stainless Steel Applications :

  • Offshore technology
  • Seawater desalination plants
  • Chemical industry
  • Bridges
  • Storage tanks
  • Medical Industry
  • Civil Engineering
  • Pressure vessels, reactor tanks, and heat exchanger
  • Rotors, impellers and shafts
  • Power plants
  • Petrochemical
  • Shipbuilding industry

Mining and Minerals

Stainless Steel Applications : Mining is the process of extracting materials from the earth. The materials covered are usually in the form of metals both common and precious and it’s something that has been done for thousands of years to acquire beneficial resources. The mining industry is one where stainless steel has made it easier and more profitable to take on larger operations. Whether it’s used in the actual mines itself where workers and machines dig at the earth, or in the bunk beds and mess halls where staff sleep, it’s used in a variety of different applications to provide safety and reliability.
