Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy.

Grade 304 is the standard “18/8” stainless that you will probably see in your pans and cookery tools. These are some of its characteristics:

• Forming and welding properties
• Corrosion/ oxidation resistance thanks to the chromium content
• Deep drawing quality
• Excellent toughness, even down to cryonegic temperatures which are defined as very low temperatures
• Low temperature properties responding well to hardening by cold working
• Ease of cleaning, ease of fabrication, beauty of appearance

A stainless steel 304 nipple manufactured at INSTINOX is a fitting, consisting of a short piece of pipe, usually provided with a male pipe thread at each end, for connecting two other fittings. The length of the nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for wrench to grasp (sometimes referred to as a “hex nipple”), or it may simply be made from a short piece of pipe (sometimes referred to as a “barrel nipple” or “pipe nipple”). The length of the nipple is usually specified by the overall length with threads. It may have a hex section in the center for wrench to grasp. A “close nipple” has no unthreaded area; when screwed tightly between two female fittings, very little of the nipple remains exposed. A close nipple can only be unscrewed by gripping one threaded end with a pipe wrench which will damage the threads[citation needed] and necessitate replacing the nipple, or by using a specialty tool known as a nipple wrench (or known as an internal pipe wrench) which grips the inside of the pipe, leaving the threads undamaged. When the ends are of two different sizes it is called a reducer or unequal nipple. A barrel nipple or a pipe nipple is one which is usually made from pipe and is threaded only at both ends.
A stainless steel 304 pipe nipple is a protective sleeve that includes a sheath that is closed at a forward end and connects to a collar at an open rear end. On the other hand a Pipe reducer joins two pipes of different diameter. That is both pipe nipples and pipe reducers are not same. A pipe nipple is a manufactured piece of pipe that is threaded on both ends. A pipe reducer changes the size of pipe from one section to another. A reducer coupling has female threads on both ends and a reducer bushing has male threads on one end and female threads on the other.
The working pressure of pipe nipples will vary with the size and construction of the pipe, the type and number of clamps used, clamp placement, proper installation of clamps, temperature and product being conveyed. Pipe nipples are available in the widest variety of wall thicknesses and materials in the industry.
