The most common questions about 904l watch
What watch uses 904L steel?The new Ball Roadmaster Icebreaker uses the 904L steel made famous by Rolex and offers strong features at a competitive preorder price. Stainless steel is not all created equal.Aug 21, 2019
Which is better 904L or 316L?It has incredibly high corrosion resistance. This is critical for some applications, but 316L is more than enough for most luxury watchmaking. Type 904L contains more chromium, molybdenum, and nickel than 316L. However, it also contains some copper, manganese, and silicon, which enhances corrosion resistance.Oct 25, 2021
Is 904L softer 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.Nov 6, 2020
Does Rolex use 904L steel?That is why Rolex uses Oystersteel, a steel alloy specific to the brand. 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.
Is 904L super duplex?The corrosion resistance of 904L is equivalent to most super duplex stainless steels (SDSS) across a wide range of applications. However, Ferralium 255 provides superior performance in sulphuric acid due to its increased copper content of 2%, unique amongst super duplex stainless steels.
Is 904L harder than 316L?According to this site (which proclaims to be the leading online publication for the Materials Science community), 904L is no more difficult to work with than 316L: “Grade 904L stainless steels are high purity steels with low sulfur content. They can be machined using any standard methods.”
Is 904L heavier than 316L?The 904 has a lower carbon content (C), so the polished 904L steel pipe or sheet steel has a better surface, and the same volume of 904L stainless steel is much heavier than the 316L stainless steel. Their Rockwell strength (HRB) is less than 95, and the strength is almost 490MPa.Jan 14, 2021
Is 904L steel more scratch resistant?The real deal here is that 904L steel offers a different shine - more interesting and brilliant - than 316L steel, which tends to look a little more dull. And yes - what Francis Jacquerye has said in his answer is true: 904L scratches more easily than 316L.
Is 904L stainless 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.
When did Rolex use 904L?904L STEEL In 1985, Rolex became the first watchmaking brand to use this steel from the 904L family for its cases.
What 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.
What is the best stainless steel grade?304 stainless steel is the most common form of stainless steel used around the world due to excellent corrosion resistance and value. 304 can withstand corrosion from most oxidizing acids. That durability makes 304 easy to sanitize, and therefore ideal for kitchen and food applications.
What is Oystersteel made of?Oystersteel is a steel superalloy specific to Rolex, which belongs to the 904L steel family. So what exactly makes 904L different from traditional steel? 904L is a low-carbon, high alloy stainless steel, with additives of copper, chronium, nickel and molybdenum.Nov 9, 2018
Does Tudor use the same steel as Rolex?Tudor uses 316L stainless steel for all its watches and has always done. Tudor's bigger brother Rolex, on the other hand, uses 904L stainless steel, which can explain people's curiosity about whether Tudor follows the same footsteps. ... In 2003 Rolex's entire production line changed to 904L steel.
What does Steelinox mean?In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable", is a steel alloy with a minimum of 10.5% chromium content by mass.
Do Rolex watches have nickel?Rolex and the Reason for 904L Although 904L is more difficult to make and consists of extra materials such as chromium, molybdenum, nickel, and copper, it has numerous benefits. ... Rolex has been using 904L in watch cases since 1985 and from 2006, it began to utilize 904L in the band.Mar 22, 2017
Does Rolex use stainless steel?Stainless steel is not all the same. Steel comes in various types and grades… and most steel watches are made from a type of stainless steel called 316L. Today, all the steel in Rolex watches is made from 904L steel, and as far as we know, pretty much no one else does.
What grade of steel does Rolex use?OYSTERSTEEL. A Rolex watch must work perfectly and maintain its beauty even in the harshest environments.
