The difference between stainless steel 18/10 and 18/8 mainly involves the content ratio of chromium and nickel.
Explanation of meaning: “18/10” and “18/8” of stainless steel represent the mass percentage of chromium (Cr) and nickel (Ni). “18” represents the chromium content, and “10” and “8” represent the nickel content respectively. 18/8 stainless steel: iron + 18% chromium + 8% nickel; 18/10 stainless steel: iron + 18% chromium + 10% nickel.

Influencing factors: The difference in nickel content directly affects the grade of stainless steel. The higher the nickel content, the better the rust resistance of stainless steel, because nickel can improve the corrosion resistance of stainless steel.

Application fields: There is a common saying in the stainless steel industry that 18/8 stainless steel is usually considered “food grade”, while 18/10 stainless steel is considered “medical grade” because 18/10 stainless steel is more corrosion-resistant and suitable for medical use Equipment and other fields.

Representative materials: The representative of 18/8 stainless steel is 304 stainless steel, while the representatives of 18/10 stainless steel include 304 stainless steel and 316 stainless steel. Both are common types of stainless steel.

General Application: In general, for daily cooking needs, pots and utensils made of 18/8 stainless steel are usually sufficient because they have better rust resistance.
