Stainless steel pipes and tubes are essential components in several industries for carrying fluids and gases. With countless available options, it can take time to pick the right one for your project. One such popular type of Stainless Steel Pipe and Tube is 904L.
What are Stainless Steel 904L Pipes Features?
Stainless steel 904L pipes are a type of austenitic stainless steel that boasts excellent resistance to corrosion in various acidic environments. They are a low-carbon version of stainless steel that provides superior resistance to crevice corrosion, pitting, and stress-corrosion cracking. Stainless steel 904L pipes have higher resistance to other forms of corrosion, like general corrosion, than conventional austenitic stainless steels. Additionally, 904L pipes are known for their good weldability and formability, making them an ideal choice for several industries like chemical processing, oil and gas, and more.

What are Stainless Steel 904L Tubes' Corrosion Resistance?
Stainless steel 904L tubes are renowned for their fantastic corrosion resistance in harsh environments. Due to its high levels of chromium, nickel, and molybdenum, 904L tubes resist chloride stress corrosion cracking, crevice corrosion, and pitting. 904L tubes can handle high sulfuric, phosphoric, and acetic acid levels, making them ideal for harsh chemical environments. Additionally, the superior corrosion-resistant properties of 904L tubes make it a preferred choice for industries requiring corrosive environment protection.
What is Stainless Steel 904L Pipes' Chemical Composition?
Stainless steel 904L pipes have a unique chemical composition that differentiates them from conventional stainless steel pipes. 904L pipes contain higher percentages of chromium, nickel, and molybdenum than other stainless steel pipes. The chemical composition of stainless steel 904L pipes includes Carbon (max) 0.020, Phosphorus (max) 0.045, Chromium 19 – 23, Nickel 23 – 28, Sulfur (max) 0.035, Manganese (max) 2.00, Silicon (max) 1.00, Molybdenum 4 – 5, and Copper 1 – 2. This unique chemical composition gives 904L pipes better resistance to corrosive environments than traditional stainless steel pipes.
What are Stainless Steel 904L Tubes Heat Treatment?
Stainless steel 904L tubes are non-hardenable austenitic stainless steel that does not require heat treatment. However, 904L tubes can be annealed at temperatures ranging from 1900°F to 2100°F and then quenched in water or air to improve their corrosion resistance. But, when 904L tubes are exposed to temperatures above 1000°F, they may suffer intergranular corrosion that can reduce toughness and corrosion resistance. Therefore, keeping 904L tubes within the recommended temperature range is essential to enjoy their excellent properties.
