904L Stainless Steel Sheet

904L Stainless Steel Sheet is a high-alloy austenitic stainless steel sheet, classified as an ultra-low carbon, high-corrosion-resistance grade material.

Key Features:

High Corrosion Resistance: Contains a high proportion of nickel (Ni), chromium (Cr), and molybdenum (Mo), offering excellent resistance to strong acids (such as sulfuric and phosphoric acids) and marine environments.

Ultra-Low Carbon Design: Minimizes the risk of intergranular corrosion and ensures more stable welding performance.

Good Processability: Can undergo various processing operations—such as cutting, stamping, and welding—though its strength is slightly lower than that of duplex stainless steels.

High-Cost Material: Due to its high alloy content, its price is significantly higher than that of standard 304 or 316 stainless steels.

Typical Application Areas:

Chemical processing equipment (in acidic media environments)

Marine engineering and shipbuilding components

Oil and gas installations

High-purity systems for pharmaceutical and food processing

High-corrosion-resistant storage tanks and heat exchangers
