Type 304H has a higher Carbon content making the steel more suitable for use in applications where elevated temperatures are present. It is an austentic chromium-nickel steel alloy and the greater carbon content delivery an increased tensile and yied strenght.

The material is recommended for use in ASME Pressure vessels in working service above 525 Deg-C due to the greades's heat resistant properties.

Benefits of using 304H Stainless teel
>Higher carbon content gives the material greater heat resistant qualities.
>Higher Tensile yield strength
>Greater short and long term creep strength

304H alloy is commonly found in the oil refining,gas and chemical industrial boiler,pressure vessels. heat-exchangers,pipelines and condensers, The material is also used throughout the power generation industry.

Applications of Grade 304H 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 304H 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.

304H 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.

304H 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.

304H 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.
