Nickel 904L is a fully austenitic nickel with additives and a low carbon content. It is one of the strongest metals when it comes to resisting corrosion; it is non-magnetic with excellent formability, toughness, and weldability.
Uses of Nickel 904L – Wiring, Oil Refinery Components, Gas Scrubbers, Seawater Cooling, Paper Processing, Acid processing plants, and more!
Nickel 904L Characteristics
Corrosion Resistance – 904L has a higher Nickel and chromium count making it ideal for corrosion resistance. It still ahs a high amount of Iron which gives it the majority of it’s strength.
Chemical Composition – The primary elements are Nickel and Chromium which at a minimum represent ~23% and ~20% minimum. This means that corrosion resistance is the highest. Than in descending order: MO (4%), Co(2.5%), MN(2%), Si(1%), and Cu(1-2%). Then you are going to balance it with Iron which means it will range between~+47%.
Weldability/Machinability – The metal is highly treatable and easy to meld and machine depending on what you need. The balance is right where you can make fine adjustments with no problem at all.
The Rolex Difference – Rolex which had previously only used 904L nickel for certain parts of their watches, recently transitioned to completely 904L. This was because they needed a metal with a higher resistance to wear and tear and corrosion that they weren’t getting with 316L.
