Kitchen stainless steel storage jar sets


1. Different chemical composition: Generally, stainless steel is added with metal elements such as nickel, chromium and manganese on the basis of iron and carbon to make it have anti-rust properties. 304 stainless steel contains more nickel and chromium than 201 stainless steel, and manganese ratio 201 stainless steel is less.


2, chemical properties: nickel-chromium metal mainly plays a role in corrosion resistance, 304 stainless steel contains more nickel and chromium, corrosion resistance is stronger than 201 stainless steel.


3, physical properties: 304 stainless steel toughness, 201 stainless steel toughness is insufficient, the stretching process requires a large force, and easy to crack.


4, safety performance: 201 stainless steel with high manganese content, harmful to the human nervous system, 304 stainless steel safety is a food grade material, the current food grade stainless steel is 304 stainless steel and above.


5, the price: 304 stainless steel contains nickel, more chromium, good corrosion resistance, expensive, 201 stainless steel price is low,


6. Scope of application: 304 stainless steel has good corrosion resistance and is used in outdoor buildings. 201 stainless steel has good acid and alkali resistance and is used in interior decoration pipes and industrial pipes.
