What are watches made of?
- stainless steel
- White gold
This steel is one of the compounds and alloys of iron, carbon, and cream. This alloy and combination are used in watchmaking, which has the advantage of positive points. These stainless steels are very light and can be used in watchmaking. In addition to being very light, steels are also very resistant to corrosion and impact. But there is a point about the fact that watches made of stainless steel can be easily damaged compared to mobile watches of other materials. In the click mode, it can be said that the stainless steel used for watchmaking is very resistant to impact and corrosion, does not scratch easily and is usually the most popular material for watchmaking.
Ceramics are also a combination of zirconium acid. Watches made of ceramic also have some advantages, including the fact that they are very resistant to heat and have a very high durability. It should be noted that astronauts use this combination of ceramics in the space shields of the spacecraft shuttle, the reason for using this combination is that ceramics are very resistant to heat. Watches made from this combination are very elegant and light, many users who have provided this type of watch have expressed satisfaction.
Titanium with other elements can be used in combination and alloy. Watches made of titanium alloys have some strengths and advantages. The use of titanium in watchmaking makes production watches very comfortable and light because titanium itself is also very light. Watches made using titanium are highly durable, while titanium weighs about half as much as stainless steel. But the use of titanium in watchmaking both makes the watch lighter and more durable. Although titanium weighs less than stainless steel, it is twice as strong as stainless steel. However, the price of titanium is very high, and it is almost difficult to work with. All sports watches are made of titanium.
White gold is also a metal that is very expensive. This metal, which is pure and precious, is used in combination with alloys. White gold can be combined and used with some metals such as silver and palladium. It is worth noting that white gold, which is an expensive pure metal, is also very popular and looks and works like stainless steel. To make watches that are supposed to have a high durability and continue from generation to generation, it is better to use white gold to make them.
As we said, stainless steel is a compound in which about 10 or 30% chromium is used. When chromium is combined with carbon, it can be more resistant. This resistance obtained from the combination of carbon and chromium can also be corrosion resistance or heat resistance. To increase the corrosion and impact resistance of stainless steel, it is combined with elements such as nickel, molybdenum, titanium, aluminum, niobium, copper, nitrogen, sulfur, phosphorus, or selenium, which results in an increase in the alloy. Its resistance to corrosion
Stainless steels are first melted in electric furnaces or oxygen furnaces and then refined in another tank to reduce their carbon content so that they can reduce their carbon content.
It is worth noting that there are more than about 100 grades of stainless steel, each of which is formed in combination and alloy with some elements.
- Austenitic stainless steel:
There are different types of stainless steel, one of which is austenitic stainless steel. Austenitic stainless steel contains 16 to 26 percent chromium and 35 percent nickel. Due to this composition, this stainless steel has a higher resistance to corrosion and impact. The amount and percentage of carbon used in austenitic stainless steel is about 0.08%. The amount and percentage of elements used in austenitic stainless steel is 18% chromium and 8% nickel.
- Martensitic stainless steel
This type of stainless steel has a high carbon and low chromium composition and has a magnetic property, which is called magnetic ferritic stainless steels.
- Stainless steel duplex
This type of stainless steel is also a combination of ferritic stainless steel and austenitic stainless steel. The amount of chromium used in this type of compound is higher and the amount and percentage of nickel in these steels is less.
- Stainless steel ferrite
This type of stainless steel also has less chromium in its composition and alloys, so that the chromium balance used in this type of stainless steel is between 10.5 to 18. This type of steel is less resistant to corrosion compared to austenitic stainless steels.
What are the advantages of stainless steel?
Stainless steel, due to its composition, has been used in industry for more than 100 years and has many advantages. This metal has many advantages that the number of applications is increasing every year. The need to produce stainless steel has increased. With the increase in production, the cost of producing it has become somewhat more economical. One of the advantages of stainless steel is that it has a very polished and shiny surface. For this reason, they can be used more in the consumption and production of decorative items and products. That is why they use this metal in the production of beautiful and luxurious watches, which has a more affordable price and a shiny surface. In watchmaking, the use of metal that has good resistance to both corrosion and impact as well as heat and heat, having a good and beautiful surface is important, and that is why stainless steel is a good choice and option that It can be used for watchmaking. In addition, the metal is easily recyclable, so we can say that half of the stainless-steel products are obtained from recycling.
What are the uses of stainless steel?
As we said, stainless steel has a high resistance to corrosion and impact, heat, and heat, and that is why this metal can be used in the manufacture of all kinds of cutlery. In addition to being used in the manufacture of cutlery, the metal later entered the chemical industry and was used there. Small or large parts of watches are made of stainless steel, due to high strength, affordable price, beauty, and shiny surface in the production of various parts, small and large watches can be used. In general, stainless steel can be used in the chemical industry, in the production of decorative items such as watches, in the manufacture of functional devices such as cutlery, restaurants, medical equipment, architecture and construction.
Stainless steel grades
- 200 series: This series of stainless-steel grades for austenitic grades can be used, which this type of stainless-steel grades have manganese. The amount and percentage of nickel used in these stainless-steel grades is about 5% or less. These types of steels can be used in the manufacture of small and large parts of washing machines, cutlery, tableware, and beverages, and in the manufacture of machinery and parts, and even in the manufacture of decorative accessories such as watches.
- 300 series: This series of grades also contains carbon, nickel, and molybdenum. Adding the element nickel to this compound gives better formation. This type of steel can also be used in the automotive parts industry, food containers and watchmaking.
- Series 400: This series of stainless steels are made of alloy and a combination of ferrite and martensite and are suitable for grinding operations. Therefore, this series of stainless-steel grades can be used to make all kinds of heat-resistant watches. The corrosion resistance of this series is less than 300 series, but it has a very high resistance to abrasion and heat. This is how we can say that this series of stainless-steel grades can be used to make all kinds of sports watches.
They use different types of metals to produce watches, but it is better to use stainless steel to produce watches that are resistant to heat, heat, corrosion, and wear. Of course, stainless steel also has some compounds and series that must be Carefully selected the appropriate and desired series and combination.
