Stainless Steel 304 vs 316 

Stainless corresponds to the English 'Stain-less,' signifying resistance to rust and corrosion, which is less compared to ordinary steel.

Stainless steel is a chromium-infused steel alloy known for its excellent corrosion resistance. The terms 'Corrosion Resistance' and 'Intergranular Corrosion' are concepts related to a metal or alloy's resistance to corrosion. 

This refers to the resistance to chemical reactions that occur when the surface of a metal comes into contact with substances such as oxygen, moisture, chlorine, chemical agents, and more. Intergranular corrosion is the phenomenon of corrosion occurring at the grain boundaries within the metal alloy, primarily resulting from the chemical composition and heat treatment processes of the metal alloy. Prolonged internal corrosion within the metal affects the material's durability and, consequently, the lifespan of the metal material. 

Stainless steel is broadly categorized into several grades, among which Stainless Steel 304 and Stainless Steel 316 are the two most widely used grades.

Therefore, Stainless Steel 316 is primarily used in environments where high corrosion resistance and thermochemical resistance are required, while Stainless Steel 304 is widely used for general purposes. When choosing a product, it's advisable to select the appropriate grade that suits the usage environment and needs.
