304 stainless steel

304 stainless steel

Katalor  professionally is the 304 stainless steel supplier. There are many steel type stock in our Shanghai warehouse, such as SS304 plate, SS304 pipe, SS304 profile steel, SS304 square/rectangle hollow section and so on.  If you need 304 stainless steel specification,contact us!

304 stainless steel / SS304 material austenitic, which has a minimum of 18% chromium and 8% nickel. Type 304 has a maximum carbon of 0.07% . It is the standard “18/8 stainless” that is commonly found in pans and cooking tools. Alloy 304 is the most versatile and widely used alloy in the stainless steel family. Ideal for a wide variety of home and commercial applications, Alloy 304 exhibits excellent corrosion resistance and has a high ease of fabrication, outstanding formability. The austenitic stainless steels are also considered to be the most weldable of the high-alloy steels and can be welded by all fusion and resistance welding processes.

304 stainless steel 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°C. Considered resistant to potable water with up to about 200mg/L chlorides at ambient temperatures, reducing to about 150mg/L at 60°C.
