There are many stainless steel bowl materials on the market, 316 stainless steel and 304 stainless steel are relatively common, so which is better between 316 stainless steel and 304?
1. First of all, 304 stainless steel 304 is the most common stainless steel. Many kettles and word-of-mouth tea filters are made of this material. The density of 304 stainless steel is 7.93 g/cm3 and the high temperature resistance of 800 °C is widely used in food and medical treatment. In the industry, everyone calls it food-grade stainless steel, so the safety performance of 304 stainless steel is still very good.
In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced according to the American ASTM standard.
2. Besides, 316 stainless steel 316 stainless steel is a kind of stainless steel. Due to the addition of Mo element, its corrosion resistance and high temperature strength are greatly improved. The high temperature resistance can reach 1200-1300 degrees, and it can be used under harsh conditions.
316 stainless steel is also the main user of food industry and surgical equipment. Another feature of 316 stainless steel is that there is basically no phenomenon of thermal expansion and contraction.
Both 304 and 316 stainless steels are food-grade stainless steels, and both have certain safety performance, but 316 stainless steel has better corrosion resistance and high temperature resistance than 304 stainless steel.
