304 stainless steel is one of the most flexible and commonly used stainless steels on the market. 304 stainless steel is the most commercially used stainless steel alloy of its kind. SS304 is basically an austenitic chromium alloy, also known as "18/8" stainless steel because the steel composition is 18% chromium and 8% nickel.

       However, 304 stainless steel is susceptible to corrosion by chloride substitutes. Pitting or cracking can be caused by chloride ions, which essentially localize areas of corrosion. Under the chromium oxide barrier, these degraded parts can spread to internal components. For example, for SS304 coils, high-salt environments such as outdoor coastal areas or cold, icy areas with frequent exposure to de-icing salts may not be suitable. Using chemicals, especially chloride solutions, to create atmospheres or other commercial applications can also cause problems with products and equipment.


       Characteristics of 304 stainless steel pipes


       Excellent weldability

       304 stainless steel has excellent welding properties. When welding thin sheets, post-weld annealing is not required. Stainless steel 304 has excellent weldability and is suitable for all standard fusion processes, with or without filler metal. Welding heavy sections of stainless steel 304 may require post-weld annealing for maximum corrosion resistance.

       heat treatment

       During solution treatment (annealing), 304 stainless steel can be heated to 1010-1120 degrees Celsius and then rapidly cooled. These grades cannot be hardened by heat treatment. Heat treatment is a very important process in manufacturing stainless steel pipes. Heat treatment is critical to the high strength and durability of 304 stainless steel pipe.

       Machining

       The enhanced machinability version "Ugima" of grade 304 for bar products "Ugima" machines is a significant improvement over the standard 304, resulting in higher machining rates and lower tool wear in many processes.


       Application of grade 304 stainless steel pipe

       Stainless steel 304 seamless pipes are used in various fields, especially food processing, because they are not prone to acid corrosion found in ordinary foods. Therefore, this steel is suitable for products such as sinks, dishwashers, commercial food processing equipment, and refrigerators. Stainless steel 304 pipe is also used in heat exchangers, chemical vessels and piping throughout the brewing industry. It can be used as a manufacturing material for storing high-temperature petroleum gas or steam (such as pressure vessels). Stainless steel 304 pipe can also be used in structures in environments that corrode standard carbon steel.
