What is 316L stainless steel jewelry?
Among the wide variety of jewelry materials, there is a special material that is 316L stainless steel, which has a bright surface and can be processed into jewelry instead of gold and silver, The price is much cheaper than gold and silver, and it has strong corrosion resistance, It is very suitable for making jewelry that is in contact with the skin for a long time. At the same time, it is precisely because it can not be deformed or discolored for a long time, so 316L steel is the most common stainless steel material, Best for jewelry.
316L is an austenitic stainless steel with improved machinability, 316l steel jewelry is produced by different processes and equipment, usually including CNC cutting, sandblasting, laser engraving, etching, oil painting, gem setting, casting, polishing, PVD plating and other processes.
The addition of Mo to 316L stainless steel greatly improves the corrosion resistance of the product, especially in terms of pitting and crevicecorrosion in chloride environments, 316L can resist atmospheric corrosion and moderate oxidizing and reducing environments. It also resists corrosion in polluted marine atmospheres. The alloy has excellent resistance to intergranular corrosion in the as-welded state.
316L stainless steel also provides higher fracture stress, creep and tensile strength at elevated temperatures. As a fully austenitic steel, it has excellent toughness, even at low temperatures. This low carbon version of 316l steel is not affected by sensitization caused by grain boundary carbide precipitation when heated, so it is widely used in biomedical implants, marine applications, food processing equipment, body jewelry, it is easy to shape and process , although its relative toughness means better machining is usually achieved at lower speeds and heavier feeds.

Heat capacity ratio
- 316L has a Pitting Resistance Equivalent Number (PREN) of 25 compared to 19 for Alloy 304.
- Higher resistance to pitting and crevice corrosion in seawater than 304 stainless steel.
- The low carbon version of Alloy 316 is thus unaffected by grain boundary sensitization Excellent forming and welding properties.
- Excellent ductility and impact strength at high ambient and sub-zero temperatures.
- Non-magnetic unless heavily welded or cold worked.
The advantages of 316L stainless steel jewelry
1. High strength, not easy to deform
The tensile strength of 316L stainless steel jewelry is 686-1176mpa, and the density is only 60% of that of steel, which determines the high strength of 316L stainless steel jewelry.
2. Strong corrosion resistance
The super corrosion resistance of 316L stainless steel jewelry comes from the addition of Mo to its elements, which makes it suitable for use in harsh conditions. In the air below 550 °C, a thin and fine oxide film will be formed on the surface of 316L stainless steel. Therefore, its corrosion resistance is better than that of most stainless steels in oxidizing media and strong alkalis such as atmosphere, seawater, nitric acid and sulfuric acid.
3. Low price
Stainless steel jewelry is not a precious metal like gold or silver, it is less expensive, but its workmanship is just as good.
Jewelry has a long history, but stainless steel jewelry is only more than 60 years old, because of its strong corrosion resistance, hypoallergenicity, excellent toughness, excellent forming and welding properties, it can make a rich variety of jewelry, and because it is cheap , has gradually enhanced the reputation of stainless steel in modern materials and accessories, and is deeply loved by fashionistas all over the world.
