Use and distinction about 18/8 and 18/0 stainelss steel

ON USE

1). 18/8 stainless steel has 18% Cr and 8% Ni. It is belong 300 series stainless steel grade family, without magnetism. And its typical model is 304 grade stainless steel. 

USE: Kitchenware, Exterior material, Buliding material, Automobile component, Medical appliance, Chemistry, Food technology, Fiber industry, Ship's parts, and so on.

2). 18/0 stainless steel has 18% Cr and 0% Ni. It is belong 400 series stainless steel grade family, with magnetism. And its typical model is 430 grade stainless steel.

USE: Surface of the gas-cooker, Home components, Kitchenware, Use for decorateing inside buliding, Washing bath, Inner tub of washing-machine, and so on.
