304 Grade Stainless Steel

Definition - What does 304 Grade Stainless Steel mean?

304 grade stainless steel is known to be the most widely used and flexible austenitic form of stainless steel. It contains 8% nickel and 18% chromium, making it ultra resistant to corrosion and oxidation.

It is also highly durable and can be fabricated with ease. Cleaning the metal is also easy, and it is available in various appearances and finishes.

Corrosionpedia explains 304 Grade Stainless Steel

Grade 304 stainless steel is an outstanding metal for:

  • Auto trim and molding
  • Kitchen equipment
  • Wheel covers
  • Truck bodies
  • Exhaust manifolds
  • Storage tanks
  • Pressure piping and vessels

The percentage of nickel and chromium that is present in 304 stainless steel equips this metal with good corrosion resistance, particularly to moderately caustic and acidic solutions. It also performs in a similar way in almost all non-severe conditions, except in welding. In such cases, stainless steel 304L is ideal, as it offers more resistance to intergranular corrosion.

More specific usages include the production of dairy equipment like sterilizers, milking machines, hauling tanks, milk trucks, piping valves and more. It is also highly beneficial in certain applications such as food processing. Packing houses, bakeries, mills, slaughter houses and other parts that are exposed to vegetable or animal oils as well as acids are usually made from 304 stainless steel.
