Stainless Steel Enclosures: 304 vs 316


304 vs 316 Stainless Steel

In this video you will learn:

  1. Which enclosure is best in resisting chemical  exposure
  2. The ideal enclosure for welding, if you need to make any modifications to your enclosure
  3. The stainless steel idea for salt exposure for environments near the ocean, or near de-icing salts
  4. The enemy of stainless steel


[0m:4s] Hi I'm Josh Bloom, welcome to another video in the RSP Supply education series. Today we're going to be talking about the differences between 304 stainless steel enclosures and 316 stainless steel enclosures. Let's start with 304 stainless steel, also known as 18 8 stainless steel, named for its 18% Chromium content and 8% nickel content.
[0m:25s] This is the most widely and commonly used stainless steel within the industrial industry. 304 stainless steel has very good corrosion resistance, properties in most applications.
[0m:33s] It does do a very good job of resisting oxidizing acids which can cause rusting, however, it can tarnish.
[0m:40s] 304 stainless steel is a more economical stainless steel choice.
[0m:44s] Is also very durable and strong and can be bent without decreasing the strength of the stainless steel. However, it is a very strong hard metal and can be difficult to manipulate.
[0m:54s] 304 stainless steel is ideal for welding, so if you need to make any modifications to your enclosure it's a great material for that purpose. Because of its corrosive resistance you'll find that 304 stainless steel enclosures are commonly used in dairy plants,
[1m:6s] mills, bakeries, and any type of food processing industries.
[1m:11s] Now let's talk about 316 stainless steel. This is a much higher grade of stainless steel has a 16% Chromium content has 10% nickel content much like the 304 stainless steel.
The main difference is it has a 2% molybdenum content which significantly increases its resistance to pitting and cracking.
[1m:28s] It also has increased corrosive resistance properties specifically, but not limited to chloride pollutants such as salt.
[1m:35s] 316 Stein Stiles steel enclosures are going to be more ideal for areas where we have a high salt content, such as coastal areas where we have sea sprays, also areas where we use Deicing salts or rain water salts.
[1m:47s] This type of stainless steel is much more resistant to chemical environments that include Suphuric or phosphoric acid or many other chemicals. These types of stainless steel enclosures are going to be commonly found in areas with high levels of corrosive agents that you might find in water, wastewater, chemical plants, fertilizer plants, et cetera. Both 304 and 316 stainless steel enclosures are NEMA 4X rated due to their corrosion resistance. It's important to remember that we never use any chemicals that contain chlorine. Chlorine is going to be an enemy of stainless steel. So this is going to include any cleaners or detergents that contain that product.
