316l stainless steel strip vs 317l stainless steel strip

What Is The Difference Between 316L and 317L Stainless Steel Strip?

There are numerous types of stainless steel on the market, but what is the difference between 316L and 317L stainless steel strip?

These may sound like two totally unrelated questions, but the answer has a lot to do with what type of application you are using the stainless steel strips for.

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 317L Stainless Steel Strip?

317l stainless steel strip

Compared with conventional chromium-nickel austenitic stainless steel such as 304 stainless steel strip, 317L stainless steel strip has stronger resistance to chemical corrosion.

In addition, compared with conventional stainless steel strip, 317L stainless steel strip has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance.

It is low carbon grade or L grade, this grade has anti-sensitization performance during welding and heat treatment.
