Overview of 904L Stainless Steel Pipe
Yasco 904L stainless steel industrial pipes are designed for the most demanding applications, offering exceptional resistance to corrosion in aggressive environments.
Made from a high-performance austenitic alloy containing chromium, nickel, molybdenum, and copper, 904L pipes excel in resisting sulfuric acid, phosphoric acid, and chloride-induced stress corrosion cracking.The main components are: Cr 18.0-20.0%、Ni 23.0-25.0%、Mo 3.0-4.0%、Cu 4.0-5.0%， Carbon content ≤ 0.03%.
Adding copper significantly enhances the corrosion resistance to reducing acids such as sulfuric acid and phosphoric acid.
Physical Performance and Corrosion Resistance
1.Tensile strength ≥ 490MPa, yield strength ≥ 216MPa, elongation ≥ 35%. Maintaining good toughness at low temperatures, suitable for use in environments ranging from -50 ℃ to 300 ℃.
It exhibits excellent corrosion resistance in dilute sulfuric acid (concentration ≤ 98%) and phosphoric acid (concentration ≤ 85%).Has strong resistance to chloride stress corrosion cracking and pitting corrosion.
