Many appliances in our life are made of stainless steel, and there are many kinds of stainless steel. What is the difference between 304 stainless steel and 316 stainless steel?

 What is the difference between 304 stainless steel and 316 stainless steel??

1. Chemical composition is different: 304 has no molybdenum element, while 316 has molybdenum element.

2. The corrosion resistance is different: 304 contains only 9% nickel, while 316 contains 12% nickel, so the corrosion resistance of 304 is worse.
3. Performance difference: 304 has better corrosion resistance, acid resistance and alkali resistance, while 316 has better chloride corrosion resistance and heat resistance due to the addition of molybdenum.

They are very similar in appearance. SS304% SS316 is austenitic, non-magnetic and non-heat-hardening.

1. Different element composition

SS304 – → Chromium – 18%, Nickel 8%

SS316 – → chromium – 16%, nickel 10% and molybdenum 2%

2. Different performance

Adding molybdenum to SS316 helps to resist chloride such as seawater. It is more suitable for coastal cities.

SS304 is usually cheaper and mainly used for kitchen utensils, pots and tanks.

SS316 has high corrosion resistance and can be used for oil refining equipment, pharmaceutical equipment, fasteners, bolts, etc.

3. Different maintenance methods//304 316 Metal Difference IMTP Ring

304 stainless steel: 18cr-8ni-0.08c has good corrosion resistance, oxidation resistance and processability. It is resistant to strong oxygen acid and can be stamped. It can be used to make containers, tableware, metal furniture, architectural decoration, and medical appliances. 316 stainless steel: 18cr-12ni-2.5Mo is common in coastal buildings, ships, nuclear power chemistry and food equipment. It not only improves the corrosion resistance of chemical hydrochloric acid and ocean, but also improves the corrosion resistance of brine halogen solution.

4. Different brands//304 316 Metal Difference IMTP Ring
