One of the most versatile and commonly used stainless steels on the market, Grade 304 stainless steel is the most standard used alloy of this type. Essentially, Grade 304 is an austenitic chromium alloy which is also known as an "18/8" stainless as the make-up of the steel is 18% chromium and 8% nickel.
The chromium content promotes the material's considerable resistance to the effects of corrosion and oxidation. The stainless steel alloy resists most oxidizing acids and will withstand ordinary rusting though this does not mean that the steel will not tarnish over time. The steel needs to be cold worked to generate higher tensile strength. For stainless steel sections which are welded heavily, post-weld annealing may be necessary to provide maximum corrosive resistance.

Applications of Grade 304 Stainless Steel
The steel is common throughout industry particularly in food processing as the material is not susceptible to corrosion from acids found in common foodstuffs. As a consequence, such steel is ideal for items such as sinks, work surfaces, preparation areas and refrigerators. It is also a perfect material for use in the pharmaceutical industry for environments such as clean rooms.
Grade 304 can also be found in heat exchangers, chemical containers, pipelines and throughout the brewing industry. It can be used as a fabricated material where high temperature petroleum gases or steam production gases are stored such as pressure vessels. It can even be found extensively in the construction industry where the material is used for cosmetic purposes such as building fascias.
304&304L plate and Pipe have similar properties and in certain cases are stocked with Dual Certification, where it is concluded that each item has properties and a composition which comply with both steel types. Grade 304H cannot be included in this equation due to the steel's higher carbon content which is intended for use in elevated temperature applications.

304 Stainless Steel Pipe and Tubes Corrosion Resistance
Excellent in a wide range of atmospheric environments and many corrosive media. Subject to pitting and crevice corrosion in warm chloride environments, and to stress corrosion cracking above about 60 Deg-C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60 Deg-C.
304 Stainless Steel Pipe and Tubes Heat Resistance
Good oxidation resistance in intermittent service to 870 Deg-C and in continuous service to 925 Deg-C. Continuous use of 304 in the 425-860 Deg-C range is not recommended if subsequent aqueous corrosion resistance is important. Grade 304L is more resistant to carbide precipitation and can be heated into the above temperature range.
Grade 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 500 Deg-C and up to about 800 Deg-C. 304H will become sensitised in the temperature range of 425-860 Deg-C; this is not a problem for high temperature applications, but will result in reduced aqueous corrosion resistance.
304 Stainless Steel Pipe and Tubes Heat Treatment
Solution Treatment (Annealing) Heat to 1010-1120 Deg-C and cool rapidly. These grades cannot be hardened by thermal treatment.
304 Stainless Steel Pipe and Tubes Packing
304 Stainless steel seamless pipes and tubes is sleeved into plastic bag individually, pieces wrapped with water-proof material ,bundled with nylon rope.Clear labes are tagged on the outside of the package for easy identification of the quantity and products I.D. Great Care is taken during operation and transportaion.
SS304 ASTM A312 Seamless pipe packing will be according to international standard in bundles strapped by strips then into containers to avoid any damage.
