All You Need To Know About Stainless Steel 304 Pipes and Tubes

Stainless Steel 304 is one of the most flexible and commonly used stainless steels on the market, and 304 Stainless Steel is the most commercially used stainless steel alloy of its kind. SS 304 is basically an austenitic chromium alloy that is also known as “18/8” stainless as the steel composition is 18 percent chromium and 8 percent nickel.

304 stainless steel, however, is vulnerable to corrosion by chloride alternatives. Pitting or cracking can be caused by chloride ions, which are essentially localized corrosion regions. Under chromium oxide barriers, these degraded parts can spread to degrade internal components. For e.g. In the case of  SS 304 Coil, high saline surroundings such as outdoor coastal areas or cold, icy regions which are constantly exposed to de-icing salts might not be appropriate. Manufacturing atmospheres or other business applications using chemicals — especially chloride solutions— might also cause problems for products and equipment.

Characteristics of SS 304 Pipes

Excellent Weldability

SS 304 has outstanding welding characteristics. When welding thin sections it does not require post-weld annealing. SS 304 has outstanding weldability for all standard fusion processes, with or without filler metals. Welding heavy sections of SS 304 may require post-weld annealing for maximum resistance to corrosion.

Heat Treatment

During Solution Treatment (Annealing) Stainless Steel 304 can be heated to 1010-1120 degrees C and is then cooled rapidly. These grades cannot be hardened by thermal treatment. Heat treatment is a quite important process for the manufacture of stainless steel pipes Heat treatment is critical for creating high strength and durability in stainless steel 304 Tubes.


Grade 304 enhanced machinability version “Ugima” is available in bar products “Ugima” machines significantly improved than standard 304, resulting in higher machining rates and lower tool wear in many processes.

Applications of Grade 304 Stainless Steel Tubes

Stainless Steel 304 Seamless Pipes are used in various fields, especially food processing, as they are not prone to acid corrosion found in common foods. This steel is therefore suitable for products such as sinks, dishwashers, Commercial food processing equipment, and refrigerators.  SS 304 Pipes can also be used in heat exchangers, chemical containers and pipes throughout the brewing industry. It can be used as a manufactured material where high-temperature petroleum gasses or vapors, such as pressure vessels, are stored. SS 304 Tubes can also be used in structures in environments that would corrode standard carbon steel.
