What is Type 304 Stainless Steel?

304 stainless steel is a versatile and dexterous stainless steel. It is the most widely used stainless steel grade around the world. It is a widely used material across a number of industries, as a result of the ease in which it can be formed into a vast number of shapes. Sectors using 304 stainless steel include:

  • Food processing - across the food industry, strong and non-corrosive equipment is of paramount importance. 304 stainless steel exhibits superb anti-corrosion properties, and as a result, is suitable for the processing and handling of most food products. 

  • Chemical industry - stainless steel demonstrates a number of properties that are advantageous in chemical applications. For example, it is resistant to corrosion and heat.

304 stainless steel is:

  • Easy to form, weld and fabricate,
  • Durable
  • Anti-corrosive
  • Anti-rust
As a result, it a suitable material for a number of applications. Make an enquiry to discuss your requirements.

What is the difference between 304 vs 304L stainless steel?

Stainless steel grades 304 and 304L are the most basic stainless steel products.

304 and 304L have similar properties, however 304L has a lower carbon content. This lower carbon content results in improved weldability and a lower risk of reduced corrosion resistance around the weld. It should also be noted that 304L also demonstrates a slightly lower yield and tensile strength than 304.

SAE specifications define 304 and 304L as part of the 300 Series of Steels (this category covers a range of austenitic chromium-nickel alloys).
