Valuable Information About Stainless Steel Fittings

The manufacture of stainless steel fittings has created a revolution in the plumbing industry. Long before using stainless steel, building owners used mild steel, plastic pipes, and copper tubes for hydraulic and fire protection systems.

Before purchasing the fittings, you must know the quality, durability, and other features of stainless steel. This article may provide you with some important information about stainless steel products.

Fitting applications

You can utilize the fittings of stainless steel in several applications.

  • You can use these fittings in highly corrosive and sanitary applications in industrial projects.
  • In commercial and residential water systems where are various stresses, these fittings are suitable to use.
  • You can use the stainless steel fittings in commercial and industrial piping systems as they can work under pressure and harsh conditions.
  • There are some common applications like couplings, caps, elbows, locknuts, bushings, plugs, and bulbs where you can find the usage of stainless steel.

Stainless steel grades

The grade numbers signify the composition of chromium and nickel in stainless steel. The two most common stainless steel grades are Stainless 304 and 316. You can find their usage in various domestic and commercial applications.

Stainless steel 304

This type of stainless steel grade is a good resistant to atmospheric corrosion, and organic and inorganic chemicals. It consists minimum of 18% Chromium and 8% Nickel. Stainless steel 304 has outstanding strength, workability, and weldability.

It is suitable to use in numerous applications such as kitchen equipment, stainless steel fittings, stainless hardware, pressure vessels, piping, and more. Grade 304 is so common that 60% of usable stainless steel includes this grade.

Stainless steel 316

Stainless steel 316 is better resistant than grade 304 in many chemical solutions and marine atmospheres. This feature makes this steel known as a marine alloy.

You can find the applications of this grade in the paper, textile and chemical industries. It also has non-reactive qualities that make its effective use in the manufacture of medical surgical equipment stainless steel 316 has a similar strength to stainless steel 304, but it performs better in deep drawing.

Stainless steel turnings

It comprises clean stainless steel that contains a minimum of 16% Chromium and 7% Nickel. It does not include excessive iron, nonmetallic, non-ferrous metal, oil, and other impurities.

Ways to dispose of steel products

  • Make sure that your products including stainless steel fittings are containing at least 50% of metal.
  • If your product contains a mixture of stainless steel and other material like plastic or fabric, you can separate the steel part from the others.
  • You have to identify if the product is ferrous or non-ferrous. You can use a magnet to detect a ferrous product as it sticks to the magnet.
  • You can contact the recyclers from your locality to perform the task.


The usage of mechanical press-fit and roll groove systems for all piping systems has offered a major market for stainless steel. The stainless steel fittings for pipes are very effective in solving issues including high-pressure requirements, and a corrosive environment for the water service system.
