Stainless steel is highly resistant to rust and is not susceptible to corrosion from moisture or perspiration. Furthermore, skin irritation caused by wearing stainless steel components is extremely rare. This makes stainless steel the ultimate and most desirable material choice for watches and jewelry.
There are three main types of stainless steel, and their quality can vary depending on the purity grade. These three types are 304, 316L, and 904L. Most fine watches utilize 316L watch case to provide a high quality product at an affordable price.
To understand the different types of stainless steel, you must first understand the components of stainless steel. The basic mixture of metals - carbon, iron, and chromium - will have different mixtures of nickel, manganese, or nitrogen added to it. 304L and 316L are made by adding nickel to the mixture, while 904L is a subgroup of silicomanganese steel.
Containing 18-20% chromium and 8-10.5% nickel, 304L is widely used in the manufacture of common household items, and as a result, most watches made from this stainless steel are usually low-end watches. Due to its ductility, 304L is also more susceptible to corrosion than 316L and 904L stainless steels. This alloy mixture also contains more carbon than 316L, giving it a significantly darker color.
316L stainless steel is more in demand in the watch industry because of its higher chromium and nickel content and also contains some molybdenum for better corrosion resistance.The “L” in 316L stands for the low carbon content. However, it is also widely used in the medical field for surgical instruments. Due to its high resistance to chlorides, stainless steel is also common in the petrochemical, food and pharmaceutical industries, nuclear reprocessing, and marine applications.
316L stainless steel is used in products that require extensive welding due to its stability at high temperatures and under highly corrosive conditions. As a result, 316L stainless steel is widely used in most high-end watches and reliable, durable dive watches due to its qualities such as best price and anti-magnetic properties. More specifically, There are many 316L watch cases in the market.
Highly acid resistant, 904L stainless steel is used in building heating, pollution control and bleaching equipment and is the most expensive metal. However, due to its high production cost and the difficulty of processing the steel, 904L Stainless Steel is primarily used by Swiss luxury watch brands. Since 18 years ago, they have only used this stainless steel in watch production. 904L stainless steel contains more chromium, molybdenum, and nickel than 316L, and even copper, manganese, and silicon - for enhanced corrosion resistance.
The 316L watch case from CARISEN has won wide acclaim in the industry for its excellent quality and unique features. This case is made of high-quality 316L stainless steel with exquisite craftsmanship, and has extremely high corrosion and wear resistance. The appearance is exquisite, with smooth lines and high gloss, showing a noble and elegant temperament. Meanwhile, the case structure is reasonably designed to ensure the accurate operation of the watch and make it more comfortable to wear. In addition, the 316L watch case of CARISEN also has good impact resistance, which can remain stable in all kinds of harsh environments, providing the wearer with long-term reliable companionship.
