Understanding 304 Stainless Steel: Composition, Properties, and Uses

304 stainless steel is a widely used, non-magnetic, and corrosion-resistant metal alloy composed mainly of iron, chromium, nickel, and small amounts of carbon. It is the most common type of stainless steel, valued for its versatility and durability in various applications, from kitchenware to industrial equipment.

Composition of 304 Stainless Steel

Often referred to as 18/8 stainless steel, 304 contains approximately 18% chromium and 8% nickel. Additionally, it includes trace amounts of carbon, manganese, silicon, phosphorus, and sulfur.

There are also variations of 304 stainless steel:

  • 304L – A low-carbon variant that improves weldability.
  • 304H – A high-carbon version designed for use in elevated-temperature environments.

Key Properties of 304 Stainless Steel

  • Resistant to corrosion, water, and many chemicals.
  • Non-magnetic and highly durable.
  • Easily shaped and formed into different structures.
  • Lower electrical and thermal conductivity compared to carbon steel.
