How to distinguish between spring steel and stainless steel
Mainly depends on the performance of spring steel, good elasticity, stainless steel toughness. The color should be slightly white stainless steel. Spring steel is easy to rust, with a little salt a day you can see the stainless steel does not rust.
With saline in two days to put a steel can see rust is a way (can, for 304 stainless steel 201 stainless steel will rust, only less); another way is to put the two kinds of steel can see the reaction is on spring steel in dilute sulfuric acid, oxalic acid, not the reaction or reaction of small stainless steel.
Stainless acid resistant steel, or stainless steel, is made up of two parts: stainless steel and acid resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel resistant to chemical corrosion is called acid resistant steel. Spring steel is a quality carbon steel, but it can rust.
