304 or 316 Stainless Steel Nipples

The 300 series of stainless steel includes; 301, 302, 304, 310, 316, 317, etc., and covers a variety of applications. While some are suited better for high temperatures (the H designation), others are low carbon (with an L). The most popular and widely used is 304 stainless steel. We manufacture and sell 304 or 316 stainless steel nipples to our clients. Due to recent capacity increases, we can produce sizes of 4″ to 12″ using 304 or 316 stainless.

Grade 304 is an austenitic chromium alloy also known as “18-8” because it is made up of 18 percent chromium and 8 percent nickel stainless. If there is no nickel, you have 400 stainless, which is magnetic and even less corrosion resistant. However, the 304 & 316 are not magnetic. Check out some of our other articles, if you want to know more about stainless steel. But, what is the difference between 304 and 316 nipples?


316 Stainless Steel

While both grades have chromium and nickel, the 316-grade nipples have molybdenum. Molybdenum is an alloy that increases corrosion resistance, especially against chloride and other industrial solvents. As a result, 316 stainless steel is often seen in applications such as kitchen sinks, ovens, etc. Stainless Steel with 316-grade alloys is excellent for connections and tubing. Also, 316H grade is made to withstand higher temperatures. Unlike 316 & 316L it isn’t stocked with dual certification.

Some common uses of 316-grade steel are: 

  • Industrial Equipment
  • Marine Equipment
  • Medical Equipment
  • Commercial Kitchens
  • Pressure Valves

304 Stainless Steel

304 stainless only has trace amounts of molybdenum which makes it less corrosion-resistant than 316. The popularity of the 304 relates directly to its ease of welding and fabrication. The 316 austenitic stainless steel is regarded as second in importance to the 304 grade but is also great for welding. The 304L and 316L both contain low carbon making them better options for applications that require welding. Some common uses of 304-grade steel are:

  • Storage Tanks
  • Pots and Pans
  • Residential Appliances
  • Fasteners and Finishing Hardware
  • Equipment Tubing 

Regardless if you are looking for 304 or 316 nipples, Detroit Nipple Works has you covered! 

304 or 316 Stainless Steel Nipples

Grade Stainless Steel Nipples

As we said, Detroit Nipple Works primarily uses 304 or 316 stainless for manufacturing nipples in this material. While we produce nipples using other types of steel pipe, stainless is the most popular. Your choice between 304 and 316 nipples depends on the application. Whereas, many industries use 316 nipples for surgical equipment and pharmaceutical equipment, and so on. 316 or 316L are the best choices for stainless steel nipples in chloride environments as you will have less pitting and acid-based corrosion.
