Magnetic test
Magnetic test is the simplest method to distinguish annealed austenitic stainless steel from ferritic stainless steel. Austenitic stainless steels are non-magnetic steels, but will be mildly magnetic after cold working at atmospheric pressure: pure chromium steels and low-alloy steels are both ferromagnetic steels.

Stainless steel has many excellent properties, beautiful appearance, long service life, and can be 100% recycled, so it is widely used.
The advancement of stainless steel smelting process technology, especially since the 1960s, the use of off-furnace refining and continuous ingot technology has further promoted the rapid development of stainless steel, improved the quality of stainless steel, increased the yield rate, and reduced production costs.
