304/304L/304H stainless steel

304 Stainless Steel

Stainless steel 304 is an austenitic grade that can be severely deep drawn. This property has resulted

in 304 being the dominant grade used in applications like sinks and saucepans.


304L Stainless Steel

Type 304L is the low carbon version of Stainless steel 304. It is used in heavy gauge components for improved weldability. Some products such as plate and pipe may be available as "dual certified" material that meets the criteria for both 304 and 304L.


304H Stainless Steel

304H, a high carbon content variant, is also available for use at high temperatures.


Stainless steel 304 has good resistance to oxidation in intermittent service up to 870°C and in continuous service to 925°C. However, continuous use at 425-860°C is not recommended if corrosion resistance in water is required. In this instance 304L is recommended due to its resistance to carbide precipitation.


Where high strength is required at temperatures above 500°C and up to 800°C, grade 304H is recommended. This material will retain aqueous corrosion resistance.
