Is Stainless Steel Ferrous or Non-Ferrous?

As scrappers, we all know how crucial a role metals play in modern industries, from construction and manufacturing to technology and healthcare. But when it comes to stainless steel, you have to wonder: Is it ferrous or non-ferrous? It can be non-magnetic (like all non-ferrous metals) but is also mostly iron (the prerequisite for ferrous metals). While stainless steel does contain iron, its unique properties blur the lines between traditional classifications.

Understanding where stainless steel falls in the ferrous vs. non-ferrous debate is essential for scrappers, buyers, and anyone dealing with metal. Plus, if you want to sell scrap stainless steel, using the iScrap App can help you find the best prices at nearby yards.

Why Is Stainless Steel Considered a Ferrous Metal?

Stainless steel shares traits with ferrous and non-ferrous metals but is classified as ferrous because it contains iron. Typically, most types of stainless steel are around 70% iron, which places them in this category.

However, unlike traditional ferrous metals, stainless steel resists rust and corrosion due to the other metals present in its chemical makeup. As a result, many common stainless steel forms are non-magnetic.

  • Contains iron → Ferrous classification
  • Chromium (at least 10.5%) → Prevents rust.
  • It may contain nickel and molybdenum → Enhances strength and corrosion resistance.

What Are Ferrous Metals?

Ferrous metals contain iron as their main component. Due to their strength and durability, they are widely used in construction, manufacturing, and industrial applications.

Common Ferrous Metals:

What Are Non-Ferrous Metals?

Non-ferrous metals lack significant iron content, making them resistant to rust and corrosion. These metals are often used for electrical wiring, plumbing, and lightweight structural applications. They are typically lightweight and, most importantly, non-magnetic. Due to this, they are also more valuable when sold.

Common Non-Ferrous Metals:

Types of Stainless Steel and Their Properties

  • Austenitic Stainless Steels (e.g., 304, 316): Highly corrosion-resistant, non-magnetic.
  • Ferritic & Martensitic Stainless Steels: Magnetic, often used in industrial applications.

Selling Scrap Stainless Steel

Scrap stainless steel has value, but the price depends on its grade. Stainless steel with higher nickel and molybdenum content (e.g., 316 stainless) is more valuable than the more common 304 stainless steel. Some tips to keep in mind include:

  • Scrap yards often classify stainless steel separately from regular ferrous metals.
  • Non-magnetic grades (304, 316) are often categorized differently from standard ferrous materials.
  • In the scrap industry, stainless steel is sometimes treated as non-ferrous because it doesn’t rust like regular ferrous metals and has different properties due to its chromium and nickel content.

Find Scrap Stainless Steel Prices with the iScrap App

If you’re looking to scrap stainless steel, the iScrap App is your go-to tool for finding the best prices at local scrap yards. With real-time price updates, you can compare rates for different grades of stainless steel, including non-magnetic varieties like 304 and 316, which often fetch higher prices. The app also helps you locate nearby scrap yards that accept stainless steel and other metals, ensuring you get the best deal possible.
