Corrosion Resistance
304 has excellent corrosion resistance in many  environments and when in contact with different corrosive media. Pitting and crevice corrosion can occur in environments containing chlorides. Stress corrosion cracking can occur above 60°C.

 

Heat Resistance
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 .

 

Applications
304 stainless steel is typically used in:Sinks and splashbacks ,Saucepans ,Cutlery and flatware ,Architectural panelling ,Sanitaryware and troughs ,Tubing ,Brewery, dairy, food and pharmaceutical production equipment, Springs, nuts, bolts and screws stainless steel pipes in bundle for packing.

 

304 seamless stainless steel pipe is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment. 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features. It is also a common coil material for rebuildable vaporizers.And with“the heavy quality, heavy service, good reputation”of the good reputation are sold well all over the country, and exported to America, Europe, Southeast Asia and other retions.
