Why do we choose 316 medical grade stainless steel?
316 stainless steel is a kind of austenitic stainless steel. Due to the addition of Mo element, its corrosion resistance and high temperature strength are greatly improved, and it can be used under harsh conditions.
1. Insulation effect: because the 316 stainless steel vacuum flask contains nickel, the toughness of stainless steel is better, and the fatigue resistance is much better than that of 304, so that the vacuum time of the vacuum flask is longer, and the thermal insulation effect remains unchanged for several years.
The material of 304 stainless steel is relatively hard, with a little rigidity, and is relatively easy to crack. After a few months of use, the insulation effect of the vacuum flask will be significantly reduced.
2. Heat resistance: The high temperature resistance of 316 stainless steel can reach 1200-1300 degrees, and it can be used under harsh conditions. 304 is only general-purpose stainless steel, and the general high temperature resistance limit is 650℃.
3. Corrosion resistance: Due to the addition of Mo element, 316 stainless steel has suitable corrosion resistance in various organic acids, inorganic acids, alkalis, salts, and seawater, and the corrosion resistance is far better than 304.
