Why are Kitchen Sinks Magnetic?

Most companies use austenitic stainless steel to make sinks. Theoretically, they will not be magnetic. However, in producing processes, push and stamp will make austenitic steel have weak magnetic. But the generated magnetism is very weak and will not affect the use of the water tank.

Stainless Steel Sinks are commonly produced in 201, 202 and 304 stainless steel models. These stainless steels are austenitic stainless steels, which means that they are all non-magnetic. When the steel sheet is press-formed, due to the mechanical deformation, the surface cube is slightly damaged, and weak magnetism will occur. In addition, some water tanks require heat treatment. If heat is uneven during heat treatment, weak magnetism will also be generated.

Austenitic stainless steel has weak magnetic properties due to deformation and heating, and will not affect the use and life of the sink.
