Stainless steel 304 is a majorly used grade of stainless steel that is in high demand in market due to its great resourcefulness. It is an alloy comprising of Chromium and Nickel and is also known as “18/8” stainless since it contains 18% chromium and 8% nickel. The chromium in the alloy enhances its resistance to corrosion and oxidation. The steel has high strength under extreme pressure and temperature but it needs to be cold worked to generate higher tensile strength. The stainless steel 304 alloy has the ability to show resistance against most oxidizing acids and will withstand ordinary rusting, but it would get tarnished over the years.


The Stainless Steel 304 pipes are extremely strong products that can sustain even under extreme pressure and temperature. These pipes have excellent forming and welding characteristics. Due to the austenitic structure, stainless steel 304 pipes possess excellent toughness and strength even at cryogenic temperatures. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields.

Stainless Steel 304 pipes are majorly used in Food processing equipments, particularly for beer brewing, wine making, and milk processing. It is also used in heat exchangers and chemical containers. Because of the balanced austenitic structure of stainless steel 304, they have been very useful in manufacturing drawn stainless parts such as sinks, hollow-ware, and saucepans. Stainless steel 304 pipes have also shown usefulness in Pharmaceutical industry and for cosmetic purposes.
