Definition And Material Properties Of Stainless Steel

Definition: stainless steel usually refers to the steel that has the ability to resist the corrosion of air, water, acid, alkali salt or other medium. 

Although some steels are rust-resistant, they are not necessarily acid-resistant, and acid-resistant steels are usually rust-resistant. Not all stainless steels can handle all corrosive environments without rusting. In life, people often refer to austenitic stainless steel. 

Characteristics of austenitic stainless steel: non-magnetic under normal conditions, slightly magnetic after cold working; no phase transformation at various temperatures, so it cannot be hardened by heat treatment; Enhance temperature. 

Stainless steel is completely non-magnetic only in a vacuum state.
