Why Is Stainless Steel Magnetic?
Is it true that Angel Juicers are made of stainless steel?
Some customers have said “I heard that magnets don’t stick to stainless steel,
but these magnets are sticking to part of the Angel Juicer’s gears!”
Let’s answer your questions here.
Why Magnets Stick to Austenitic Stainless Steel
While magnetisism occurs during the process of manufacturing stainless steel of the Austenitic Line (SUS300 series) or during processing, there is no magnetism during the steel making (billet or ingot casting) process during manufacturing.
In other words, stainless steel that has been molten and cast does not have magnetism. However, when rolling, turning, or machining after rolling in the rolling process, it becomes magnetic due to hardening of the work.
the steel structure changes to martensite structure due to the work hardening of the machined surface. This magnetism is much weaker than ordinary steel, but it needs to be removed by a magnetism removing device. Generally, in stainless steel manufacturing, it is general not to remove magnetism after post-processing, that is, after plastic working.
For the general public who lacks specialized knowledge of metals, this may be somewhat incomprehensible.
In other words, instead of using the stainless steel raw material as it is, it changes the position of the molecules through various steps such as processing and polishing to make the product, and the atoms are changed and become magnetized.
Angel Juicers are made of 100% stainless steel, so there is no need to worry.
