Is the stainless steel that we often say completely rustproof? In fact, it's not. Stainless steel can also rust, but the elements in stainless steel make it less prone to rust. For example, we usually use 304 stainless steel and 316 stainless steel. What's the difference between these two types of stainless steel? Let me tell you about the differences between these two kinds of stainless steel materials.
1. Food level issues.
People often ask if 304 is food grade? In fact, according to the material, the 304 material content has reached the food level. There are two common food level materials in the market: 304 and 316 stainless steel. 304 is commonly used in small household appliances or water cups. Some 316 are used in medical devices. But we also need to clarify a concept here, which does not mean that the material is food grade, it is food grade, but also includes whether the manufacturing and other links meet the food grade standard, just like xiyouwo is used for decorative stainless steel pipes, while other stainless steel pipe factories are specialized in the production of food grade stainless steel pipes, and the required process links are different.
2. Corrosion resistance.
316 stainless steel is 304 stainless steel corrosion resistance on the basis of adding some molybdenum and nickel elements. In distilled water, drinking water, river water, boiler water and other types of water quality, the corrosion resistance of 304 stainless steel and 316 stainless steel is almost the same. However, when the content of chloride ion in the medium is very high, because 316 stainless steel is an alloy containing molybdenum and nickel elements, it has better corrosion resistance to the environment with high chloride ion, so 316 stainless steel is more suitable.
316 stainless steel is more expensive than 304 stainless steel due to the addition of molybdenum and nickel.stainless steel materials have their specific role and scope of use. Please make reasonable use of their advantages and disadvantages to decorate their space.
