Frequently Asked Question
The most common questions about 904l vs 316l
Is 904L better 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
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
Does 904L steel scratch easily?I was surprised to learn this from a reliable source but yes, 904L does scratch easier than 316L. It seems that Rolex' motivation for choosing 904L is its higher resistance to acidity.
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.
Should I wear my Rolex everyday?One of the best things about owning a Rolex watch is wearing it and enjoying it every day. This daily, constant wear is one of the best ways you can care for your watch. While Rolex watches are famous for their durability and robustness, your Rolex will inevitably gain scratches and dings while you wear them.Feb 21, 2020
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.
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.
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.
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.Jan 12, 2021
Is 316L stainless steel good for jewelry?316L stainless steel jewelry It's advantageous due to the composition of molybdenum elements that improve its resistance to harsh conditions and high temperatures. People opt for 316L stainless steel jewelry because of its exceptional tensile strength.Feb 28, 2021
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 is 904L material?Alloy 904L (UNS N08904) is a superaustenitic stainless steel that is designed for moderate to high corrosion resistance in a wide range of process environments. The combination of high chromium and nickel content, coupled with additions of molybdenum and copper, assure good to excellent corrosion resistance.
What is 316L 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.
Is 316L stainless steel hypoallergenic?In the fashion industry, the 316L stainless steel is widely known as hypoallergenic stainless steel. The reason behind this is simple – this stainless steel alloy does not contain any metal that widely causes allergic reactions.
What does the L in 316L stainless steel mean?316/316L Stainless Steel: The 'L' Designation The L denotes the low content of carbon in the steel. 316L is best known among fabricators for being resistant to cracks after the weld process is completed. This makes 316L the preferred choice of fabricators who look to build metallic structures for industry 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 type of stainless steel does omega use?OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.
What is the difference between 316 and 904?What's the difference between 316 and 904 flue liner? ... As a result, 904 grade, is more resistant to corrosive chemicals than 316 grade , such as the acidic by-products from burning fuels, that would typically congregate in a chimney flue.
