Do you understand stainless steel?

Stainless steel refers to a type of steel that has anti-corrosion properties. Commonly referred to as stainless steel is the general name of stainless steel and acid-resistant steel. Stainless steel is not necessarily resistant to acid, but acid-resistant steel is also stainless steel. Stainless steel is a type of steel that resists atmospheric corrosion and weak corrosive media; acid-resistant steel is steel that resists corrosion in various corrosive media. Stainless steel is not non-corrosive, but the corrosion rate is slow, and steel that is absolutely not corroded does not exist. It is worth noting that in the same medium, the corrosion rates of different types of stainless steels are very different, and the corrosion behavior of the same stainless steel in different media is also very different. Because of the characteristics of various types of stainless steel, it is important for the correct selection and use of stainless steel.

The normalized stainless steel is classified into ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, austenitic-ferritic duplex stainless steel, and precipitation hardening stainless steel.

304 austenitic stainless steel itself is not magnetic, after drawing, forging, bending will produce heavy enough working magnet; 201 stainless steel parts in the hydrogen retreat and solid-free recovery after the same as the non-magnetic - magnetic And (material) anti-rust is not any relationship. Pursue stainless steel non-magnetic friend, please confirm before buying, so as to avoid unnecessary misunderstanding.
