Stainless Steel 904L Plates & Sheets

High-Performance Stainless Steel 904L Plates & Sheets

Inconel 625 Seamless Pipes
Our 904L plates and sheets step up when regular stainless steel simply cannot handle the really tough operations, particularly in hostile industrial environments with unpleasant acids or salty conditions. They are especially made to withstand corrosion far better than the standard materials. Smart combinations of high alloys such as nickel, chromium, molybdenum, and copper (while maintaining carbon low) fend against pitting, crevice corrosion, and stress cracking rather powerfully.
You'll find them robust in chemical processes, out at sea, or in delicate medicinal tools. Basically, Solitaire Overseas's 904L is a great alternative for your challenging projects if you require something extremely strong, dependable, quick to weld, and that satisfies difficult standards like ASTM A240 and EN 1.4539.

What is Stainless Steel 904L Plates & Sheets?

Thus, technically referred to as UNS N08904 but known as 904L, this steel is a specific kind of low-carbon stainless steel—austenitic, if you're inquisitive. The fact that we have included particular quantities of copper and molybdenum into the mixture truly distinguishes it. Why? Those additives give it real strength to fight powerful, corrosive acids, particularly challenging ones like sulfuric acid. It is also heavy in nickel and chromium, which are excellent in preventing a particular kind of failure known as chloride stress corrosion cracking. All taken together, you get a steel that people truly trust for applications where you absolutely require great solid strength and corrosion resistance.

Chemical Composition of Stainless Steel 904L plates & sheets

The outstanding properties of Stainless Steel 904L stem directly from its precise chemical makeup. This balanced composition is the key to its superior performance in diverse corrosive media:
Element Percentage (%) Key Benefit Contribution
Nickel (Ni) 23.0 – 28.0 Stress Corrosion Cracking Resistance
Chromium (Cr) 19.0 – 23.0 General Corrosion & Oxidation Resistance
Molybdenum (Mo) 4.0 – 5.0 Pitting & Crevice Corrosion Resistance
Copper (Cu) 1.0 – 2.0 Resistance to Sulfuric Acid
Carbon (C) ≤ 0.02 Reduces Carbide Precipitation, Improves Weldability
Manganese (Mn) ≤ 2.0 Strength & Hot Workability
Silicon (Si) ≤ 1.0 Oxidation Resistance
Phosphorus (P) ≤ 0.045 (Controlled Impurity)
Sulfur (S) ≤ 0.035 (Controlled Impurity)
Iron (Fe) Balance Base Metal
This carefully controlled composition ensures consistent and reliable resistance across various challenging environments.

Applications of SS 904L Plates and Sheets

Curious as to where this super-resistant 904L steel finds actual application. Well, it appears everywhere things become particularly demanding or corrosive:
  • Chemical Plants: For heat exchangers, reaction vessels, pipework, and condensers—basically, everywhere they handle unpleasant acids—they depend on it.
  • Marine Environments: You will find it in difficult boat fittings, propeller shafts, seawater cooling systems, and essential desalination plant components needing resistance against saltwater.
  • Pharmaceutical Industry: Here, keeping things pure is crucial, hence 904L is a perfect choice for processing gear, tanks, and pipes since it does not readily rust.
  • Oil and Gas: Particularly in cases of corrosive hydrogen sulfide (H₂S), it is employed in demanding locations such as offshore platforms, pipelines, heat exchangers, and pressure vessels.
  • Pulp and Paper Production: Like digesters and processing systems, bleaching equipment must handle strong chemicals, hence 904L is a good choice.

Advantages of Choosing Stainless Steel 904L Plates

So, what are the perks of choosing Stainless Steel 904L, especially from Solitaire Overseas?
Here’s the rundown:
  • Incredible Corrosion Resistance: It laughs off hostile surroundings where other stainless steels could have difficulty. Where it counts most, you get dependability.
  • Toughness You Can Rely On: Whether structural or under pressure, it's robust and long enough for those heavy-duty uses.
  • Sticks Around for the Long Haul: Because this steel doesn't break down readily, it lasts longer. Think less repairs and replacements to save money and hassle.
  • Works for Many Jobs: It is adaptable and fit for a great range of industrial applications; it is also easy to manufacture.
  • Meets the Standards: Knowing that our steel is produced to satisfy strict international quality and safety criteria helps you to relax.

How to Choose the Right Stainless Steel 904L Product?

Choosing the correct path guarantees the steel's best performance and longest lifetime. Here is something to consider:
  • What's the Job? Actually give the particular conditions some thought. Which compounds are involved? Using what concentration and temperature? The steel will be under what physical stress level?
  • Plate or Sheet? Usually utilized for erecting buildings or pressure tanks, bigger plates are preferred; thinner sheets are ideal for covering surfaces or less heavy fabrication work.
  • Size Matters: Specify precisely the width, length, and thickness you need. Verify whether the measurements and their tolerances fit your project exactly.
  • Check the Paperwork: Ask always for the Mill Test Certificates (MTCs). These records show that the content satisfies the particular criteria you require—such as ASTM A240 or EN 10204 3.1.
  • Your Supplier Counts: Working with someone dependable and informed changes things. At Solitaire Overseas, we offer quality you can rely on, technical support when needed, and consistent service right from start. We do not only sell steel.
