the difference between 316l and 904l stainless steel strip

What Is The Difference Between 316L And 904L Stainless Steel Strip?

Stainless steel strips are one of the most popular choices for many industries out there.

The strength, durability, and performance make it a top choice for many people.

But what’s the difference between 316L stainless steel strip and 904L stainless steel strip?

Let’s keep reading.

316l stainless steel strip

316L stainless steel strip is almost identical to 316 grade strip.

316L stainless steel strip has lower carbon content imparts even better corrosion resistance than 316.

In addition to its superior corrosion resistance, 316L stainless steel strip also has excellent mechanical properties, including high strength and good ductility at elevated temperatures. It can be heat treated by conventional methods such as solution tempering, quenching and tempering or full hardening to produce hardened parts with high wear resistance.

316L stainless steel strip is widely used in food processing equipment such as sinks, drain boards and tables where it must withstand acidic solutions. In addition, it is often used for equipment exposed to sea water or other chemical environments where it must withstand corrosion from chlorides. HZW offer both polished and bright finish 316L stainless steel strip for your applications.

What is 904L Stainless Steel Strip?

904l stainless steel strip

904L stainless steel strip is a low-carbon, high-nickel, molybdenum super austenitic stainless steel strip.

It has good activation-passivation transformation ability and excellent corrosion resistance.

It has good corrosion resistance in non-oxidizing acids, good pitting corrosion resistance in neutral chloride-containing application.

904L stainless steel strip is suitable for sulfuric acid environment with various concentrations below 70 degree.
