what’s the difference between stainless steel and brass material

stainless steel VS brass

Stainless Steel material

While a more expensive option than brass, steel is a very durable, resilient metal. While brass is a copper alloy, stainless steel is an iron alloy mixed with chromium and nickel.

The nature of the material means that these valves are able to effectively resist leaks. Steel is also able to work in more temperatures than brass and tends to last longer. Stainless steel valves are the best options for high pressure and temperature situations. They are also a great material for corrosion resistance.

Stainless steel 316, is especially corrosion resistant because it has more nickel and also contains molybdenum. This combination of iron, nickel and molybdenum make the valves especially resistant to chlorides and very useful in marine environments.


Brass material

Brass is a copper alloy which means that it is stronger than plastic. This additional strength makes them, though not the most expensive option for valve, more expensive than PVC or plastic valves.

Brass is a mixture of copper and zinc, and occasionally other metals. Because of its nature as a soft metal, it is able to resist corrosion very well as opposed to plastic valves.

Brass products contain small amounts of lead. Most of the time brass products are made up of less than 2% lead, however this causes some skepticism for many. In fact, the FDA does not approve of brass valves being used unless they are certified lead-free. Use discretion when choosing the valve material for your next project.


The Difference between stainless steel and brass

This comparison of stainless steel valves and brass valves has provided us a number of significant differences to consider.

Cost: Stainless steel valves are more expensive than brass valves. If both materials will meet the needs of your project and budget is a concern, consider using brass valves to save on money.

FDA Approval: The FDA does not approve of brass valves unless they are certified lead-free, making them a poor choice for use in the food industry. Stainless steel, however, is approved by the FDA for use in the industry.

Corrosion Resistance: Brass is able to withstand corrosion better than plastic. However, stainless steel is still the best in the corrosion resistance department, especially in marine environments.
