The material selection for stainless steel water bottles mainly considers 304 and 316.
304 stainless steel
304 stainless steel is a common food-grade stainless steel with good corrosion resistance and high safety. It is widely used in food and medical equipment, and can resist the acid and alkali substances used in daily life to ensure that the water quality is pure and odorless. The disadvantage of 304 stainless steel is that its corrosion resistance is not as strong as 316 stainless steel, but it performs well in most daily use scenarios.
316 stainless steel
316 stainless steel has better corrosion resistance and higher safety than 304 stainless steel. It contains more molybdenum elements and can be used in more severe environments. It is particularly suitable for coastal areas or places where high hardness water is used. The 316 stainless steel liner can better keep the water pure, is not easy to rust, and has a longer service life.
