Is stainless steel magnetic?

classification:


Stainless steel, in short: stainless steel is not a steel that does not rust, but a steel that does not rust easily. In 1910, it was discovered that the addition of 12% chromium Cr to plain carbon steel has corrosion resistance and oxidation resistance properties. So in the general definition, containing 12% of chromium Cr to be called stainless steel.
According to the national standard GB20878-2007 stainless steel and heat-resistant steel grades and chemical composition of the clear definition: stainless steel, stainless, corrosion resistance as a characteristic, chromium Cr content of at least 10.5%, and the maximum carbon content shall not exceed 1.2%.
But according to the recent national standard GB20878-2007 stainless steel and heat-resistant steel grades and chemical composition of the clear definition: stainless steel, stainless, corrosion resistance as a characteristic, chromium Cr content of at least 10.5%, and the maximum carbon content shall not exceed 1.2%.
