904L Stainless steel strip is a high-performance, super-austenitic alloy designed to deliver exceptional corrosion resistance in aggressive environments. With its elevated nickel, chromium, molybdenum, and copper content, this material excels in applications where standard stainless steels (e.g., 316L) fail. Ideal for aerospace, chemical processing, marine, and pharmaceutical industries, 904L strips combine durability, versatility, and reliability.

Key Features
Superior Corrosion Resistance
Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich settings.
Performs exceptionally in sulfuric, phosphoric, and acetic acid environments.
Excellent Mechanical Properties
High tensile strength and toughness, even at elevated temperatures.
Outstanding fatigue resistance and ductility for forming and welding.
Formability and Weldability
Easily fabricated into complex shapes without compromising corrosion resistance.
Welds seamlessly using standard techniques (TIG, MIG, SAW).
Copper Addition
Enhanced resistance to reducing acids (e.g., sulfuric acid) due to 1.0–2.0% copper content.
