Based in Houston, Texas, George Metals is a reputable producer and supplier of high-end stainless steel goods, with a focus on thin 904L stainless steel plates. These plates are widely used in industrial, petrochemical, chemical, and marine settings where strength and durability are crucial due to their exceptional resistance to corrosion. George Metals is dedicated to providing precise, effective solutions for demanding applications. Customers looking for strong, long-lasting materials for extremely corrosive and crucial service conditions choose our 904L thin stainless steel plates because of their outstanding dependability in harsh environments.
In addition to iron and trace elements, stainless steel 904L is an austenitic alloy that contains nickel (25–28%), chromium (19–23%), molybdenum (4–5%), and copper (1–2%). Its resistance to acids, chlorides, and pitting corrosion is improved by this composition. Tensile strength of about 520 MPa, yield strength of about 200 MPa, and elongation of up to 40% are examples of mechanical properties. Additionally, the alloy has outstanding structural durability, weldability, and formability. Because of these features, thin 904L plates are perfect for high-performance uses in the aerospace, marine, and chemical processing industries.

Stainless Steel 904L Flat Bar is widely used in chemical processing, oil and gas, marine, pharmaceutical, and pulp and paper industries due to its exceptional corrosion resistance, particularly in acidic, chloride-rich, and high-stress environments.
Stainless Steel 904L offers superior corrosion resistance compared to standard austenitic stainless steels, excelling in harsh environments with strong acids (sulfuric, phosphoric) and chloride exposure, due to its high nickel, chromium, and molybdenum content, reducing pitting and stress corrosion.
Yes, Stainless Steel 904L Flat Bar is highly suitable for marine environments due to its excellent resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making it ideal for shipbuilding, seawater equipment, and coastal structural applications.
Thin SS 904L Plates are widely used in high-corrosion settings where robust acid and chloride resistance is required. Heat exchangers, reactors, pressure vessels, and piping systems in chemical and petrochemical facilities are important examples of applications. They are perfect for marine applications like offshore platforms and desalination plants because of their exceptional resistance to stress corrosion cracking caused by chloride. Additionally, these plates are utilized in food processing facilities, aerospace systems, and decontamination equipment where robustness, accuracy, and resistance to harsh media are essential. 904L thin plates are a material of choice for important industrial applications due to their durability and adaptability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
