What is 904L alloy?
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 Alloy 20 used for?
Alloy 20 is used in a variety of industries, including chemical processing, petrochemical and refining, marine, pharmaceutical and food processing. End use applications include storage tanks, mixing tanks, agitators, pump and valve parts, food processing equipment, fasteners and fittings.
What P number is Alloy 20?
The P Number of Alloy 20 is 45 according to ASME BPVC Section IX.
Is alloy 825 stainless steel?
Description of Incoloy 825
It is the high level of nickel in combination with the amount of molybdenum and copper in this nickel alloy produces substantially improved corrosion resistance in a corrosive environment such as reducing environments compared to stainless steel.
What is better 316L or 904L?
In this case, 904L stainless steel is the clear victor over 316L; with an average PREN value of 36.7, it is much stronger than 316L (which only has a PREN of 26.1). Therefore, 904L is more likely to withstand the corrosive power of seawater.
How strong is 904L steel?
Mechanical Properties
| Grade | Tensile Strength (MPa) min | Yield Strength 0.2% Proof (MPa) min |
|---|---|---|
| 904L | 490 | 220 |
What is P no in ASME?
A P-Number is an alphanumeric designation assigned to a group of materials. These materials are grouped based on their similar weldability and mechanical characteristics. P-Numbers are assigned to base metals to reduce the number of welding and brazing procedure qualifications required to perform work.
What P number is 5 chrome?
5B
Base Metals: The P Number
| P Number | Base Metal |
|---|---|
| 5A | 2 1/4 Chromium, 1 Molybdenum |
| 5B | 5 Chromium, 1/2 Molybdenum or 9 Chromium, 1 Molybdenum (two Group Numbers) |
| 5C | Chromium, Molybdenum, Vanadium (five Group Numbers) |
| 6 | Martensitic Stainless Steels (Grade 410, 415, 429) (six Group Numbers) |
Is alloy 825 the same as Inconel 825?
Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum, copper and titanium. It is an alloy that provides high levels of corrosion resistance to both moderately oxidizing and moderately reducing environments. Alloy 825 is similar to alloy 800 but has improved resistance to aqueous corrosion.
What is alloy 400 used for?
Alloy 400 is one of the most widely used materials for marine applications, shipbuilding and seawater desalination plants. The alloy exhibits very low rates of corrosion in flowing sea or brackish water.
Is 904L 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.
What grade of stainless steel does Rolex use?
Most watches today use a stainless steel graded 316L. But, Rolex being Rolex, the company uses a unique blend of high-quality 904L stainless steel made by their in-house foundry. Just recently, it has been baptized as the Oystersteel.
What P number is 5 Chrome?
What is the difference between Inconel and alloy?
Inconel Alloys versus Incoloy Alloys. Composition is the most critical difference between these two superalloys. Inconel is a predominantly nickel-chrome alloy containing 50% of nickel. Incoloy is a nickel-iron-chromium alloy with less than 50% nickel.
Is alloy 400 same as Monel?
MONEL is a trademark of Special Metals Corporation under which a series of nickel-copper alloys are grouped. Commercially there are many types of MONEL available, such as alloy 400, alloy 401, alloy R-405, Alloy K-500 and Monel 404. The Monel 400 alloy is also known as super alloy monel.
Does 904L steel scratch easily?
As you can see the rockwell number of the 904l is even lower so it cannot be more scratch resistant. A. The main advantage of 904L over 316L is its resistance to acids: “The addition of copper to this grade gives it greatly improved resistance to strong reducing acids, particularly sulphuric acid.”
What steel does TAG Heuer use?
stainless steel
We use stainless steel from the 316L family of steels, often used in the high-tech industry. Our alloy has a low carbon content, which makes it particularly resistant to acid-induced corrosion. Whether you are at your sports session or racing on the circuit, your steel timepiece is the ideal companion.
