Why are some 316 stainless steel vacuum flasks more expensive than 304 stainless steel? What is the difference? -Alice f

When it comes to stainless steel, we must first know what "steel" is. Steel is an alloy material with iron as the main element, carbon content generally below 2%, and other elements. The stainless steel is formed by adding chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), and molybdenum (Mo) in order to achieve steam resistance, acid resistance, and chlorine resistance. A type of steel.

When you buy stainless steel products, you can see the brands imprinted on the stainless steel, such as 201, 301, 304, 316, 440A, 440B, and 440C. They represent different proportions of the alloying elements contained in them. And 316 grades of stainless steel products are the most common.

The specific differences between these two stainless steel products are as follows:

1.304 stainless steel is the most common type of steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, no heat treatment hardening, and no magnetism. , The applicable temperature is -196℃~800℃. Like water tanks in construction projects, pull baskets and slides in home improvement cabinets, towel bars in toilets, and mobile phone shells are mostly made of 304 stainless steel.

2. The biggest difference between 316 stainless steel and 304 stainless steel is the addition of molybdenum, so its corrosion resistance, atmospheric corrosion resistance and high temperature strength are better, and it can be used under harsh conditions; it has excellent work hardening and non-magnetic. Like high-end sanitary ware faucets, sinks, tableware, and medical equipment, 316 stainless steel is often used.
