What type of steel does Tudor use?

Tudor uses 316L stainless steel for all its watches and has always done.

What steel is used on Tudor Black Bay 58?

Both are made from 316L steel (TUDOR's favoured alloy for its steel watches), however some TUDOR fans are convinced that the black version's material seems darker. Having presented this theory to the horology house, TUDOR reassured me that both models use the same steel material.

Is 904L steel harder than 316L?

Type 904L contains more chromium, molybdenum and nickel then 316L, plus also some copper, manganese and silicon, which makes it more corrosion resistant than 316L. But the main issue with 904L, besides its extremely high price, is that it is still harder to process than 316L.

What is 904L steel used for?

Alloy 904L (UNS N08904) is a superaustenitic stainless steel designed for corrosion and pitting resistance in a wide range of process environments. It is used extensively in the chemical process industry including the production of phosphate-based fertilizers.

Is 904L steel more scratch resistant?

The 904L is often used for body jewelry or piercings and it is not particularly expensive. As you can see the rockwell number of the 904l is even lower so it cannot be more scratch resistant.

Tudor Black Bay Steel Review | Best Tudor Diver?

What is better 316L or 904L?

If we were to look at specifications alone, it's easy to say that, actually, 904L is indeed the superior alloy. It has incredibly high corrosion resistance. This is critical for some applications, but 316L is more than enough for most luxury watchmaking.

What kind of steel does Patek Philippe use?

Watch Applications

The majority of bracelets and cases use 316L surgical steel for its an-allergic properties. Patek Philippe Nautilus. Image source: Patek Philippe Archive.

What steel does Seiko use?

The vast majority of Grand Seiko watches are made of 316L stainless steel, which is generally regarded as the industry standard. 316L is known for its low carbon content (in fact, that's what the “L” denotes), anti-magnetic properties, and its excellent resistance against corrosion.

What did Rolex use before 904L?

It wasn't that long ago that Rolex ditched 316L to 904L. For years, 316L was hailed for its ability to ward off salt water and acidic liquids due to its low carbon content. But around 2000, Rolex noticed that salt water was actually worming its way into the caseback threads and watchband.

What kind of steel does Breitling use?

Breitling uses only top-class metals such as the 316L antimagnetic stainless steel alloy, or grade 2 titanium. Particular care is devoted to the parts most exposed to external influences, such as the crowns and pushpieces. Water resistance is guaranteed by highly sophisticated systems.

When did Rolex switch to 904L steel?

904L STEEL

In 1985, Rolex became the first watchmaking brand to use this steel from the 904L family for its cases.

Does Omega use 904L steel?

Omega utilize 316L stainless steel, which is the industry standard, yet Rolex utilize 904L stainless steel, which offers greater resistance to corrosion and can resist polishing extremely well, making it easier to maintain in the long term.

Does ball use 904L steel?

Select BALL timepieces are now built using 904L steel. Though every timepiece is made to handle harsh conditions, the implementation of 904L stainless steel only fortifies our strength and reliability.

Is Tudor as good as Rolex?

Bottom line: Rolex and Tudor are two of the best watch brands on the market. Whether you're looking for a modest price point, a more avant-garde design, an iconic logo, or a certain timeless elegance, you can find a Tudor or Rolex that will serve as the perfect watch for you.

How tough is the Tudor Black Bay?

It looks and feels like a proper dive watch. However, its water resistance rating of just 200m/660ft only makes it suitable for some light snorkeling, swimming, or showering (in cold water only).

Is 904L steel magnetic?

Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures.

What kind of steel is Oystersteel?

Oystersteel belongs to the 904L steel family, which is particularly resistant to corrosion and acquires an exceptional sheen when polished. 904L steels are commonly used in high-technology and in the aerospace and chemical industries. Their excellent anti-corrosion properties are comparable to those of precious metals.

Is 904L super duplex?

The corrosion resistance of 904L is equivalent to most super duplex stainless steels (SDSS) across a wide range of applications.

Does Rolex use 316L stainless steel?

Rolex Oystersteel

Most timepiece manufacturers use 316L stainless steel, which is more than adequate for the vast majority of applications and environments you are likely to encounter in everyday life.

What Stainless does Rolex use?

For many years Rolex used the popular stainless steel grade 316L, which is the standard for round 95% of the watch industry. In 2001 however, they changed from using 316L to 904L and are currently the only watchmaker in the world to use this grade for their watchcases.

Is 316L stainless steel good quality?

316L is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won't decay, unlike with 316 stainless steel.

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

Chemical differences between 304L and 316L stainless steel:

From a chemical point of view, 304 stainless steel contains 18% chromium and 8% nickel while 316 stainless steel contains 16% chromium, 10% nickel and 2% molybdenum. The molybdenum is added to help resist corrosion.

What is 316L stainless steel used for?

It is commonly used in chemical and petrochemical industry, in food processing, pharmaceutical equipment, medical devices, in potable water, wastewater treatment, in marine applications and architectural applications near the seashore or in urban areas.

What's the difference between 316 and 316L?

316L stainless steel is almost identical to 316. The only difference is the carbon content. 316L's lower carbon content imparts even better corrosion resistance than 316. 316L does not require post-weld annealing.
